And a choice of manual shifts or synchronised shifting assist modes – SEMI-SYNCHRO or FULL-SYNCHRO – which is a bit like having your own personal assistant! In SEMI-SYNCHRO mode, the rear derailleur automatically adjusts to reduce big jumps in gear ratios allowing you to maintain your pace and rhythm. In FULL-SYNCHRO mode, the front and rear derailleurs work in perfect harmony to get you in the right gear at the right time – so you never have to worry about it. Slick communications with the rear derailleur combined with programmed chain guide control minimises chain drop. And top gear teeth capacity is 50-52T.
