This shows the tolerances better:
Thanks. THose are making me think my reach is too short.
This video is probably the best shot of MEA in the aero position. It is on her track bike but that is very close to the TT bike. She makes this look easy. We show the start of the 10 lap effort and then pick up the action at lap 6 or about 32 mph.
We are trying to get her to keep her head down. You will note near the end of the video as the motor is doing 37 mph, she drops her head and slightly rotates forward as the effort gets really hard for her. We would like that all the time. However, she has a great position, flat back (not rounded) and great neck flexibility.
I hate young fit women. Just sayin'
What I've sort of figured out for my TT position is that I need to set up my bike at the UCI extremes and then adjust by millimeters from there. My extensions are in the 5 cm gray area and my Ares saddle is right at 5 cm behind the BB center. From there I play with the elbow pad height and saddle height (within a few millimeters of my theoretical ideal saddle height. Of course, YMMV (by a lot).
Given that most (but not all) really fast TT folks look about the same, you'd think it would be easier to find your ideal position. Clearly it's not. Very small changes have a big impact both on how aero you are, and how much power you can produce. The folks running the Faster wind tunnel claim it is extremely individualized, and that changes which look like they would be more aero often actually aren't. But then, it's in their interests to say things like that. The most aero rider they've had in the tunnel is one of the UHC guys. Second most aero is "Rocket Man" a teammate of mine. Many of the folks on the team have spent time in the tunnel, and nobody has complained that it wasn't worth it. The focus has usually been on the two biggest factors: position and helmet. You need a lot of experience, and the ability to objectively evaluate yourself, to be able to sort it out yourself... a' la' Ex.
I am way not in the UCI limits for the saddle, my saddle nose is 2 cm in FRONT of my bb center. I'm lead to believe at my height (5'2") it would be a no-brainer to get a morphological exception.... I haven't applied for once since I am a 4 and I doubt it will come up.
Key to passing the test is to sit on the saddle as far back as possible (a long saddle is desirable). However, if your ass is off the back of saddle, it is going to be a problem. I would not say it is a no brainer. I would say that your height will cause the commissionaire at technical inspection to want to grant an exemption. However, 2 cm in front is IMHO too much. It doubtful that you can sit normally on the saddle and have your knee in the proper position relative to the pedal spindle. And you are only allowed one exemption. If you get one for your seat then the aerobars must be in compliance and not in the grey area.
The other thing to remember is that I have only had my TT bike checked at Nationals. The first time I went, I thought my bike was in compliance, but it wasn't and I spent a couple of hours the night before the race getting it to be compliant. Of course, changing the position the night before a big race is not ideal. :rolleyes: Last year the bike passed with the position that I had been using all year.
If I wasn't racing nationals (or world championships) then no one would have ever checked my bike. Being a law abiding engineer forces me to be anal about my bike's setup.
I need to read what the setup should be. Next, I need to get a saddle for my Felt that I can actually stand for more than five minutes, and then take it out and ride it. And THEN start getting it dialed in. It NEVER has been, and I've owned it for two years.
just registered for my A race. THey sent the notice that reg was open today, so I went ahead and registered. I was the first one, and they were letting you pick your start time within your category for the TT.... so I'm going last. :innocent:
and of course now i think i should have gone in the middle. hmmmm.
The Racer Ex garage sale begins
Nice collection of stuff.
I'm gearing up for an ebay purge, as well... but it's all crap, compared to that haul.
Oh look you are selling an srm with 165 crankarms. And disk wheels. Hook line and sinker.
I did LT intervals on a local hill on my road bike today, my longest one (16.5 minutes) I had watts 15 above my mean-max for the same time period in my TT race last weekend, with HR 8bpm lower today.
