quick question although Im commuting im trying to get enough conditioning to do a metric in the near future. my normal commute is 19 mile or 13 mile depending on route.
would I get more cardio benifit by riding the SS??, though I seem to spin out and coast alot (69 gear inch , very Hilly) The SS is my old road bike lugged 531 frame /fork Falcon . 1992 nice and light
or should I keep riding my 35 LB 24 speed Full dresser cross check.
