They should have the equipment and expertise to inspect it properly. If it's carbon, a specialist repair shop may be required. Take it to your Local Bike Shop and ask them. We probably can't tell from a picture just what condition your bike is in.
BB5 ROAD BRAKES CRACKED
"Is this cracked / safe to ride?" - If you have to ask, don't ride it. If you just want to post a picture, this isn't the place for it. You can also consult our FAQ or the list of people willing to help locally. It really, really helps if you can provide pictures and/or video. Post your problems, and we will try to get your bike rolling again. However, the HY/RD pads should self-adjust for wear – something no mechanical caliper does currently – the open hydraulic system should also maintain a consistent pad contact point, and the HY/RD should be lighter than current mechanical-to-hydraulic conversion systems such as from Hope, Tr!ckstuff and even TRP.Īs with the Spyre, there’s an integrated barrel adjuster on the HY/RD, but given the hydraulic system’s self-adjusting nature we expect it to be more of a setup aid than anything else.A community of cyclists - some with questions, some answers Post questions to get help.

One might question why TRP would bother with something so complicated given that much of a hydraulic system’s advantage lies in the way it efficiently transfers lever force into clamping power at the caliper. A conventional brake cable is anchored to a short lever arm on the caliper, which then compresses a small plunger on the on-board master cylinder to clamp the two dynamic pistons on the rotor (AMP’s system, on the other hand, directly clamped the cable to the cylinder plunger and relied on a single-piston, floating layout). The new TRP HY/RD (pronounced “high road”) is even more intriguing with a hybrid mechanical/hydraulic setup somewhat reminiscent of the old AMP Research caliper. New HY/RD combines mechanical and hydraulic features We also have no word yet on whether TRP will release multiple options to accommodate various cable throw ratios from Shimano, SRAM and Campagnolo, but again, the company has done so in the past with some of its conventional dual-pivot rim brakes so it’s not an unreasonable expectation – particularly given that accommodating different cable pulls would require little more than a different bolt-on lever arm. TRP’s new spyre mechanical disc brake looks to be a lighter weight cable actuated option that should appeal to both roadies and ‘cross racers: trp’s new spyre mechanical disc brake looks to be a lighter weight cable actuated option that should appeal to both roadies and ‘cross racers Courtesy
