I feel like i need a lighter bike.My ride back from Oughtershaw -Buckden has tickled my need for a bit of speed.Now their is nothing wrong with my fave Dawes Galaxy .But it would be nice to see how i would zip along these nice Dales lanes.I have a 64 CM frame on my Galaxy.I have spent the past week looking at various bikes.But i am confused with all the various sizes.58.5.61,63.I am 6'4" tall and have an inside leg 34".Just drop me a few pointers as to which size would be better.I have looked at Fuji,Cannondale ,Spesh.And Trek.Not sure at how much i can spend till early new year.Just want advice on sizing.
