Description: (from sram.com/en/avid/) If hydraulic isn’t your bag, then you owe it to your ride to try the new BB7. It’s more powerful and is easier to set up than any mechanical disc ever. Details like easy pad replacement, precision ball bearing actuation and infinitely variable spring tension means control like you’ve never felt before. Plus, you can pair it with one of our Speed Dial® levers for sweet, adjustable modulation. You can’t get that on any hydraulic. Last but not least, this year we gave the BB7 a tasty new finish, new inboard/outboard adjustment knobs and a beefy two-piece, forged body.
