    Rear Brake - 2009 Felt B12 (Tri Bike)

    Just picked up this frame and does anyone know if it needs a specially configured rear brake caliper since it sits behind the crank at end of chain stay? Looks like pulling arm may be restricted by seat tube

    Thanks!

    Just in case you weren't aware, Felt does have a forum down in the Manufacturers section, and the Felt Road Brand Manager, Superdave, regularly participates.

    The best one I've found to date is the TRP T-925-1B U-brake with the rear dual pivot mounting plate. It gives you plenty of crank arm clearnace and Tektro even offers a flexible noodle with a barrel adjuster so you can easily make adjustments between training and race wheel widths.

    The other excellent choice is the Dura-Ace BR7800 caliper (not 7900, not 9000, not 9010). This rear tucks neatly into the space above the BB and is narrow enough not to interfere with the crankset.

    You'll find others with this patented brake location to use the Dura-Ace caliper on their bikes like Scott, Lapierre, Koga, etc....even when the rest of the components are SRAM or 7900 because of the clearance + performance it offers.

    Yeah, but since this question was posted nearly a year and a half ago, I'm guess the OP has already purchased the brakes.

    I'm guessing that he may not be the only one looking. My hope was to provide some help for him or anyone that found the thread in a search. That is why I replied despite the lapse in time.

    Why did you reply?

    Actually this is quite helpful for my B2 Pro. Unfortunately I sold off a set of 7800 brakes before I got the tri bike.
