I'm a older guy in the market for either a hybrid or comfort bike. Early 60's, out of shape and lots of hills here where I live. I'm about 5'11" but with a 31-1/2" inseam. According to Hoyle, I should be looking at mid-sized frames around 17". It seems that the bikes I've tried, just straddling, all come right up to the crotch. Just sampled a Nishiki 17" comfort bike and a Diamondback 17" hybrid (can't recall the model names), and the top tube of each one made contact when I stepped slightly forward off the saddle. The guy at the store (in this case Dick's) said I should have about an inch minimum clearance. A Diamondback Wildwood with a 15" frame gave me good clearance but he said it would be mighty short. Is the old maxim of an inch or so clearance still valid with these new frame styles? Am I going to need a custom frame? Going to check an LBS tomorrow but thought I'd ask here first.
Thanks in advance!
