It's pretty hard to ignore the increasing number of disc brake equipped road bikes hitting the market recently and by now, we've seen high-profile professional racers nab some serious victories aboard disc equipped machines. Cross, endurance, and gravel bikes were all early adopters of discs where weight and aerodynamics weren't as critical as on full-tilt road racing rigs, and the improved power and modulation, in all kinds of weather, was very welcome. Those advancements in braking didn't go without notice and many professional road racers wanted the disc treatment, despite the slight weight penalty, on their race bikes. Please keep in mind that for professionals with a paycheck on the line and single digit body fat percentages, slight bike weight gains never come easy, but for the rest of us, the performance of discs, despite the half-pound on average weight gain, simply makes sense. Slow adoption among pros is also in part due to the UCI, the governing body for international bike racing, just recently giving disc brakes its full blessings for use in racing. It also has an archaic 6. 8 kilos minimum weight limit which isn't too hard to hit with a lightweight frame, some top shelf-components, and the de rigueur carbon tubular wheelset. For 15 or so odd years, mechanics have added static weight to lightweight climbing bikes just to get them into compliance. Frame designers then realized they could build in aerodynamic features as a way to add some functional weight back into the framesets with tangible benefits. However, with improved materials and technology, those bikes once again tickled the weight limit, and as a way to once again add weight, in the name of functionality, back into the bikes, disc brakes emerged in the pro peloton offering racers superior braking performance. What's perhaps most impressive about these newer batches of aero framesets coming out specifically for discs is there isn't an aero penalty whatsoever over the rim brake versions, and ...

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
