I need some advise on compatibility between the components my bicycle already has and the ones I want to upgrade to.
My current cassette and chain are worn out so I will have to replace them. I need a new shifter anyway since my current is broken. Upgrading could be fun!
Current setup - Scott Sportster 50
- Cassette: Shimano CS-HG31-8 11-32T
- Rear Derailleur: Shimano Altus RD-M370 24 Speed
- Crankset: Shimano FC-M171 48x38x28
- Rear hub: Formula DC-25 RQR disc
Upgrade option 1 - upgrade to 9sp Cassette: Shimano CS-HG400/CS-HG201/CS-HG50 9 speed 11-32T
Upgrade option 2-upgrade to 10sp Cassette: Shimano CS-HG500/CS-HG50/CS-HG51 10 speed 11-32T
It is assumed I will be getting a compatible 9sp/10sp chain and shifter. I want to continue with the 11-32T. The price is irrelevant.
Q1: Which above upgrade options will my derailleur work with?
Q1a: Will I need to adjust the L/H screws and B screw on the derailleur for any of the upgrade options?
Q2: Will the existing backwheel/hub take the 9sp and 10sp cassettes?
Q2b: Will I need a cassette spacer for either of them? Size?
Q3: Will the existing crankset take to the 9sp and 10sp cassette change?
Q4: If I were to go for a 11-34T cassette, would the L/H and B screws on the derailleur need to be adjusted?
Thank you! :)
