I've had a 2016 stumpy for years now, still going strong. This winter I wanted to upgrade the drivetrain to a 12x1, were you able to get any guidance from your post or do it yourself? Really interested to learn more.
I went with the E Thirteen 9-46 11 speed cassette. Much cheaper than upgrading to a 12 speed and the range handles everything I ride and I climb a lot.
