Set screw is starting to round out. Can still turn it but getting allful sloppy. Does anyone know part number from Shimano to order or if you can't order what size is it ?
Also this is 3rd Di2 install and for some reason cannot get front deraileur to not rub when in large cog and big ring. It trims fine but just not quite enough when in large cog (23), fine in 21. Never had problem withthe other 2 installs. Is there a trick I'm missing ?
