dont do it, do no get the medium. a small with a 90-100 stem will be perfect for your size. from my experience i can say trust the yeti sizing chart. im 5'6.5" and run mine with a 100 stem. killer bike....CAK said:Thanks! I'm assuming most of you are in the below to 5'6" range? Thats how tall I am. I had a chance to ride a medium with a 90mm stem and felt like my outside arm was stretched to its max on tight turns, made me feel a bit unstable. Nobody has a small for me to ride in SoCal so it's all based on numbers. Yeti says a small is my size and numbers wise it is comparable to my current bike but the smalls look really small. Just trying to figure out how close the toe overlap is going to be by superimposing one of your pics over my bike.
One thing you might want to consider is being in the middle of the bike would give you the best performance. If you get a small and put a 110 stem and a laid back seat post then you might want to jump up to the medium (the 575 tends to run a smaller cockpit than most other bikes). I am 5'7" and have a 29in inseam my bike before the 575 was a Psycle Werks Wildhare size XS and had to use a 110 stem and laid back seat post to get me comfortable on the bike this put my weight to far over the back tire and made my bike wander in the front on climbs. My local bike shop measured the distance from my seat to the stem and then fit me to a Med. 575 which puts me right in the middle of the bike (with a 100mm stem and Gravity Dropper seatpost) for better climbing and better handling and all day riding. However for steep and rocky descents I sometime wonder if a small would have been better because with a small bike you can throw the frame around a bit for technical situations. Also I was used to 9 in's of seat post coming out of my frame and not 6in. like I have now so asthetically it is taking some getting used to I sometime wonder if the bike was too big. But when I ride it all my doubts are washed away as I have plenty of standover height and the handling and climbing so much better than my XS Wildhare and Sm Gemini. The Yeti rep. said that I could have gone either way with the sizing but said the bike shop did the right thing in fitting me in the middle of the bike.CAK said:Wow, thanks for all the responces. Yep, looks like small is the size. Now I just have to order the dang thing
