I'm a few hundred miles into riding a stock Trek 7300 hybrid. I've gotten the seat height and seat position right where if feels good (front of knee over the pedal when at 3&9 postion, knee slightly bent at full extention). Yet I sometimes feel that I am 'reaching' too far for the grips. How do I know I've got the handlebars in the right position (front to rear?). What is the common measure to determine your reach? My bike has a 20" (51cm) frame. I stand 5'10' - 180 lbs with a 30" inseam and a 35" sleeve length. If I put a straight edge on the top of my saddle I can see that my grips are about an inch above my seat. Still, the front end of the bike occassionally feels a bit 'light'. If feels especailly light when I stand up to pedal. I don't know if that due to the longer wheelbase and lighter weight compared to my old moutain bike or not. I'm trying to figure out if its a different fee due to the bike design or due to an improper fit / adjustment.
Any an all ideas / suggestions are welcome.
