Hi all
Just a note of caution ...
You need to be careful about using the Campagnolo road BBs with the Pista cranks ... although even we have struggled to get absolutely definitive advice from the factory, we do know that some Campagnolo Pista chainsets do not mate well with the road BBs as there is a difference in the crank tapers relative to the BB axles. They will always mate correctly, however, with the Pista tapers.
The issue is that some cranks "bottom out" on the road BB axle tapers and this can lead to cracking of (normally) the LH crank.
If these cranks and BB have been used together a lot, it's not likely to be a problem in this particular case but knowing a lot of fixie riders frequent these pages (of course ...!) and seeing that these parts might end up split, I thought I'd mention it for posterity!
