Campagnolo calliper mounting bolts. BB info.

[bikenut2010]

Hi, does anyone know if mounting bolts for record and monoplaner are compatible?

I have a pair of record callipers with 'incorrect' frame mounting bolts ( just a threaded bar ) and am looking for spares to convert to allen recessed frame fitting.

Also am I correct in assuming that BB spindle 113 mm with world logo takes 1/4" bearings if steel and 3/16" if Ti ?

Thanks for your help in advance!

Re:

I don't think the monoplanar bolt is compatible.

If you have a pair of these:

And you want to convert them from bolt on to recessed, then that's quite easy.

You use the back bolt-on brake on the front - the bolt is about the same length as the recessed front one.

Then you need to find a short bolt for the other brake to use on the rear. Mercian Cycles have some here:

Make sure you swap the brake blocks to the other side so they don't slide out.

Pretty sure your BB assumption is correct, but I don't have a ti one to check.

Brilliant thanks, I have a back nos to swap, so I’ll get the other Mercian... some proper dome nuts would be nice!
