Boo Bicycles has been getting a lot of love lately in the cyclocross world, in part due to U23 racer Skyler Trujillo racing the bamboo/carbon Boo RS-X cyclocross bike at Nationals and the World Championships in Louisville, Kentucky. Founded in 2009 by Nick Frey and James Wolf, the Fort Collins-based Boo Bicycles, in their words, “produces custom bikes that can be raced successfully at the highest levels but are designed to provide a lively, forgiving ride which increases stability and traction on descents and reduces fatigue on centuries and grand fondos.”
Boo Bicycles won an award in the alternative material category for its Boo Glissando townie concept bike, but we of course were more interested in the RS-X.
The RS-X has bamboo top and down tubes, as well as rear stays, reinforced and linked with hand-wrapped carbon junctions. A full carbon downtube extends into an integrated seat post. Of interest, as well, is the reinforced rear triangle on the non-drive side, to handle the stress of the disc brake.
An ENVE carbon disk fork completes the frame. Small details, such as the sumi-painting inspired fish along the top tube, and the subtle “b” logo on the headtube, give the bike a nice understated tone, allowing the bamboo itself to be the main visual attraction. Two waterbottle mounts make this more than just a race-day steed, suggesting Boo’s intent that this frame is supple enough for long gravel adventures.
Though each frame is made custom to the buyer’s wishes, the model photographed here is equipped with full Shimano Dura-Ace cranks and drivetrain, Shimano mechanical discs, an FSA K-Wing Compact carbon handlebar, and DT Swiss hubs laced to ENVE XC Carbon rims with Challenge Limus tires.
