Review on 🖤 Black/Silver Origin8 Alloy Ramped Chainrings by Joseph Lang

94mm/32t/8-10sp/5b Much better than I expected. This machine model is the only replacement for my old code set from the 90's. This model uses rivets instead of a stepped ramp. I have a feeling it actually works better than the OEM stamping. Unfortunately, one of the rivets falls too close to 1/5 of the bolts, resulting in a slight flex when the adjacent bolt is tightened. -- this may not be a problem for all sets. But I haven't noticed any issues for over 500 miles with lots of hills.
