Review: Great to replace the 44T that came in my ebike - Good product. I didn't have any problem installing it on my ebike. This size 52T fits perfectly and helps to reduce the ghost pedaling issue that is very common in ebikes
Review: Excellent replacement - Solved a chain jumping issue. Had over 20,000 miles on the old chainring. Installed a new chain, and the chain would slip off the chainring because the pitch was so different. This chainring solved the problem at a much lower price than a Shimano chainring. Look-wish it was silver instead of black. Was easy to install. Fit perfectly. Weight about the same as Shimano.
