So, according to the poster beside the fork, they're offering a 15/20mm thru axle with RC2, or the FIT4 with 15mm thru options in all three wheel sizes? What's the point of the 34 then? 36 all the way!
If Fox Say that the axle can accept 15 and 20mm, If I have 20mm Hub axle does it fit, yes but my question is 5mm gap inside my hub and there's no strenght on it. just saying.
