Difference between BB7 disc kit - Front or Rear ??

Postby MichaelB » Fri Oct 15, 2010 2:50 pm

Based on my road conversion :mrgreen: a work mate is considering doing the same to his MTB.

He will need a fork (no dramas), hub & spokes (again, no dramas), but a quick scan on fleabay shows that you can either get a Fr & rear kit (no use for the rear) or a Rear BB7 specific

What stops this being mounted on the front - the mount only ?

I believe you just need a different adaptor mount for the front.

It seems strange that any should be advertised as front or rear as the 185 I bought from CRC came in a box marked "front/rear". It came with a front 185 post mount, a front 185 IS mount and a 185 IS rear mount. Maybe it is some kind of ex-OEM.

Cheers.

The Wiggle version is marked "Front/Rear" but some are marked Rear only.

Thanks for the feedback, it's what I thought the difference was.

The difference is the adapter. IIRC the adapter that comes with it will fit a 160mm front, 140mm rear or something similar. If you have any adapters, grab whatever kit is cheapest. If not, ebay an appropriate adapter too.

As of 2009 Avid made all BB7 brake kits universal fitting as they all contain 2 adaptors one for the front and one for the rear in a box kit for a given rotor diameter but make sure when making a purchase that it is a 2009 version to gain this extra mount other wise read the details to ensure you get the correct kit or buy a rear kit and buy a front mount separately.
