If you havenât yet caught wind of âplusâ-sized mountain bikes with their semi-fat 2.5 to 3in tyres, youâre going to soon â and in a big way.
Both 29+ and 27.5+ mountain bikes are receiving huge mainstream industry support for 2016, and SRAM and RockShox are on board with new wheels, forks, and hubs all built around the new Boost 148 and Boost 110 hub spacing.
What is Boost, anyway?
