I bought this for a friend, fitted it as his old set were worn out and the chain was slipping on the chain ring teeth even with a new chain and cassette. Great price for this item.
… initially operated as smooth as butter, after 6 months / 600miles it turns out it is also made of butter. Would love to attach photos, safely say outer & middle set is mere scrap. Pay for what you get!
In normal riding conditions, as long as the chain is new and not worn when replaced, the chain rings should clearly outlast these distances. If possible, could you DM me with a few photos as I wish to forward them on to b'Twin in France.
I look forward to hearing from you.
