What are you replacing, and can I have them? (I really should fit a road brake rather than the BB7 MTB brake I have... aiming for a Spyre given that a HyRd probably won't meet the budget...)rheicel wrote:Pulled the trigger on TRP hy/rd from Merlin..... My wife will not talk to me for a while now.

I am replacing my Lyras. They are only about 500 km old. I have both black (unused) and silver (500 km used) sets.MattyK wrote:What are you replacing, and can I have them?

For races under AVCC rules it pretty much only has to look like a normal bike and (back towards topic) disc brakes are also allowed (although they are unlikely to be found on a 5.5kg bike).
BTW the I have heard of one instance of a cable operated TRP Spyre SLC where the carbon actuator arm cracked, leading to brake failure. Probably best not to go too weight weenie on brakes. (Except for carbon disc rotors perhaps )
Cheers,
Cameron

That said, aiming for a 6.5kg bike seems fairly reasonable. A bidon and computer/ cadence sensor/ power meter gets it near or near enough. At non-pro level, no one is going to argue about 100g difference. But 8-900g difference on a big climb will make a big difference.
Yeah, I wouldn't go carbon callipers. That seems too scary. But just about any light weight calliper could fail, really.
As for discs, I can't wait to see the tech bring the weight down over the next few years. I have cable discs on an alu cx bike. Once I no longer tow trailers, a carbon framed hydro disc bike is just what the doc ordered for commuting. The new Shimano stuff looks sharp, but the weight penalty will be reduced significantly in a short amount of time. Especially with CX legally using it.

Set up at the rear is straight forward. The tabs on the frame is aligned perfectly and no need to do any sort of minor mod to prevent the pad rubbing.
It took me longer to fit the front due to pad rubbing. Brakes did not come with mountings that allows you to slightly change the caliper angles. I compensate the angle alignment by grinding the caliper mounts where the bolts are seated.
Brakes do have more power than what you will need in a road bike. I weigh 65 kg most of the time and my bike with fully loaded pannier bags probably can weigh as much as 30-35kg.
Riding in the rain doesn't seem to affect the brake performace.
Lever feel is very good. It is paired with Cane Creek CR5. I am not using compressionless cable, and therefore, the rear seems to have more modulation but longer lever throw.
Here are some of the photos...

When Nys goes to Trek in Jan will be interesting to see what he rides.

I am now considering to change the outer cable to compressionless.
Will report again soon....

To save me browsing back, how are they? Overall, are they worth the premium over cable and can they hold a candle to proper hydro (if you have experienced both)? I am seriously looking at these for my roadie disc CX replacement.rheicel wrote:4,200+ km now. TRP HY/RD still works like new. Rear pads are now 80-90% consumed while front are about 60-70%.

Mechanical Tektro Lyra are good enough for Road Bike use. I used these Lyras as temporary brakes and can stop me well both on dry and wet condition.
Now, for the TRP HY/RD, the brakes are overkill for road use which is good. I ended up just using my Disc Road Bike as Road bike as supposed to planned CX bike, so I cannot comment on the CX use of HY/RD's. HY/Rd have less power compared to any of the MTB Hydraulic Brakes I have used before (Hayes, Avid and Shimano), though this can only be attributed to type of rotor or pads.
Downside of HY/RD = long lever throw. Hope it helps.
