Dura Ace R9150 Di2 rear mech 11 speed Ceramic Jockey wheels in sliver spin really good and saves watts Item stopped working and I have not investigated it but I’m told it should be a simple fix. Maybe a software update. Sold as seen check the pictures It is a used item so some wear and tear scratches are visible but did not affect its working function when it was. Grab a bargain offers set at a very good level P&P as cost with recorded Royal Mail £10.00. Thanks for looking please check out my other items as I’m having a clear out of all my cycling gear that I don’t use anymore and would be useful for someone else. Many thanks.
