Hiya

I’m looking to buy a 2021 Giant trance x 29er. On Giants I’ve always struggled to find a good fit. I’m just shy of 6 foot with long legs short torso and longish arms. So on the Giant sizing i sit on the medium and large cusp.

When i tried both the medium I had to put the seat all the way back on the seat post head and I stilll felt like I was sitting off tthe back of of seat by about an inch. I also had my knees hitting the bars occasions. But the shop guy said when I tried the large he felt i was over reaching and looked like I was pulling my shoulder forward when turning. …but otherwise I felt comfortable on large and loved that I felt naturally over the centre of the bike when climbing. While on the medium I had to pull myself forward on the steepish climb.

Shop guy says he could but a 10mm longer stem on the medium but will that fix sitting my tendency to sit on the an inch off the back of saddle wth it jammed all th way back on the rails ??? I gather I’m not alone in my long leg/short torso dilemma
Shop guy has no bias to sell either bike out of self interest so i think he is really trying to do the right thing.

HELP !!!

Sounds like you know what feels right for you. Another thing to consider is that the long leg/short torso can be negated if you factor in long arms? Generally, shorter torso will point toward a smaller size bike. However many people with long legs also have long arms which bring you back to a typical bike size.

How about bar width? Wider bars will tend to shorten bike bike compared to narrower bars.

test ride everything. do not consider ordering a bike (sight unseen) until you've test rode it. if you end up on a medium, make sure the seatpost height is feasible--meaning the seatpost height meets both the frame manufacturer and seatpost manufacturer's minimum insertion depth.

It feels like you are over thinking this because of the shop guy. You felt good on the Large so go with it. Between different stem length and saddle position you should be able to get it dialed. I have longer legs than torso, but also my arms seem to match my torso more. I have gone back and forth between M and L sizes on a lot of bikes and can generally make either work unless the ETT is super long.

Yes i did let the shop guy mess with my head a bit. I went a large and its pretty well. I’m just putting on a 35mm stem and some 50mm risor bars to get the bars a bit closer in

Instead of 50mm riser bars you can also consider 12* rear sweep bars and/or using less width. 760 instead of 800 for example.
