I have a Planet X London Road which I used for commuting. It has SRAM Rival gears and brakes and I'm not impressed. The gears whilst positive and reliable are clunky compared to my last bike which had Shimano Sora gears and Techno brakes. The hoods are not comfortable and the brakes are not as powerful. The worst thing is that I have to replace the brake pads every 6 months or so as the braking efficiency drop off. With my old bike, pads lasted about 3 years.
