it would work 10 sp 11-42 with GRX400 shifters or the latest Tiagra 10 speed shifters. But not 105 or Ultegra 10 speed shifters.
the point is to not need a Wolf Tooth Road Link, because a standard road 5701 or 6800 rear derailleur will shift 11-42.
Hi All - jumping in here... so will the GRX 400 derailleur work 1x10 with an 11-42 in the rear? That is probably what I am going to use for my build. Will I need a wolf-tooth extender perhaps?
I would have to use a GRX 1x crank for the chainline correct? or that would be preferred?
Thanks!
