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. Not only does the rear hub get wider, the front hub gets extra 10mm wider. Why?
One thing for sure…the wider hub flange the stronger spoke-bracing angle. This leads to improved stiffness and stability of the wheel as a whole. This increased stiffness leads to more precise and mode effective bike maneuver. Yet, Here are some more advantages from Boost 148.
– A wider rear wheel means a shorter chain stay can be used
– A wider rear hub offers rider more choices when it comes to Chainrings.
– Suspension pivot can be wider, then stiffer.
– Last but not least, it improves the clearance on the forks and the rear.
However, there is a catch if you need to get Boost 148. Its much wider axles on both front and rear hubs affect the position of your disc and cassette. It means you will need to use a specific forks and cranks to be able to use it.
