I did a basic “at home” fit when I built up my Scott Plasma TT bike in November, and I’m pretty comfortable on it. I’ve done quite a few long training rides on the Plasma, and I’ve got no serious complaints about my comfort on the bike.
Comfort is very important, but so is performance.
One thing I neglected to do after dialing in the Plasma’s fit was photograph myself from the side. I always felt like I was extremely aero on the TT bike–especially after I slammed the stem–so I guess it never occurred to me to actually check.
When I saw this photograph from Monday’s race, I was pretty shocked:
Putting aside the unfortunate fact that the photo was snapped while my belly was distended from deeply inhaling :|, my position on the bike looks less than ideal for my physiology. I am very limber, and so there’s no reason I should be riding around in the aero position with my upper body up high like that. My chest should be pretty much parallel to the ground.
Take a look at Tony Martin, arguably the best time trial racer on the planet:
I’m wasting power. I averaged 300 watts at Monday’s 40k TT race, and my time was 59m19s (25.1 MPH average). I think with that kind of power output I could (and should) have a significantly faster time.
I don’t own a Goniometer (I should probably get one), but looking at the picture from the race it seems like I could raise my saddle to improve my position and pedal stroke. I’ll take a look at that first.
I’ve already slammed my stem, so to lower the bars any more I’d have to go with a negative rise stem.
I’m a do it yourself kind of guy, but I really think a professional bike fit is what is called for. I know a couple local guys who are experts, and have all the equipment and knowledge to do the job right. Unfortunately my bike budget is blown at the moment, so I’ll just do the best that I can for now.
