I recently received a press release from SRAM and it just so happens to cover my favorite topic: MTB brakes! SRAM announced the release of the GUIDE line of brakes. Now, you’re probably thinking (as I did), “Oh great, a new name change for X-9” or something like that. Well, it turns out that is not the case.
SRAM basically went into their bag of goodies and pulled out all their best tech and even added some new tech to produce the GUIDE line. SRAM is looking at going fast as a speed management issue and with GUIDE they’re rethinking what riders want. This new technology in lever design utilizes three new technologies that push the boundaries of ergonomics, power, and modulation.
The new GUIDE brake comes in three flavors: the RSC, RS, and R (Reach Adjust, Swing link, Contact point adjust). And all three flavors share new technologies: Swinglink, TPC Plus, and Pure Bladder tech. The new Swinglink system reduces the amount of dead space in lever movement. Basically SRAM went and added a neat cam system that amplifies the lever movement and at the same time the special cam shape also improves modulation (reducing that on / off feel).
TPC Plus is essentially a change in the internal port compensation timing area. Newer seals and improved surface treatments all add up to a more consistent feel with greater power.
If you own older X-0 or X-9 brakes you will be pleased to hear about the new PURE bladder system. The new bladder shape seeks to create a bubble-free system. Older bladder designs tended to be a pain at times when bleeding was involved. The new Pure system is shaped to evacuate the bubbles from the system.
The buck doesn’t stop at the lever. The new Centerline rotor makes its introduction. Designed to be stiffer, quieter and more consistent with twice as many spokes, this design keeps the rotor running true. Along with that, a longer running center gap in the braking surface reduces the amount of vibration seen in other designs.
This jewel-like beauty is the new guide caliper. You would think a 4 piston caliper would come in at a hefty weight. Not here. There is only a 4 gram difference from this caliper and SRAM’s XC, two piston calipers. The Guide caliper runs two 14mm and two 16mm pistons which pack a decent amount of force.
Look for GUIDE brakes to drop around June 2014. The RSC will retail for $199 MSRP, the RS at $149 MSRP, and it’ll be $129 for the R. Check out SRAM’s website for more details.

I'll let others be the guinea pigs for Sram.
