Well ive decided to spruce up my old bmx racer and go get some laps in on the local track, maybe some casual racing. It's a mid 90s dyno nsx. 44x16 gear and a 17.5 TT. I'm just under 6' and I realize this is small for me. I ride an undersized road bike for criterium races and wonder if this 17.5 TT frame will be fine for me.
Technically I'll be saving some weight with a smaller frame, what are the cons to me running a kids sized rig instead of a 21" TT like I should.
TIA
