The lowdown: Low-profile cyclocross cantilever available in carbon or aluminum
Pros: More adjustable than the previous model and with more stopping power; aluminum option makes them available to a wider audience
Cons: Heavier than the magnesium EuroX they look to improve upon
It seems like every third cyclocross bike I’ve seen this year has white and red TRP EuroX cantilevers. At Eurobike 2012 the company released a lower-profile, more-adjustable version that poaches the ultra-lightweight plate construction from the TRP EuroX, but yields a lower stance, closer to the semi-low profile of the TRP CR959 SL.
The brakes address many of the shortcomings in adjustability for which the EuroX brakes were criticized.
If one were to describe the key differences between the EuroX and the RevoX in a word, it would be “adjustability.” While the EuroX provided the foundation for the design, the new model includes a wealth of features that make it more adjustable.
Spring-tension adjusters permit centering of the brakes by tweaking spring tension. They can also be centered the way the EuroX requires, by sliding the straddle cable through the yoke.
Vertical brake pad height can be changed dramatically thanks to the addition of long slots in the arms. The pad holders can be slid vertically to the preferred height and clamped in place.
Cable tension can be addressed on the fly via barrel adjusters on the end of the straddle cable that can be clamped in place, similar to those on the EuroX. The Avid Shorty Ultimate rim brake also has in-line barrel adjustment, a trait TRP claims “some say… will revolutionize the sport.”
All alterations to toe-in and brake pad angle are made from a single access on the back of the pad holder, using TRP’s Inplace Adjust system. The system is more accessible than it had been on the EuroX, since the straddle cables aren’t stretched over the access point on the new brakes.
The use of road-sized cartridge pads also add to the ease of making alterations, as it opens the availability of replacement pads substantially. Avid Shorty Ultimate brakes share this feature.
Made for mud
As with any cantilever, a lower profile improves stopping power. Potential drawbacks to low-profile brakes can include less finesse and a jerkier braking experience, as well as less mud clearance.
The Avid Shorty Ultimate, which can be set to wide or narrow stance, sacrifices mud clearance when in narrow stance. But the RevoX doesn’t appear to have sacrificed clearance compared to the wider-profile EuroX. They certainly have increased mud clearance over the semi-low profile predecessor, the CR959 SL.
TRP left the spring exposed for ease of cleaning and better performance in the mud.
Choose between white with red hardware, neon yellow “neox” with black hardware or UD carbon with red hardware for the carbon version. The aluminum brakes come in silver or black.
At 130g per pair with titanium hardware, the carbon RevoX is heavier than the magnesium EuroX, which weighs a svelte 107g per pair. What you pay for in weight you gain in power from the lower profile, though.
The alloy version comes in at 150g per pair, and has stainless-steel hardware rather than titanium. By adding 20g you save nearly half the price, though, paying $160 per bike rather than $300 for the carbon version.
