Schoolboy Error

Just finished building a new set of wheels for my CAADX 105.

As I used Shimano hubs with a centrelock rotor attachment, I fitted a new pair of Shimano XT RT81 rotors, as my existing rotors where bolt-fit and I didn't want to dick about with adapters.

After fitting the wheels to the bike I noticed that the wheels wouldn't rotate due to the spokes on the rotors interfering with the calipers.

I had been aware beforehand that this could be a problem, but after careful scrutiny of a picture of the RT81s decided that they should have enough clearance. As it happens, there is probably only about 1.5 mm of interference, but any is too much.

:cry:

I've now ordered adapters and will use the rotors off the old wheels for the time being.

When I was looking into this before building the wheels, there wasn't really any info on compatibility available, so the reason for this post is to highlight the problem that:

CAADX Promax Render R calipers are not compatible with Shimano XT RT81 disc rotors.

Might come up in a Google search now.

We live and learn!
