Boo RS-X Cyclocross Bike
Boo cyclocross bikes have been racing UCI Professional ‘cross races since the inception of the company in 2009. Since then, the results have been more than impressive:
15th – UCI World Championship 2015 (Men 17-18)
25th – USAC Elite National Championship, 2010
Regional wins and podiums are too numerous to even count. The Boo RS-X has been featured in VeloNews, Bicycling Magazine, Road, Road Bike Action, Cyclocross Magazine, and many others. It has been heralded as unlike anything else that has ever been raced on the UCI circuit–a sublime ride that is both supple and responsive.
Our dendrocalamus strictus bamboo has a progressive Young’s Modulus curve, meaning it yields to trail roughness for improved handling and increased comfort, but transmits 100% of your power when giving it the stick. That means when the going gets rough, the RS-X shines. The bamboo’s rising stiffness rate allows it to dive into the stutter bumps and chewed up corners without losing traction, but maintain all-out power transfer when attacking or bridging up to the next group on the course.
The other remarkable aspect of the bamboo in our RS-X frame: it has soft lignin between the stiff fibers which damp vibrations that are normally transmitted through the frame to the rider, giving a much smoother feel to the roughest of courses. Throughout a 60-minute event, you’ll notice how easy it is to go full-gas from start to finish. The bike needn’t be driven with too much skill–it’s a forgiving ride that lets you concentrate on putting down the watts and not on staying upright.
Throughout the years of racing the UCI calendar, we have put our bikes through the harshest tests possible in the cycling world. We have had six different professional riders on the RS-X in the last three seasons alone, battling for the podium every time they have toed the line. We’ve broken wheels, handlebars, brakes, cranksets, pedals, saddles, seatposts, and even forks. We’ve blown through prototype dropouts, front derailleur mounts, early chainstays, and more. The RS-X has been through the ringer, and today’s Boo RS-X passes with flying colors.
We have engineered the RS-X with an absolute form-follows-function aesthetic. The fully-housed, internally-routed cables prevent *any* breach of the drivetrain and braking systems. The Press Fit 30 BB has the highest quality feel of today’s bottom brackets, and ensures creak-free performance from the stiffest and lightest BB30 cranksets as well as providing the flexible versatility to run a Shimano system.
The massive 49.6mm straight head tube on the Boo RS-X means maximum moment efficiency when interacting with the frame’s top and down tubes. The front-end tracking is astounding, no matter how rough the course. The RS-X can run any tapered steerer fork, although we match our frames with our own full-carbon tapered disc forks for optimal performance.
Speaking of disc, that’s all we make. That’s all we have made, in fact, for over two years…from the very beginning of the UCI rule implementation we have been slowing down faster and more precisely. The disc brake is no longer an option, it is a requirement.
The RS-X makes every other cyclocross bike feel either harsh, slow, unrefined, or some combination thereof. When you have dendrocalamus strictus underneath you, please make sure to wait up for your teammates…or just lap them!
