I bought a Wahoo about 5 or 6 years ago and I really wanted to trust my LBS since the next closest one is in Annapolis which is 30-35mins away and only sells Specialized. The guy that was in there seems to be the owner of the franchise because he's the only one there whenever I go in. He's slightly shorter than me with shorter legs. Anyway, he sold me the Wahoo with the claim that the 17.5" is what he rides and it felt about right when I test rode it but once I got it home and had time to really ride it, nothing felt right. He also didn't spend anytime to make any adjustments once he sold the bike. The bike became so uncomfortable that I sold it just after a month after I bought it(back hurt, felt like I was leaning forward too much, feet were coming off the pedals slightly, etc). I was more comfortable on the $100 k-mart special I had when I was 12!
So, after doing some research and lurking through some forums, I came across the link above which seems to be fairly comprehensive enough to get me closer to what I "should" be looking at. I want to get back into riding again and I've been looking at 3 mountain bikes at around the same price range(hardrock sport disc 29, Trek Marlin, Trail 5 29). The strange thing is that some of the measurements put me on a 15.5" or Small and then the others put me at 17.5" or Medium size bikes.
I know it's more about what is comfortable but what should I do when you're have trust issues with your LBS?
Anyhow, if it helps, my measurements and what the above link spit out are below:
Inseam 29 in
Trunk 23.5 in
Forearm 12 in
Arm 23.75 in
Thigh 23.25 in
Lower Leg 21 in
Sternal Notch 55 in
Total Body Height 65.5 in
Standover Height Range 27.7 - 28.3 inches
Virtual Top Tube Length 22.1 - 22.5 inches
Stem Length 8.6 - 10.2 cm
BB-Saddle Position 64.4 - 65.9cm
Saddle-Handlebar 48.4 - 50.0 cm
Thanks for any help and advice!
