I just bought a Motobecane Fantom 29 with a 15" frame. Since I bought it online I wasn't able to try the bike out before buying it. However, I talked to several bike dealers and they said that a 15" frame in a 29er should be the right size for me. My 26" mountain bike is a 17" frame.
My stats are:
Bike stand over height: 29"
The bike feels good when I stand over it. The problem is when I ride it. I can't get my legs any where near full extension which makes me feel like I'm riding a kids tricycle. My seat post is 11" minus the 4" minimum insertion gives me 7" above the seat clamp. I think I need another 3 to 4" in height to feel comfortable pedaling.
Can I get a new seat post that is 15" or is that just going to result in other problems? Or should I just return it and hope that a 17" frame fits?
