Christopher ★★★★★

The 30mm spindle really does make a difference in ankle clearance, and the bearing itself feels much smoother than the stock one I took off. Took maybe 20 minutes to swap out and the creaking I had is completely gone.

Sofia D. ★★★★★

Installed this to replace the old creaking unit on my road bike, and the 30 mm spindle fit perfectly with zero play. The narrower Q-factor is definitely noticeable in the pedal stroke, and after 300 miles it's still smooth and silent.
