Some words about the Hy-road / HY/Rd brakes.
I'm running a 160 rotor at the front, TRP's own centrelock rotor to be precise. The flatmount standard assumes an adaptor between fork and caliper which can be flipped to allow either 160 or 140 rotors. Which is fair enough but it's a kludgy solution and I can see why Campag have chosen to go for a 160 only front caliper with no need for an adapter.
The first time I used the brakes... well not as much happened as I would have liked! These brakes really do need to be run in over a few hours of riding. With that behind me the brakes are beginning to have proper bite. Good braking with full carbon rims, everyone's got to like that.
One thing though, there is poor access to the upper bolt on the fork adapter with the Hy-road caliper. I've modified a hex key by cutting some length off the short end to have a key with a very short end. This allows good access to the fastening bolt.
There's a 140mm rotor at the rear. The rear caliper is bolted in place from underneath the chainstay which is very convenient, maintenance-wise.
These Hy-road calipers have been modified by replacing the stock actuation arm with one from forum member Joejack951. This clamps the cable inside rather than outside the bolt and is intended for brake levers such as those from Campagnolo that pull slightly less cable than current Shimano. The replacement arms are very nicely machined and very reasonably priced.
