    Avid BB5 to Avid BB7

    I recently purchased a new bike (08 Specialized Rockhopper) that came with Avid BB5 brakes. I would like to move to BB7's. Do I need new cables and levers or can I just swap out the calipers?

    Your old cables and levers will work fine.

    If you do get the BB7 make sure you get the 2008 brakes
    as they have both an inboard and outboard adjustment knob.
    Fantastic brakes!

    I think they changed the shape of the knobs for 2008, but BB7s have always had inboard and outboard adjustment knobs.

    Indeed, the main visible difference between BB5 and BB7 has always been that the BB7 has two adjustment rings.

    True. The knobs are reshaped, plus the inboard knob now has a torx screw, allowing you to tighten/loosen it with a wrench. Much nicer than previous models where you had to jam your fingers in between the caliper and the spokes.

    The 08' BB7's are nice because of the "window" area on the rear caliper that makes the pad adjustment much easier.

    You may want to throw on an SRAM flak jacket for the cable housing for the back brake. It gets rid of that squishy feel.
    Lead by my Lefty............... right down the trail, no brakes.

    Bulk housing works fine. Just make sure the ends are cut nice and straight, open up the lining with an awl, and use some sort of lube (Boeshield, TriFlow, Rock N Roll Cable Magic) on the cable. It helps cut down on friction. Check the cable routing for any unnecessary bends or long loops or tight bends.
