Moots is now officially offering their YBB titanium mountain bike frame in 27.5/650B. They were offering a 27.5″ version in YBB and hardtail as a full custom option previously. They’ll have 8 stock sizes for the YBB. The YBB will feature a 44mm head tube, English threaded bottom bracket, 27.2 seat post, and be made out of US made seamless 3/2.5 Titanium Tube set. This will allow those that are not really tall enough to fit a 29er well be able to enjoy the benefits of riding with larger wheels.
