So, as stated I have just bought my first road bike (1992 Trek 400). This is not a fancy new bike, but I hope it'll teach me the basics and take some good bangings.
Now, to the crux of the matter. I am 5"7. I believe my inseam is like 29" 30" tops; long torso, short legs. So, because of this I did not feel so comfortable on a 20" bike, which is within the 20"-21.5" range that is recommended for me. I instead went for a frame where I have clearance of at least an inch. I found this in with an 18" frame. The question; Should I be aware of any adverse effects if I ride a frame which is not recommended by industry standard measurements. I didn't want a frame chafing my "boys" yet at the same time I feel as if may road bicylcists disregard any danger of crotch crunching. Should I sell this one off and get a larger "recommended" frame, and learn on that? Or, should I stick with what gives me clearance and feels manageable (i live in new york city and could use a smaller bike I could whip around). Will I get the road bike experience if I stay at 18"? Most importantly, DID I JUST BUY A CHILD SIZE BIKE?!?!
