I’m 6.3 and also felt the large Tracer to be a little cramped at first. I swapped the seat post, now using a RF XY (set back) before that I was using the RF X0 (no set back). This made a big difference for me…….the bike felt a lot better with the set back post. After swapping the post I did not feel the need for a longer stem (stem is a 120 mm 5 dgrs and a low rise bar).
Maybe you should borrow a set back post from your LBS so you can feel the difference it makes. You might also want to try different stems then.
I just made a tour around the Mont Blanc on the Tracer and must say that bike still rocks (I had not been on it for quite some time). Long climbs on tarmac, steep climbs on gravel and nice twisty trails down………this bike still is yum, yum to me.
Happy trails,
AJ
