I got a couple real rides in on the XTR Race M985 brakes and wanted to post for anyone researching. Most info I found prior to purchase was based on OEM complete bikes equipped with Trail versions.
I'm 6'1 200# on a 5 Spot and these things have crazy amounts of 1 finger braking power for trail riding. Enough that I'm glad I didn't get the Trails, which are touted as having even more power due to the servo wave levers. The beauty of the XTRs is they also have great modulation. It's easy to feel when you're at the limit of braking traction and they let you know when to back off.
Reach is adjustable with a hex key, and once set, I didn't find the need to fiddle with it. I'm running this set with stock Race pads, and Avid XX rotors and did not experience noise of any kind.
In short, more power than Elixrs, Juicys, Hayes, and K24s I've run. Better modulation than the K24s, equal in modulation to Elixirs. No noise.
If you're on the fence about the Race versions due to "not as much power as the Trails", Don't sweat it. These things work great and are lighter if you feel you don't need the added dials found on the Trails.
