Love this

This is brilliant, love the fact that you can buy separate crank arms. This is a game changer, not having to buy a full crankset when it is just one side broken. Thank you Decathlon

Buy in certain circumstances

DO NOT BUY if you want to attach it to a btwin triban 300 as it needs a square taper crank arm where as this crank arm has a diamond taper. On the website it says for all types of recreational bikes and it says for square taper cranksets but it's completely wrong

Dear Sir,our 
Great Feedback, thank you very much.  I have updated our website and the information will change in a few days to give extra clarification (mind you, going by other retailers websites, very few do!). Your comments are greatly appreciated as I'm sure it will help many other customers.

Tretkurbel in Ordung, nur Preis war höher am Kasse

Warum das Preis am Regal und Internet ist 9,99 euro und am Kasse ich musste 10,99 euro bezahlen??? Tretkurbel ist in Ordnung.
