I bought this 50 external chainring to replace my Campagnolo 50 tooth chainring, but it works less well than the original Campagnolo (Translated review)

By replacing a 53 Campagnolo chainring with a TA one, it is noticeable that when the chain is on the small chainring and on the 4 smallest sprockets, it touches the large chainring. Comparing the large Campagnolo and TA chainrings, it is clear that the Campagnolo chainring is thinner over a larger area than the TA, thus preventing the chain from touching it when on the small chainring. Too bad! (Translated review)

Very good product and totally compatible for a much lower price than the original model. I took the 50 to switch from a 52x36 to a 50x34. (Translated review)

No issues with installation. However, I have a slight chain skip on the 11x34 teeth. The notches for mounting the chain are slightly too pronounced and try to shift onto the large chainring. Too bad (Translated review)

It's the cheapest chainring to replace a Shimano. (Translated review)
