I've been riding my 2021 Niner RKT and just love the bike but I'm looking at a second bike with a bit more travel. I had a Niner RIP but it was just so big and the slack head angle just killed my shoulder on the slower sections or technical climbs. I'm looking at the Trance Advance 27.5 but they are pretty hard to come by but there is a local shop that has a Trance X in a small. I really love the 29 inch wheels on the Niner but I want more suspension,but not something I need to wrestle around. I'm 5' 6" and 63 years old with bad shoulders. Any input would be appreciated.
