Press / Reviews
The idea behind TRP's Hy/Rd, which we first got our hands on a couple of years back, is simple. Fully hydraulic systems demand new, very expensive hydraulic brake/shift levers but cable driven discs are often spongy in feel and need manual pad wear compensation. This hybrid uses a hydraulic brake controlled with a conventional cable pull so you can still get hydraulic benefits with your existing brake/shift levers.
Despite initial reservations about cable stretch leading to soft braking feel lever feel and modulation are noticeably better than even TRP’s own stirrup operated Spyre brake (see below). While there is some softness with conventional cables on the rear it’s actually pretty close to a full hydraulic system in terms of fine control and feedback when used with compression-less brake outer from Tektro or another brand. Pad wear is compensated for automatically by the hydraulic reservoir and the barrel style cable tension adjuster plus a lockable actuator arm make set up very easy.
Our initial reservations about putting the hydraulic fluid reservoir on top of the potentially scalding hot brake caliper have proved unfounded too. Our colleagues in Colorado have dragged this brake down 20 mile plus descents without boiling it though and it’s even survived deliberately abusive tandem testing in the UK. That leaves relatively high weight as the only potential gripe but pads (it takes Hope style aftermarket pieces) are widely available and price is reasonable too.
Verdict: The ultimate control upgrade for disc-compatible cable brake bikes
One thing is for sure, if I had the choice between other mechanical to hydraulic brake systems out there and the HyRds, the latter would win out for sure.
First impressions are good…it’s nifty that TRP was able to pack all that into such a small form factor.
Like it or not, disc brakes are coming, but up until the recent launch of SRAM’s Hydro Red, true hydraulic disc brakes have been very elusive.
TRP got in early with its Parabox converter, though like all cable-to-hydraulic converters it adds complexity and extra weight. But its all-new HY/RD simplifies the issue of cable to hydraulic actuation.
This contains the hydraulic fluid reservoir master cylinder within the calliper itself (old-school mountain bikers may remember a similar design on the original Pro-Stop discs in the early Nineties),
which means you can run any shifter setup you like – SRAM, Shimano or Campagnolo – and their electronic versions too.
TRP has also worked on countering potential heat build-up issues by using composite pistons that can manage heat better than traditional steel.
At 195g per wheel plus 89g for the rotors the HY/RD is no heavyweight either.
