Rama Booda Bike trekkingowa – napęd pasowy, piasta z przekładnią, sztywna oś - M
The Booda Bike Trekking Frame Set (belt drive, gear hub, thru axle) is a belt-drive-ready, matte black steel frame with a matching carbon fork and thru axles at the front and the rear. It is made for gear hubs and comes with an integrated headset and an eccentric bottom bracket, so you can build your own belt-driven trekking bike.
Why build on this frame set?
Built for belt drive. A split joint in the seat stay lets the frame take a closed belt, and the eccentric bottom bracket adjusts the crank position to set the belt tension.
Thru axles front and rear. The carbon fork and the rear dropouts are thru-axle designs (rear: 142 × 12 mm), and a front and a rear thru axle are in the box.
Strong steel, kept light. The double-butted cro-mo tubes have a thinner wall in the middle and a thicker one at the load points.
Clean, hidden cables. The frame has internal cable routing, and the fork hides the front brake cable.
Modern brakes. Frame and fork both use flatmount disc brakes.
Ready for fenders. The frame set is fender compatible, and the carbon trekking fork has a mid-upper mudguard attachment.
Carbon trekking fork with thru axle
The carbon fork has a matte lacquer finish, hidden routing for the front brake cable and a thru-axle design. The thru axle tightens with a 6 mm Allen key. Frame and fork both use flatmount brake mounts, and the fork has a mid-upper mudguard attachment.
Rear end for a belt and a hub gear
The rear dropouts take a 142 × 12 mm thru axle, and the split joint in the seat stay is what lets you fit a belt. It is a common worry that the split weakens the frame – it is a misconception. The eccentric bottom bracket adjusts −2 mm to +4 mm with internal cable routing, and ±5 mm without it.
Who is it for?
- Builders of a belt-driven trekking bike. The trekking frame geometry, hidden cables and fender mounts suit touring, commuting and everyday riding.
- Riders who want a low-maintenance drivetrain. The split seat stay takes a belt, and the frame is made for gear hubs.
