Great work !!
Used for 2 to 8 weeks
Hi all just to thank Bernardo for helping me with my bike. His great advise and patience to explain everything related with the parts that needed to be changed from my bike and how this should improve the performance of the bike for the next few months was fantastic. The results were great, I’m very happy with the changes done.
I will recommend all my friends to bring their bikes to be sorted with Bernardo. His honesty and knowledge are very much appreciate.
Good triple chainring.
Used for 3 to 6 months
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.
Used for 3 to 6 months
… 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!
Response of the brand
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.
