I've read conflicting answers online with this question: Can the SRAM Eagle NX or GX 12 speed cassette fit on my bike? I have a 2016 Kona Precept that currently has a 142 x 12mm shimano deore rear hub and the stock Acera 11-34t 9 speed cassette. I've read I can install the NX with the existing hub or the GX with an XD hub, but I've also been told I can only fit up to an 11 speed cassette on my bike. Basically, can I fit 12 gears on a 142x12mm hub or do they only fit on 148x12mm or larger? My rear rim has pringled so I plan on rebuilding the wheel with a new rim and spokes or buying a new wheel. I'd like to use the same hub if possible, but wouldn't mind upgrading if I need to.
