My wife is struggling with the 30t chainring on her new 2016 giant reign 1 so I am after an option that lets her use a 28t. The current crankset is a sram x1 1000 which doesn't allow for direct mount chainrings. I am looking at a sram gx 1400 instead. Will this just directly replace her existing crank? Do I need to make sure the spindle length is correct?
I have tried asking the local bike shop but they can't give me a clear answer.
Cheers,
Chris
