gorfgorf23

Hey
I want to know if there would be serious comprmise by "upgrading" my 3x9 system (11-32 at the back 22-32-44 at the front) :https://www.woollyhatshop.com/shimano-deore-fcm590-3x9-crank-bundle-175mm-44t-silver-chain-11-32-cassette

to a 1x11 system with sram or shimano to a 30 tooth at the front and an 11-42 at the back
I was thinking of getting a sram gx 1x10 with and extra cog or a shimano xt 1x11.

I just want to know weither I would be pushing harder with the new system since i am not a good climber.
thx

Your lowest gear will be about the same.

Both about .7. (.69 and .71)

Divide the front by the back. Gives a ratio.
