However, the only problem we’ve found with this latest raft of TT/Tri superbikes like Cervelo’s P5X, DiamondBack’s Andean and Parlee’s TTiR disc is that none of the big group manufacturers — SRAM, Shimano, and Campagnolo — offer their hydraulic disc set ups in a TT/Tri compatible form.
So TRP has stepped in with a very neat solution, the TT Hydro, which is designed to work with either 160mm or 140mm rotors. The TT brake weighs in at 352g per wheel and the brake caliper itself is based on the existing Hylex RS, but uses a heat-reducing hydrid piston.

The brake lever houses the master cylinder underneath its outer grip and the lever has been designed to ergonomically suit a low-pro braking position.
Its one hell of a niche product, but still meets a need and you could always use TRP’s TT hydro set up for a singlespeed, disc equipped, low-pro custom build.
