I need to change my crankset and bottom bracket, is is possible to upgrade to 48 tooth from the stock 42? The front derailleur is shimano Alivo and has a clamp. It could be moved up to a higher position to accommodate the bigger crankset. Will the upgrade work? Or will I have to buy a new derailleur?
Thank you for your valuable responses, I will stick to my stock 42 tooth option. The risk of damage/danger is higher that the merits of high gearing at the top. Presently I am able to use the total gear range without any problem. I don't want to mess with the usability of the system.
