Moots Routt YBB Frameset

The YBB system is a soft-tail design that uses a small elastomer spring at the seat stay junction to provide about 20mm of travel. It doesn't feel like a mountain bike suspension; instead, it subtly mutes high-frequency road chatter and improves rear-wheel tracking on washboard surfaces without sacrificing pedaling efficiency.

While the frame is optimized for 700c wheels, you can technically run 650b wheels. However, keep in mind that doing so will lower your bottom bracket height, which increases the risk of pedal strikes on technical terrain.

Not at all. While 27.2mm is a narrower standard than what you find on many modern mountain bikes, there are excellent gravel-specific dropper posts available in this diameter. It also provides a bit more natural flex, which complements the titanium frame's ride quality.

The YBB system is remarkably low-maintenance compared to full-suspension linkages. You will occasionally need to clean and grease the pivot point, but there are no complex bushings or bearings to replace frequently.

The frame is officially rated for tires up to 700x50mm. This provides plenty of room for high-volume gravel rubber, though your actual clearance may vary slightly depending on your rim width and the specific tread pattern of the tire.

Moots prioritizes long-term serviceability and creak-free performance, which is why they stick with the 68mm English threaded standard. It is widely considered the most reliable and easiest bottom bracket to service, whether you are in a home workshop or a remote bike shop.
