The more I think about it I don’t think it will mater to you what size you go with. Its a trade off either way, but the Trance is a different bike to the AX29 so your riding style is going to change to suit the Trance anyway and it will just adapt to the needs of which ever size you choose.I rode a Trance 29 M around, on paths and roads in London Ontario and I sat on a L Trance 29 and rode it around the store in Toronto.
There are big differences in reach between my bike and the M Trance 29. My M AX29 has a ~ 26.5" reach, the L Trance 29 has a 26" reach but the M Trance has a 25" reach and I think I notice. I could get used to it, but, I don't think I would want to put a much longer stem on the M bike to make up for the reach difference. I did not find the steering/handling slow. Possibly slower than my AX29 but not bad in any way, but again I was not on trails.
So I am not sure what size would work for me. I may actually risk losing the chance to chose a 2020 model and search for a demo in M and L to really try on the trails.
I had my size checked by the Giant tool in the store and apparently I am 5 foot 9" as I thought but my inseam is NOT 30" ...it is more like 31.5".
So now not sure what I will do but as above whould ideally like to test demo on trail. On a hill I did feel strange trying to climb steep on the M.
What do you think based on my measurements?
Anybody else 5' 9" with a 31-31.5" inseam on a Large?
