Today I showed up at the shop and sure enough the Sram rep was there and he was changing out brakes. I spoke with him for a while and to my surprise my bike ended up on the stand getting Avid's brand new XO Trail brakes installed. I had to leave before he was finished, so I thanked him and headed home.
The XO Trail is Avid's brake that follows close behind the XX model. It is a four piston dual diameter caliper with their innovative lever pivot bearing. Weighing in at just 340 grams they are a 50 gram improvement per brake over my Avid Elixir 3's. As Avid says, "the new XO Trail was born to climb and engineered to descend." Here are the spec's:
I can't wait to get these out on the trail and give them a good test!
