I run a 40t 1x w/an 11-42t cassette on my gravel bike. I am fat and old. I've read that a 42t cassette is max w/the GRX812 rear der. - but some run an 11-46 with no issues? Internet stories.
Any experience w/a 1x 40 by 46 in the rear w/a GRX812 der?
I was thinking a 46 or 50 in the rear; do I need to go w/a
Road link DM?
