Hi, Not sure if that is the correct way to title the request for ideas/expert advice on how to improve on a 10 speed DA7900 GS or specifically drive train (52/39 crank) and I am not sure if this topic was previously addressed?
I am thinking of changing my current 10 speed cog from 11/28 to a 11/32 or if a 10 speed 11/30 exists then that would be a preference. Would that mean a compact crank and smaller chain rings are required? Does a road10 speed 11/32 cog exist?
Is there a 11 speed conversion at all possible without changing anything else besides the drive train?
Criteria for either setup is that it should be light and durable. Don't mind a mix brand of components but it must be compatible and speak to a lesser weight than my current setup.
Are these at all possible and feasible? Any part make recommendations based on this criteria for each option? Don't mind after market parts such a ZTTO 11-32 at 216g as an example. For interest sake, the OMNI Racer 11-28 Titanium Cassette weighs in at 118g but price....?
I don't have any issues with current setup...just wanting to try something new versus upgrading the entire GS or buy a complete new bike. Please share your thoughts.
