Shimano grx 400 shifters and grx rx810 crankset with new chainrings 31 tooth 42 tooth and 48 tooth arm length is 172.5 comes with some 2 mm chainring spacers to get a better chain line with a double set up asking $150 and this is a bargain considering the chainrings alone are $160 just for the chainrings.. these shifters and crankset have very little miles like 500 or so, because I ended up switching my gravel bike to a flat bar 1x10 set up..very clean no scratches at all.. if interested please email or text thanks for looking
