Hi everyone iam new on here and desperate to find the rite crank for my boardman 8.6 hybrid 2020.I have looked and found no match for my 48/32 crank 9 speed.Can i use a different size or convert?i need my bike to have my time away from wife.very much appreciate any help thanks.

Ps bought bike and peddle was miss threaded an worn off due to use.Tried aquring a tap but no joy.

So you just need a crank arm? On the drive side (the side with the chainrings) or other side?
