Where to Buy

The wheels have changed from WTB LaserDisc Trail 650B with Formula front thru-axle to American Classic 650B XC disc wheels with AC front thru-axle, while both have Maxle Lite rear axles. Other components such as derailleurs, shifters, cassette, crankset and bottom bracket set have also been updated from Shimano to SRAM in the B2. Another improvement is seen in the switch from a Rock Shox Monarch R rear suspension to a Monarch RT which adds a floodgate dial to control pedaling efficiency. Avid Elixir 3 hydraulic disc brakes have been replaced by Avid XO hydraulic brakes with Matchmaker Clamp system that lets you connect the brake clamp and shifters on one piece of hardware thereby reducing clutter on the handlebar. Of course the color is different as well between the B1 and B2, as is the price tag.
