Hi I have just been given this by my postie. https://www.mbr.co.uk/reviews/hardtail/gt-zaskar-27-5-comp-2016-review
which I want to change from 2x10 to 1x10 as the 2x crank set left arm is knackered.
https://bike.shimano.com/en-EU/product/component/deore-m4100/FC-M5100-1.htmlI have seen this set which comes in 170mm & 175mm arm length and 30 & 32 tooth options.
what I would like to know should I go for 170 or 175 and 30 or 32 teeth
the rear mech can only do 11-36 I mainly ride forest trails
Thanks in advance.his
