Does anyone know if GRX crank arms are the same on 1x and 2x? I have some 170 cranks which are the perfect length for me but they are 2x. Is it simply a case of bolt on the desired size of 1x chainring ?
Thanks in advance…
I'm pretty sure that it is a simple case of fitting a new chain ring. Try and get a narrow/wide chainring when you do. Helps to stop the chain from escaping.
