I was skeptical about a cheap 12x142mm bike axle, but TrailBoost feels stiffer than the stock part on my Process 134. Lever folds flush—no more snagging on rocks. Five stars.

Quick release axle makes race-day wheel changes stupid fast. Threading is butter-smooth, and the lever gives great leverage even with gloves on.

Best thru axle for mountain bikes I’ve tried. Swapped it onto my Honzo and immediately noticed less rear-end flex. Worth every gram and penny.
