Any suggestions or recommendations on frame material. I am 6"1' and weigh 220 (hopefully to lose some wt., but we'll see). My present bike is an all aluminum Cannondale (R300) and I'm looking to upgrade. I rode 2,800 miles last year (solo rides, group rides, charity rides, etc.) on the old aluminum (no carbon fork) and it beat me up pretty bad. Looking to upgrade bike with much newer components. Carbon, steel, titanium, aluminum for a guy my size???? Would like to keep to a $2,200 budget. Any help?
