Formula only recently rolled out the RX, a more-affordable version of its lightweight R1. Weight, however, is still a respectable 351 grams (compared with the 272 grams of the R1). Even more impressive is the power at hand. Whether the trail dips gradually or loses elevation in short, steep bursts, these stoppers deliver smooth, consistent control that is above average for trail brakes with 160mm rotors. The lever is comfortable with very little slop, and provides a good feel for the brake's excellent modulation. Setup was a snap, aided by a two-bolt handlebar clamp. The RX comes with organic pads that give reliable performance on dry trails but suffer in the rain or on steeper descents. Anyone living in wet areas or places with bundles of vertical terrain should opt for the sintered/metallic pads. Also, the RX has few additional features--there's no contact-point adjustment, for example. But then again, this is a simple, effective, relatively lightweight brake at a good price.--Lou Mazzante (www.bicycling.com)
