have to say RC, I am surprised by your intial post as fore/aft seat adjustment is the first thing any fitter does to ensure proper weight distribution and moving the seat forward or back affects reach to the handlebar and utimately stem selection...what Shane is trying to tune. Shane, every once in a while the board troll incites a thread which is more comedy than anything else. Connie, you know biking and are keenly aware of ergonomics having suffered with hand pain. Defense of what you wrote doesn't even deserve your time. Many forums have trolls. It depending on the guardianship of the board sponsors and sadly the policy here is laissez-faire which taints an overall friendly group of enthusiasts...his objective BTW...to spread the hate he feels for himself which is too big a burden to shoulder for a coward.
Shane, by the sound of it, to put your mind at ease, you bought the right size bike. From here, its a matter of adjustment and getting your body conditioned through long road miles. As mentioned, the first thing you want to establish is KOPS...not an absolute but a good reference point for establishing your reach to the bar. KOPS is a guideline only and largely determined by your cycling intensity. Leisurely riders typically prefer 1 cm or so behind pedal spindle to promote their weight back a bit and more aggressive riders like knee position even or a bit in front of pedal spindle. This will establish your CG intially of that big body of yours on the bike. Then you dial in stem reach and rise presuming you are on the right size bike which you are. A comment about your proportions. Sounds as though you provided your pant inseam at 34". I am 2 inches shorter than you at 6'1" and have a 35" cycling inseam, i.e. PB to ground and ride almost the same size bike with a shorter reach stem with a bit of rise. You may have an inordinantly long torso, but suspect you didn't state your PB to ground measurement, as 34'" though not impossible, would be short legged for your height. In any event you should have no problem with your top tube length and subsequent dialing in of aggragate top tube and stem length on a 62cm bike with your size, in particular if you are mostly torso but even if you aren't. Keep in mind you will stretch out as you accumulate road miles. PM me if you want freedom from any further inane chatter.
HTH,
George
