My bike is a Scott AFD and is fitted with a triple chain ring, and 7 gears. My local bike shop has advised me that the gear selectors which are ST5510 are badly worn and the indexing is not possible to set up correctly, so need changing. I would really like to keep the 21 gears as I am not very good on the hills and would like to keep the option of a climbing gear. I think the Shimano 105 triple gear set is now obsolete, so what would I change/upgrade them with?
Thanks
Gary
