Great for flipping bikes.
If you’re into purchasing old bikes with 3x drive trains and turning them into a 1x for newbie trail riders to start out with, this’ll do just fine and dandy. Not flipping but, you know, flipping.

Looks good but didn’t last
I was really happy when I received it. It seemed very nice. Unfortunately, after a couple hundred miles there was already a lot of wear. My drivetrain was super noisy because of the excess wear on this ring. I have had Race Face rings in the past that have been in use to multi thousands of miles. I’ve never had a chainring wear out before the chain.

Worked for me, no issues.
My old cainring has threads on the chainring, that was my only issue… I couldn’t install them on my ebike… so to make it easier I epoxyed the thread to the chainring and boom all is good. I have not had any issues with it, holder up well even after a few 100 miles… city riding.

Nice CNC quality piece, not the right bolt spacing size though.
Will need to return due to my crank being a 94mm BCD spacing and this one’s 104mm. Wish it worked cause it looks great!

Works as expected
At present I have 20+miles on it and no complaints, It arrives I put it on with ease I didn’t need to excessively tighten the skews and their just as secure as when put on

Pas pour E-Bike !!
Pas pour E-Bike. Attention ça se monte, je l’ai installé sur un EP8, ça fonctionne mais les lumières on pris du jeux et ont cisaillés 3 vis sur 4., plus de vis, plateau tordu , carter moteur rayer….A peine 2 mois d’utilisation en ayant que quelques sorties
