The wider rear hub offers you a bigger choice when it comes to chainrings. And finally, Boost improves clearance on the forks and the rear. The compatibility of the Boost 148 rear wheels and crankset. As we’ve already mentioned, the Boost system alters the position of the cassette, which results in a change in the chainline.
Accordingly, Boost 148….it is simply a new hub standard. A standard MTB rear hub comes with a 135mm wide axle. Just a few years ago, it gets wider to 142mm. Now, it goes even further for another 6mm extra wider.
Thereof,
The bike had 12x148mm rear spacing, a development that came about through a collaboration with SRAM and given the name Boost 148. But despite the fact that Trek was the first company to roll out bikes with Boost 148, this isn't a proprietary design.
Also,
To go along with the Boost 148 rear, SRAM has now officially announced Boost 110, which uses a 15x110mm thru axle (as opposed to the current 15x100mm spacing).
