This isn't a massive problem as I'll likely be running 25mm initially but would like to experiment with 27mm to take advantage of the greater clearance on the Quinn frame (I'll post about this below).
Do you think there's enough room for 27mm tyres and proper mudguard?
Lennard Zinn said they works perfectly but the tech show that the Campag and SRAM/Shimano are not 100% exactly the same, so when I put a bike up on the stand, I can hear a slight chain rub on the cassette that's not obvious on the road.
Wheels (again):
If I'm using Athena then I don't think 5800 hubs will suit the build. I know that they are very good hubs for my intended use, but that level of clashing is something I'd rather avoid. Also, I'm not even sure if you can buy 5800 rear hubs with a campagnolo free hub body?
Looking at campag hubs reminded me of a wheelset I have sitting in my cupboard from a 9 speed bike I had a couple of years ago (this is making me sounds pretty old I think, I'm only 21). They are Open Pro rims (plenty of life in the brake surface) laced onto old Campag mirage hubs, 32 spokes each. Perfect. Well, nearly- the front hub needs some attention, but being cup and cone, I should be able to sort it out with some patience. Also, the Open Pro rim is pretty narrow and over on the wheelbuilding thread the consensus seems to be that anything over 25mm will be a bit squirmy.
This isn't a massive problem as I'll likely be running 25mm initially but would like to experiment with 27mm to take advantage of the greater clearance on the Quinn frame (I'll post about this below). In order to save some dollar until I've shifted some bike bits, particularly the Colnago frameset, I will run these wheels to start with but still with a plan to build up my own at some point.
I think an interesting option to consider when selecting the hub for the build is using shimano 11 casettes/chains on campagnolo drivetrain; Lennard Zinn says here that it works perfectly. This might mean that it is still worth building on a shimano 11 free hub, the advantages being:
