Unboxed my brand new Boardman Adv 8.9 gravel bike yesterday. However the gears were all out of whack
I took it to the bike shop who set them up much better but there’s still rub in the first top 4 gears in the big ring (I know not to use the largest anyway for cross chaining), and the first 5 gears in the small ring.
The group set is the shamans GrX 400. When I get to the 5th gear in the big ring it’s totally silent. Not sure if I should take it back again, or if this is a simple tweet I could do at home?
Any advice welcome.

You know about trim positions?
