Thoughts on lightweight brakes
Moderator: Moderator Team
Hey there, as some of you C'Dale guys know I'm building a custom Scalpel. I only need a few more items to complete the build and one of them is brakes. I'm torn between the trusty XTR and the new Formula R1R.
Please help. Any advice or recommendations would be greatly appreciated.
Thanks,

There's few threads here about R1's and also MT8's. Consensus seems to be that almost everyone wishes they stuck to XTR. M9000 is pretty light nowadays so it isn't such a compromise on weight like it might have been a few years ago. XTR just work
Avid XX is pretty light too and maybe my favourite brake. Using old Formula R1 Racing now with alu hardware and some tuning, works great

The MT does have reach adjust but what size rotors were they using?
How do you get the Avids to shut up? I can't hear myself think on my team bike (has Avids oh and a 180 rotor so it will stop)
Thanks for the feedback

Different rotors maybe? Could try the new centerline ones if you're not already on them (and are tied into sponsor equipment)
Failing that; new brakes!

Noise can be caused by two things:-
A constant pitch and variable volume is caused by resonance, more common an Avid brakes (and I attribute this to the silly CPS washer mounting system as it reduces stiffness a lot), metal pads are worse than organic (no internal damping), lightweight discs make it worse as well (Ashima, Alligator style), I had this really badly on one setup, organic pads and a slightly heavier rear disc fixed it.
A near constant volume and varying pitch is usually caused by a contaminant, by that I mean grit/dust and not fluids (which if oily reduce friction to the point where there can be no noise as the brake does nothing).

Impoverished weight weenie wanna-be!

I just switched from a set of M975 XTR brakes to a set of older Formula R1 brakes, and the R1s seem to have a lot more braking power than the XTRs. I think the XTRs had some bad pads or something. I've never heard of R1s working better than XTRs.
