As per the subject, had change my fork to rigid, 1.5 tyres and getting light frame MTB. Currently using Shimano XT, the crank with 4 spider hole. It is possible just change the plate to 50-54 teeth? Currently 2x10 speeds.
Any shops doing it, if yes around how much the cost? Thank you
Most MTB frames won't fit 50T+ chainrings they wont clear the chainstays. Also most road chainrings are not available for a 104bcd 4bolt mtb crank. Plus a 44/11 is good for 50kmph+ Before spinning out, pro level maintaining that on an mtb with 1.5" tires and a flat bar. Just putting a bigger chain ring on will not make you any faster in my opinion.
