Hi, as title says. I have returned into cycling after 20 years of break. Got myself a Giant ATX which has 3x8 drivetrain. It is inconvenient for my as in mountains i only ever use 22t chain ring, while for cruising along the beach I only use 32 and 42 chain rings. SO my idea is to change it to 2x8 or even 2x10. Please share your knowledge with me on this one, since local bike shops only prefer to sell me whole group set for 500-600 AUD, which is almost matching the price i've paid for the whole bike? In my understanding 2x8 should be done like this: I remove 32 and 42 chain rings and buy myself a new chain ring 36 or 38t with correct BCD(104 in my case). Also remove stock front derailleur(tourney) for lets say 2 speed Deore. Also change shifter for 2sp unit. In the rear I do not need to change anything(I fill fine with 22t front x 36t rear wright now on any steep hill) In my understanding 2x10 should be done like this: I do all of the above, but replace rear cassette for Deore or similar 10 sp(will it wit without any modification? how to get if it will or will not?), replace rear derailleur with matching 10sp unit. Also change shifter for matching 10 sp unit. Please advice me the components if you can and if I am right on this one? Trying to keep this mod on a budget. Thank you for your time.
