Volagi and the TRP Hy RD Disc Brake

TRP Hy RD Disc Brake


 

The TRP HyRd is a cable actuated, hydraulic powered disc brake. The use of cables allows for cross compatibility with any shifter that uses a cable brake, allowing us to keep the price down with little sacrifice in braking power compared to a full hydro set up. TRPs HyRd brake uses a cable pull system to activate a lever on the caliper that in turn pushes a piston into the hydraulic reservoir and activates the brake. Don’t be fooled – this approach has plenty of power despite its diminutive size. That, coupled with compressionless brake housing gives you a rock solid, nearly full hydraulic feel as the pads lock onto the rotor.

You might also notice the unique appearance of the T25 Center-Lock rotor. This steel rotor with aluminum carrier and center lock only option sheds weight and heat over its predecessor. The grooves you see along the rotor help pump in cool air to prevent heat build up, as well as help remove contaminates from the rotor and pad surface. The channels are treated with an ED (Electro-deposition) coating, much like anodizing, which bonds the coating to the surface of the rotor on a molecular level so that the coating will never wear off.

A staff favorite for its predictability, low noise, and larger pad-to-rotor contact area, the HyRd wont leave you wishing for anything more than longer rides and steeper descents.

Excerpt taken from Velo Magazine article, “Braking Point” by Caley Fretz, Volume 43/No. 3

“Disc brakes are better at being brakes. It seems an odd, obtuse statement, but it’s a highly relevant one. Good brakes are fast brakes. Good brakes are safe brakes. The notion that discs don’t belong on the road because they are too good—which some folks believe—flies in the face of both physics and logic.

Discs are more powerful, with better modulation, across more situations. They are so thoroughly predictable that it becomes possible to ride an increasingly fine line between traction and lockup, braking later and harder, cornering faster and with more control. In our testing, it was actually the best bike handlers who got the most out of them, as they could push the tiers to the ragged edge with confidence. They allow faster descents and quicker evasive maneuvers. They’re simply better than any rim brake, ever.”

Volagi Test Lab: Shimano Ultegra Di2 Hydraulic

By: Omar Sison

When they made their debut at Interbike several months ago, the reviews of Shimano’s R785 hydraulic road brakes were OK, not stellar, but not bad.  Most of the shortcomings seemed to be due to set up (bleed and alignment I suppose) as Shimano’s techs had scrambled to set up their lot of fresh brakes in a short period of time leading up to the demo.

We recently got hold of a set of Shimano’s hydraulic disc brakes.  Though they say “prototype”, we’re confident the production version will be no different than the pair we tested.  Several days passed while the brakes sat on my work bench before I had the time to properly test them.  Whenever I get into something new, I prefer to take my time with it.

This approach has some advantages.  I really get to know a product, what it’s like to set it up and properly align, how much it weighs, what it looks like, how many threads are on the bolts, see how springy the pad spring is, and anticipate any problems it may present for our customers. By the time I was done installing, bleeding, and micro adjusting the system I felt certain that we had reached that landmark moment we’d been waiting for—the day when we had a truly refined version of a hydraulic road disc brake.

Set up:

I won’t say much about this other than that anyone who has bled Shimano brakes will be happy they pretty much require the same gravity bleed.  A clear and concise step-by-step instructional video is available online (Currently only viewable to Retail and OEM via password, but your local bike shop will have access to them) and so long as you have the proper equipment, it should be a good time in the shop.

In the stand:

The number one thing I love about these brakes is the solid tactile feedback, point of engagement in the lever where you can feel the pads contact the rotor.  They aren’t spongy. The lever reach is adjustable, as well as the lever throw.  This is great as it accommodates for variance in handlebar drop styles, hood placement, and hand size.  Such a nice feature!

On the road:

They are as powerful as you want them to be.  They are by far the most predictable brake I have used so far.

Despite the heroic efforts made by other companies to bring hydraulics to road, as expected, Shimano’s long silence has proven to be very much worth the wait.  Though it comes at a higher price, and is currently available only in the electronic shifting version, the upgrade is worth it for anyone looking for the best braking system currently available.
