Frame size help
Hello. I need advice with frame size for AM.
Bike: SCOTT Genius LT 20 Bike - SCOTT Sports
I am tried competitivecyclist.com and that's what I got:
All Mountain Fit
Standover Height Range 32.9 - 33.6 inches
Virtual Top Tube Length 22.7 - 23.1 inches
Stem Length 7.2 - 9.6 cm
BB-Saddle Position 73.4 - 79.5 cm
Saddle-Handlebar 51.8 - 53.6 cm
Inseam 88 cm
Trunk 69 cm
Forearm 33 cm
Arm 60 cm
Thigh 63 cm
Lower Leg 58 cm
Sternal Notch 154 cm
Total Body Height 184 cm
Dealer at my local shop says that I should go with L, because M seattube is too short and I can break the end of tube if I rise saddle too high, and 23" top tube will be too short with a 50mm stem. But I am afraid, that L will be too long for a technical ride and it will end up like a gate. And a worst part is that they can only order one of them for me and after I made a choose I should 100% buy it, and also there is no return or exchange. And also no way I can try them...
I don't know all mountain so that might change things - but I'd say a large.
Your are 6' 1/2" with a 34.5 inch inseam. I'm 6'1" with a 34 inch inseam and ride 19.5 or 20 inch 29ers. I have a drop bar bike I purposely ordered with a 18 inch frame to reduce the reach and I use almost all of a 410mm seat post on it.
A 26er will have a lower bar height than my 29er - I can't imagine how low the front end would be on an 18 inch frame.
Your dealer must have other large and medium bikes you can try to get an idea how they will fit.
Maybe someone else with all mountain experience will have an opinion.
Thanks for reply. Will try bike with BB/seat tube that equal to M and will see how it will be. L has longer top tube (by 2.5cm) and seat tube (by 3cm). My experience with full-suspension bikes is near zero, so it's hard to realize, how that difference will affect ride.
