I've emailed OnOne to ask them what the rear dropout width on their Kaffenback frame is.
...and I'm very seriously considering building my own wheels. How hard can it be, right?

Read this - the technique is simple http://www.icelord.net/bike/ArtOfWheelbuilding.pdf
Don't waste money on a stand unless you plan on building a lot of wheels - inverted forks and cable ties are the way to go...

Most disc frames are 135mm to accommodate the rotor mount, there are some 130mm disc frames but they are rare as hens teeth and then wheels to fit them are even rarer. As for the Novatec hub, I believe that you can't get a 135mm disc rear hub with a Campy freehub. Though similar to BHS they may be able to do it on request.JustJames wrote:My increasingly-less-hypothetical research has let me to Novatec hubs, which are available in 130mm (standard road width) for disc brakes, an can take Campagnolo.

As for building your own, I have done one wheelset already and looking forward to the next. I highly recommend it.

If you do want to build a set of wheels and need a 130mm rear hub, let me know.JustJames wrote:My increasingly-less-hypothetical research has let me to Novatec hubs, which are available in 130mm (standard road width) for disc brakes, an can take Campagnolo.

Have a really set of sweet new Circus Monkey disc hubs that are BNIB. My project thoughts have chnaged hence their sale.
Cheers
Michael B
PS I'm 99% sure the Kaffenback thingo will be 135mm rear though

At this stage I've pretty much decided (so long, hypothetical!) to go ahead with the frame, and build up some wheels using Novatec hubs with Campagnolo freehubs. As Novatec can provide suitable hubs for my requirement in 130 and 135mm width, I guess it makes sense to get the frame first, and then progress from there.
(@MichaelB, if your Circus Monkey hubs can deal with discs and Campagnolo, please drop me a PM.)
Why Campag? Because I like Campag, and because my roadie speaks Italian. No religious war, really. I prefer Campag, but road Shimano for many years and have nothing rude to say about it. I haven't tried SRAM, but have heard good things about it. I know I've recommended Campagnolo a few times in threads in the last few days, but that's only because I think that Euro frames require Campagnolo in order to keep the Universe balanced.
At this stage, having followed a suggestion - the Kaffenback frame - in a thread started by somebody else, I prolly qualify from special thread-hijacking prize.

so say you chose the kaffenback frame (or whatever it's called), how would you choose the right bottom bracket/crank?
as an example, it looks like you need a BB30 and associated crank.
with BB30, does that mean you'd have to have a FSA crank rather than a shimano?
And considering you'd be using disc brakes, does that make buying a full groupset not worthwhile?

any english threaded BB - so could a shimano BB be used? or do you require a BB30 style thingamabobbin?JustJames wrote:It's a BSA (English) thread BB. This was one of the questions that I asked them. So any crankset that is available with an English thread BB, or that will work with an English thread BB will work.

the learning curve for me will come AFTER WAF approval.... now that is a BIG curve

I was a bit worried that the frame I was looking at, a 60cm Red Kinesis Crosslight Pro6 frame will become unavailble by the time I could persuade the good minister to release funds. So, I have stumped up for the purchase myself just for the frame and still hope to get funding approved for the balance of works in the new year.
Ordered from shinybikes.com, the price ended up at 386 pounds deliverd which at current exchange rates is about $582. Which I think is a pretty good price.
Now to plan my requisition request for the other $1400 in parts to build the bike up.
Only question is, do I continue in this thread for a parts discussion, or start a new one.......

You can buy off-the-hook CX bikes for less than that. To DIY will cost comparatively more than buying one pre-built, but for every bike you're going to be compromising quality/durability/weight/bling for price. You buy as good as you can afford... whether that's DA, Sora, or no-name.
I reckon I can build my disc-braked road bike for $1k plus a frame. Either I'm planning on using lower-grade bits than Reman, or I'm going to wheel and deal harder. Or I could be kidding myself

That's pretty much what I'm working on, other than ~$1k for a Chinese Ti frame instead of alloy, and building my own wheels.jasonc wrote:well i was thinkingbarefoot wrote:Might I be so obvious as to suggest... with cheaper parts?jasonc wrote:another $1400?

It's going to take some work to get that kind of build kit for $1k, but I reckon it's doable. So you'd have to be looking at a $400-ish frame... which would be very tight...
But hey, that's all part of the fun isn't it?

Well I've priced it out to $1400, but with say 20% off, which I don't think is unrealistic, it would bring it in to $1120. I think that's starting to look reasonable already.jasonc wrote:it was your thread to start with, go nuts.Reman wrote:Only question is, do I continue in this thread for a parts discussion, or start a new one.......

So, the parts, without any discounts.
Kinesis frame/forks/headset/post clamp $581
Stem - 3T ARX Pro $39
Handlebars - FSA Vero Compact $25, though thinking of going to an FSA Wing Compact $60
Seat Post - Tifosi Carbon $33
Total $97
Groupset
Full Campagnolo Athena $426, except following subbed for brifters, brakes and chain
Chorus Brifters $234 - to get ultra shift
Avid BB7 Road brakes $117
KMC 11 speed chain $36
Total $814
Wheels (self built)
DT Swiss 415 rims $133
BikeHubStore hubs 32/32H $148
DT Swiss Competition 2.0/1.8 Spokes $44
Conti GP4000s $81
Tubes and rim tape $13
Total $420
Other stuff
Cinelli bar tape $13
Clark's gear and brake cables $23 - might be worth getting better ones?
Shimano M520 pedals $24
Carbon paste and headset spacers $20
Total $80
Grand total $1990 ($1710 with 20% off and free delivery)
As this will be a commuter I still probably need mudguards and a rear rack. All other bits and bobs will be transferred from current bike eg. Brooks B17, lights, etc.

I sent an email to them asking about swapping the freehub and they said they could swap the Shimano/SRAM freehub on their MTB disc hubs for a spare Campy freehub they had for a reasonable fee.JustJames wrote:I had a look at BikeHubStore, and I don't see how you can use disc-braked Campagnolo using their hubs.Reman wrote: ...

They still look exactly the same as the BB7 I've had on one of my MTBs since about 2003, give or take some cosmetic differences to the pad adjusting knob.Reman wrote:http://www.this link is broken/Mode ... elID=59434 $65.33 each for 2011, $73 for 2013s. Sorry if I got you excited.
Of course, the road version is functionally different to the MTB version due to the shorter/harder cable pull (is it a shorter lever or a different cam?), but they're really not changing much over time. And neither they should... they just bloody work.
The 2011 one claims to be the same weight as the 2013 one, to the gram... just as an indication.
I wouldn't hesitate to grab a pair of the "old stock" cheapies. I'm kind of tempted to do just that.

Correction: the one on my MTB is an Avid "BBDB".barefoot wrote:They still look exactly the same as the BB7 I've had on one of my MTBs since about 2003
That was before they started giving them numbers and released a down-spec version.
Looks just like a current BB7. Which looks like the BB7s I had on another MTB in the mean time.
Right first time.

You have to be careful what disc you get with the caliper, the bb7 has a larger pad that the bb5, so if the braking surface is to narrow you will get a pulsing feedback as the pad rubs on the connecting pieces.JustJames wrote:I've seen the BB7 caliper only sold online for cheap.

i have just been thru this when buying a new set of wheels i ended up getting the cleansweeps because i knew they would work as that is what came with the bike originally
