So i am new to cycling and am not sure what frame size i should get. The 15 frame the height is good but the length felt a little short riding it. The 17 frame when i stand over it. I hit the cross bar but the length felt good riding it. The store told me to go with the 17 but another told me to get the 15 and change the stem and something else to get the stretch. oh yeah my inseam is 29 and 5'5. Any advice will be appreciated. Thanks
