Boo SL-G Custom Gravel Bike
The SL-G is our top of the line custom geometry gravel bike. A road-geometry race bike, the SL-G excels in extremely rough terrain–flint, hard rock, and washboard dirt roads.
Our SL Series represents the pinnacle of bamboo and carbon technology, and is focused on delivering the ultimate performance from both materials. This series is fully-custom and offered on a made-to-order-only basis.
$4495 gets you our fastest, most responsive, and comfortable gravel race frame, hand-tailored to your measurements and objectives. It doesn’t get better than this.
Boo SL-G: Built to fit, rip, and last
Built from a custom BikeCAD designed to your exact measurements and specifications, the SL-G fits its rider like their favorite bibs. Those long days in the saddle stay comfortable much longer than on a stock geometry frame.
Bringing this rig to a halt on loose surfaces requires fat gravel meats and stout stoppers—the SL-G has this covered with ample tire clearance (up to 42mm) and a 12x142mm QR thru axle rear end. We hand-wrap the carbon around the bamboo and a custom-machined axle assembly, then remove all metal to create a custom-molded carbon and bamboo thru-axle dropout. Its stiff, stout, and light.
We also give our Tam Vong bamboo tubing a special interior S-2 glass layer for extra reinforcement. This strong and absorptive material distributes impacts over a greater surface area. Think of a massive, sharp chunk of Dirty Kanza flint striking the down tube–the bamboo and S-2 glass absorb and disperse this impact, deflecting damage and maintaining the frame’s structural integrity.
Going for a clean, low-profile look? The SL-G frame is drilled to accommodate internal routing of Di2 wires and hydraulic brake hoses. The SL-G is also our stoutest frame yet, and it’s backed by the Boo Warranty and our satisfaction guarantee.
Which bucket list race will you be tackling first with your SL-G?
