So measurements have been taken, the wish list drawn up, then the bits bought, the wheels built, and now comes the part we have all been waiting for: putting it all together! Yes, my new mostly new (apart from the frame forks and bottom bracket) bike project has reached the build phase. Now if, like me, you have never actually built a bike from scratch before, there are three ways in which to approach this phase:

a) get a bicycle shop to build it for you. What! I have already spent enough on this bike to buy a new one outright (OK, but not one with these components).

b) watch videos on-line and surf a few cycling forums to get advice on how to do it. Yes, this is a steep learning curve but it should be do-able, although it may take a little longer and you may have to sort through contradictory advice on what to do when things go wrong.

c) marry a spouse who has a relative who is an experienced bike builder, then invite him over on holiday to help you with the build, should someone give you a redundant Genesis Croix de Fer 09 frame-set. This solution either requires extreme forethought and devious planning, or a great deal of luck, the latter in my case.

As I say above, building a bike from scratch involves, if you have never done it before, a steep learning curve. First up, how to fit a headset? There are two techniques for doing this, either use a collection of expensive headset fitting tools or, if you don’t have one to hand, gently tap the headset into the frame with a hammer. Well, we didn’t have a headset press or crown race setting tool, etc., to hand, so we started with the second technique and got the crown race onto the forks. However, the cups were a bit tight and we decided that discretion was the better part of valour, and took it to the bicycle repair man down the road and got him do it.

Another of the early lessons for me was that parts which have been discounted heavily might not have sold well for a reason. For instance, the 3T Bio Morphe Handlebars, could it be these were less than popular because it is an absolute sod to fit Shimano STi’s to them? The band on the STi’s doesn’t allow for a lot of adjustment, and so getting it past the Bio Morph bits is rather difficult. I suspect that 3T, being Italian, would respond to this by suggesting that I should have used Campagnolo, but I don’t know because I haven’t actually asked them.

Next step up the learning curve, do your homework carefully before buying the parts on-line. Knowing that Avid BB 7 are available for road bikes is not enough, as when you do a Google search, you might find yourself on a web page from an internet retailer offering “Avid Ball Bearing 7 Mechanical Disc Brakes” at a very good price, but not saying if they are road or mountain bike (Chain Reaction Cycles expect you to know what you are looking for). Knowing that there is a difference will save you from the embarrassing experience of bolting your shiny new disc brake calliper onto the frame, only to spot that it has “MTB” written on it. It also saves you the frustration of waiting several days for the new parts to arrive, but this does give you time to start writing a blog post.

Even if you don’t have the brakes, there are still other things to get on with, such as fitting the cranks and setting up the gears. I hadn’t bothered to replace the bottom bracket, as the one that was there was suitable for the crank-set I had in mind. However, as the pedals were turned over for the first time, the gentle grinding noise reminded me of the last thing Steven had said to me when he gave me the frame, “… the bottom bracket’s a wee bit worn and probably needs replacing.” Doh, why hadn’t I remembered that before now? Next came the dérailleurs. As I had decided to go for a triple chainset rather than the double which came with it, I had given the old dérailleurs to the Bike Station, without first removing the spacer inside the band on the front dérailleur. Cue a trip to the Bike Station to try and recover it, fortunately they hadn’t yet used the bits I had given them, and we were able to get it back. Phew.

Putting the wheels on prompted a discussion on tyres and tubes. My choice of Continental Ultra Gatorskin 700×28 was considered a reasonable one, but Continental GP 4 Season 700×28 would probably be better, as they would save around 70g per tyre. As for the inner tubes, well the cheapo Airwave ones are, by my own admission, a poor choice. They are really heavy and the one place where saving weight on a bike really makes a difference is the wheels, as the lower rotation mass makes it easier to do things like accelerate and steer. So something like Schwalbe SV20 extra light inner tubes would have been a better choice, as this would save another 100g per wheel. OK, they are intended for 18-25mm tyres, but they can be used with 28mm tyres, you just have to top them up a wee bit more often.

Addendum: after a four day wait, a package from Planet X Bikes (not the cheapest but they had the road disc brakes in stock) finally arrived, but my excitement was short lived when I found they had sent me only one. A quick check of the delivery note showed that I had indeed ordered two, and a phone call confirmed there had been a picking error. So at the time of writing I have yet to finish the build and take the bike out for a test ride.

I have now reached the point in my bike build project where I have (almost) bought all the new parts I need. When I was first given the frameset of a 2009 Genesis Croix de Fer, there were a few other bits in the box. However, having been measured up (see Part 1), I found that some of these parts weren’t the right size for me, i.e., the stem and handlebars. So I knew I was going to have to buy a lot of things. I didn’t set myself a budget, as I didn’t have a sum of money set aside, I just bought the parts piecemeal when had some money. This is one of the reasons why this project has taken so long. As the actually build part of the project is due to start sometime in next couple of weeks, I thought it was time to have a quick review of the buying of the bits.

I wanted to get all the parts as cheaply as I could, having also decided that I wanted to use the highest spec components I could afford. My first thought was to try and wangle as many bits as I could at trade rates, using some contacts in the bike biz. This didn’t quite work out, although I was made a very generous offer of 20% off all components bought from a major distributor (Madison), thanks John. However, when I started searching around on-line, I found that I could get everything I wanted at more than 20% off the RRP, so I thought I would add a few tips here for others.

First off, Google is your friend, just ignore the ads and the “shopping results” and be prepared to go through several pages of results. You also learn to avoid the price aggregation sites, which are useless for the most part.

Another thing, Shimano parts (and possibly other parts) are often far cheaper on German web sites such as starbike.com and bike-components.de, even though you have to pay VAT at 19%. However, unless you are putting in a large order, the delivery charges of 10-15 € can be very off putting.

Closer to home, these were the web sites that I used the most:

  • Chain Reaction Cycles: often have some of the best prices, but don’t tell you when their stock levels are low. So if there is a good bargain, don’t wait until after the weekend. Delivery is free. You get your own account and can track orders. However, if you accidentally order an item that is out of stock, they don’t tell you when they will deliver. If you need to return an item, they give a refund straight away.
  • Parker International: do have some good prices, but don’t tell you when their stock levels are low. So if there is a good bargain, don’t wait until after the weekend. Delivery is free. You get your own account and can track orders. If you accidentally order an item that is out of stock, they will contact you to let you know and give you the option of cancelling the order. If you need to return an item, they may need prompting to give a refund, but they do so without quibbling.
  • Planet-X Bikes: their general prices are not the lowest, but some of their clearance bargains are spectacular, I have found parts reduced by over 70%. Delivery is free. You get your own account and can track orders. I have not accidentally ordered an item that is out of stock or returned an item to them, so I can’t say what they are like in these situations.
  • Probikekit: they do have some good general prices and some of their clearance bargains are also spectacular, I have found parts reduced by over 80%. Delivery is free. You don’t get your own account and tracking orders can be more problematic. I have not accidentally ordered an item that is out of stock or returned an item to them, so I can’t say what they are like in these situations.

Then there is fleabay ebay, which can be a good source of parts, but it can be hit and miss. You may need to consider buying from overseas sellers, which can make for slow delivery. I bought a Shimano Ultegra crankset from an ebay seller in Austria in July which has yet to arrive, but then he is not charging for delivery and has offered to fit it ,when he arrives next week. ;-)

I do feel a wee bit guilty about not making more use of local bike shops, so far the things I have bought locally are the rims and spokes of the wheels I had built, but then I have just been around three of my local bike shops looking for tyres. Nothing special, just a pair of 28mm Conti Gatorskins, one of the most popular commuting tyres in the UK, but do any of my local shops stock them? No, so it is little wonder I shop on-line. However, shopping locally has started to become something of a sport, I have tried several times to buy a saddle from my nearest bike shop (the Tri Centre), but Hugh is always trying to convince me that I don’t really want to buy one, although his brother Stuart has lent me a couple of test saddles to try out.

Time for a update on my bike build project (based on the frame of a 2009 Genesis Croix de Fer), in the last part I talked about spec-ing up the wheel set. Well, the wheels are now built and I just thought I would re-visit the subject with a wee bit of hindsight, not that I have any regrets. It’s just that a discussion I had with Steven (who gave me the frame in the first place) has set me thinking about it some more.

When I drew up the specification for the wheels which I have now had built, I considered a range of rim options. Looking back at them now, I am not sure why I came to the conclusion that the Alex TD17 (Disc) is possibly the best rim for my purpose, this would give me a choice of tire widths from 25mm to 37mm, suits my just fine. Looking again the Alex XD-Lite (Disc), which was part of the original specification, thiswould be also have been a good choice, as it has a tire width range of 28mm to 40mm, and is also lighter at 470g. Maybe I was swayed by the TD17 having an “Anti-Snake bite” design, but I think it was more to do with the narrower internal width. Either way, it is academic, as Alex rims are almost impossible to source in the retail market. Also, I think my final choice of Mavic Open Pro rims is also good for my purposes, even if the tire width range of 23mm to 32mm is a little narrow.

Moving on to the hubs, as I am using Avid BB7 disc brakes, I immediately started looking for six bolt hubs, but could I have used centre lock hubs? Well, it was only after I had had the wheels built that I came across the Avid G3 centre lock rotor and started to wonder if using centre lock hubs could have been an option after all, but, is there any advantage to using centre lock over six bolt?

The main advantages of Centre Lock are:

  • Rotors are always centred on the hub
  • The hubs can’t be written off by a stripped bolt
  • Rotors are stiffer and less prone to bending
  • Rotors are easier and quicker to remove
  • Lighter hubs (about 20g)

The main disadvantages Centre Lock are:

  • The rotors tend to be slightly heavier (about 20g)
  • Limited availability of non Shimano rotors
  • Rotors tend to be more expensive
  • The need for a Centre Lock tool
  • Centre Lock hubs tend to be more expensive

So, at the end of the day you pays your money and makes your choice. I made mine and, having had my wheels built, I find that I have a wheel set that weighs in at 2.1Kg (without rotors fitted), which is no bad.

I thought it was time for an up-date on my bike build project, which is slowly making progress. Just to recap, my project bike is based on the frame and carbon fork of a Genesis Croix de Fer (2009), which I have been given for free. Since my last blog post on this subject, I have been gathering advice and making a wish list of parts.

First up there were a few decisions to be made, such as: do I use straight bars or drops, and do I reinstate the disc brakes or do I try change to cantilever brakes? As well as this, I had to think about which chainset I would like, do I go for double or triple chain rings?

The choice of bars was easy, as I had been given a pair of Shimano STI 105 dual-control levers in a box of bits that had come with the frame. I had also been given drop bars and a stem, but these were not the ideal size for me, so I decided to replace them with some that fitted me, and by getting another pair of drops I wouldn’t need to get new levers. This did mean that I was tied in to using Shimano, but I don’t have the budget to stretch to Campagnolo anyway, nice though that would be.

Next up, reinstate the disc brakes or change to cantilever brakes? The frame and fork both have mounting points for disc brakes, but the forks don’t have mounting points for cantilever brakes, and come to think of it nor does the frame. So that is easy then, disc brakes it is! As I am going to be using drop bars and STI levers, this means that I have to use mechanical disc brakes, and I have been advised that Avid BB7 are the best, so that is sorted, too.

That leaves the chainset and the decision on double or triple chain rings. Having read around a wee bit, I found that the left STI shifter fitted to the Croix de Fer is a triple, even though in its original spec it had a double chainset. So I have the option of using a triple chainset should I wish to do so – which I do, as I am planning to be able to use the bike for touring. The next thing to decide is the range of components to buy. For the 2009 model, Genesis had fitted Shimano 105 components (for the 2010 model this was downgraded to Shimano Tiagra). But the question for me was, if I buy carefully, can I upgrade to Shimano Ultegra? Cue a web search for prices. After some hunting around for the lowest prices I discovered that I could get all the Ultegra bits I wanted for just £20 more that the 105 equivalents. Great, Ultegra it is, then.

I have been lucky with finding discontinued lines for things such as the handlebars, seat post and saddle. I had budgeted for a mid range pair of alloy handlebars, but then I came across a pair of 3TTT Carbon bars at 72% off and in the size I wanted. Together with an alloy stem they came in at £5 under budget! Looking for a saddle, I had the Selle Italia SLR on the possible list, just the standard model with titanium rails, but was delighted when a Selle Italia SLR Carbon Time Ulteam Flow version turned up at about the same price. Isn’t the internet wonderful!

One lesson I learned the hard way when bargain hunting, be quick, I saw an Ultegra Chainset Triple FC-6603 at a very good price, but wasn’t sure is it was a better buy than the FC-6604 (I still haven’t quite worked out what the difference is). So I asked advice (by e-mail) and went away for the weekend, thinking I would buy it on Monday. Sunday evening, having got home, I checked to see if it was still there, only to find that it had sold out and was discontinued, no longer available to purchase. Damn.

Looking back over the above, I realise there is something missing, the wheels. Having asked around a bit, it is generally considered the best way to get a pair of wheels is not to buy factory made ones, but to choose the components and have them hand built. Besides, finding ready made 700c disc wheels is not straightforward. I did try asking Hugh at the Tri Centre (he does a wee bit of cyclo-cross riding, so should know), but then I lost the bit of paper with his suggestion on it, when I went back and asked again, he had forgotten what he had suggested. I did consider trying to build the wheels myself, but I am on enough of a learning curve with this project as it is.

To spec up the wheel set, I decided to start with the hubs and work my way out. Probable the best disc hubs in my price range are Shimano XT Disc Hubs (six bolt), yep, back to the Japanese fishing reel maker again. OK, so Hope hubs are better, but the ones the guys in the bike shop recommended (Hope Disc Pro II) wouldn’t have left much in the pot for rims, let alone spokes and labour. Next up, spokes, well a spoke is a spoke, isn’t it? I thought I would just leave that to the wheel builder to decide. Rims, after much searching for information, I came to the conclusion that the Alex TD17 (Disc) is possibly the best rim for my purpose. It is light (for a disc rim) at only 505g, with a 17mm internal width, which allows for 25mm to 37mm tyres. But there is one small problem, I can’t find anywhere that sells just the rims. The next best disc rim option is the Mavic A317, which is heavier at 538g and, according to Mavic, take tyres between 28mm – 47mm (but I don’t think that can be right a 47mm tyre is very wide for a 17mm rim). The other option is to use Mavic Open Pro rims, technically this is wrong as theoretically disc brakes put greater torque on the rims. However, Open Pros has a reputation for being bomb proof and are widely used with disc brakes on the road. They also have the advantage of being lighter at 435g, but they are narrow at 15mm, which only allows for 23mm to 35mm tyres.

While there are still other details to sort out and I have still got a lot of stuff to buy, I feel that I am making progress…

All my adult life (and most of my childhood) I have owned and ridden bicycles, yeah sure I drive, I learned to drive at 17 and was for a time in my twenties a fully qualified driving instructor, but driving these days just ain’t as much fun as riding a bike. I bought my current bike, a Norco Volante, about six years ago and it has served me well. However, as everyone who cycles knows, the ideal number of bikes can be calculated be the simple mathematical equation i=n+1, where i is the ideal number of bikes and n the number of bike currently owned. So when a friend of mine said that he was going to upgrade his bike with a custom made Ti frame, and did I want his old frame, I leapt at the chance. Thanks Steven!

I was told it would just be a bare frame as all the other components were to be moved to the new frame. However, when the box arrived I found there were a number of other bits which hadn’t been used with the new frame for one reason or another. Just to recap, my new “half bike” is the remains of Genesis Croix de Fer (2009 model) which is a steel framed cyclo-cross bike, with a carbon fork and formerly had cable disc brakes (which is unusual for a cyclo-cross bike, apparently, but something I intend to reinstate).

The box of bits having arrived, I thought it best to check that the frame is the right size for me and to find out what size the new components need to be, before going any futher. I decided that the best way of doing this was to nip down the road to The Tri Centre for a
bike fitting, a bargain at £35. Now, I like The Tri Centre the staff are very friendly and knowledgeable, and the places is stuffed full of bike bling. If I were ever to win the Lottery it would be my first stop in the search for the ideal bike. Of course there is no such thing as the ideal do it all bike, so it would have to be i=n+1 and with a lottery jackpot The Tri Centre is a good place to start.

Mean while back to the story, the bike fitting showed that the was about the right size for me (although I could do with a longer top tube) and with the right sized components could be tweaked to be a good fit. So starts the shopping list; first off wider bars drop (440 mm, the original Genesis Croix de Fer bars were 420mm) and a longer stem (125 mm, the original Genesis Croix de Fer stem was 110mm), the ones in the box will no doubt be welcomed at the Bike Station. Also I now know that when I come to buy, the length of cranks I need is 170 mm. The rest of the drive train I have yet to decide on, but given that I have inherited Shimano 105 STI levers and Shimano 105 Derailleurs, so I have options open to me. As I say above, I am going for disc brakes as I like the better modulation and stopping power of discs, and the fact that you can stop in the wet, also that your rims last longer. The choice here is cable (mechanical) or hydraulic disc brakes, my preference is for cable as they are cheaper and easier to maintain. The original specification gives the brakes as “Shimano BR-R505 Disc”, but I might look around and see if there is a better choice. Then there is the wee matter of wheels, a pair of Bontragers has been suggested, but I am not sure, maybe it would be better to get the rims, disc hubs and spokes separately and have Andrew at the Bicycle Works build them up for me. Or should I take a one day wheel building class at the Bike Co-op and then use the jig at the Bike Station?

Other bits, such as the seat post, saddle and pedals are easy, that is the sort of thing I have already done with my Norco, but I have never actually built a bike before, this is a big learning curve for me. So suggestions are welcome, Oh, and Bernhard, if you are reading this, you are welcome to ride my spare bike next time you visit, so long as you help me build it first…

Addendum: Since writing this post, I have found a number of people visiting this series of posts wanting to build their own bicycle using the Genesis Croix de Fer frame set. While I was given my Genesis CdF frame and fork, I have found that you can now buy the frames here and here.
