Top of my list for economic parts when repairing friends bikes
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.
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!
I look forward to hearing from you.
Regards,
Peter Lazarus, National Cycling Manager, DECATHLON
This is a high quality crankset at a very reasonable price. The only whinge is that it could do with stoppers/covers over the bolts at either end
It did a great job before my bike got stolen.
Looking to replace the chipset on your mountain bike hack then look no further. I've fitted 2 of these in the last year, one on my commuting steel Rockhopper and one on my father in law's bike, both easy to fit, smooth gear shifting and durable. Mine's done over 2k miles without issue
excellent finish nice light weight .easy fit
Could you tell me the length of the crank arms. Please.
Peter Lazarus UK Cycling Market Manager DECATHLON
Easy to fit, matched in with current bike gear change etc. Good quality and value for money.
This was for a Riverside five bike. The chain was shot and it was felt advisable to fit a new cassette and chainring at the same time, which is recommended. The total cost was less than £50 - very reasonable. The fitted chainrings were basic Shimano non separable. This item is separable, so next time only the affected ring needs replacing. The crankset also comes with bolts (v. easy to fit) and a little plastic spacer in case your front mech needs repositioning.
Got it from decotholon in quick time and the product is of very good standard. Easy to install . Light weight and works well .
