IBIS has heeded the call for the 650b mountain biking market. Upon doing so, they might have build their best mountain bike to date, the IBIS Mojo HDR 650b 27.5" Mountain Bike. The new HDR 650b is built upon the all new HDR 160 design; however this bike sports larger 27.5" wheels, meaning you have a faster rolling, more efficient, quicker bike that handles advanced terrain better than any 26" bike out on the market. The new HDR 650b rolls over logs, roots, ruts, and anything else better than it's sister bike, the HD 160. Yes, this bike has 30mm less rear wheel suspension than the HD160; however it's larger 27.5" wheels more than make up for the difference. In doing so, you're riding a bike that rolls over objects better; while requiring less suspension, which means less pedal bob, which of course means a lighter bike with a higher level of efficiency! Featuring lighter carbon fiber unidirectional carbon, ISCG 05 compatibility and SRAM XX1 compatibility, the new HDR 650b will blow your mind. This bike still features IBIS's legendary DW-Link rear suspension, and when coupled with the super efficient Fox Float rear shock, you suddenly have one of the most efficient full suspension mountain bikes on the market. On top of being efficient, the HDR 650b's carbon fiber works seamlessly with the frames suspension to soak up vibration better than ever.
