Well done AZT, I'd forgotten that Pooley is just the right size.

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.

They are nice to look at, though. :innocent:

Quite right. Let's have a bit of equality here. And there are old fit people who are worth a look too, I'm glad to say...

Missed this one. I'm riding the stock seatpost which has one of those ritchey adjustable tops, slid forward almost all the way. Between the seatpost and positioning the saddle in the clamp I could get another 8-10 mm forward. That hip angle thing is why I think I need shorter cranks. If I had shorter cranks I could go higher in back & lower in front without closing the hip angle any more.

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).

AzTallRider 03-06-13 09:54 AM

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 like boundary analysis. There are limits and it is good to know them. For example, triathletes have almost limitless leeway on bicycles and position since they are not sanctioned by USAC or UCI.

valygrl 03-06-13 10:31 AM

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.

There is no application for an exemption. At some races, typically certain championships, there will be technical inspection. The rider shows up with the bike and helmet. The inspector puts the bike in the test jig and your seat position will not pass. They then ask you to get on the bike. While you are sitting on the saddle, the commissionaire drops a plumb line in front of your knee and the front of the knee with the pedals horizontal must be at or behind the center of the pedal spindle.

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.

Wow thanks for that, I will check my KOPS

edit.... uh-oh.....

Cleave 03-06-13 03:40 PM

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.

sarals 03-06-13 04:00 PM

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.

valygrl 03-07-13 04:29 PM

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

jdon 03-07-13 04:58 PM

Nice collection of stuff.

VanceMac 03-07-13 05:04 PM

I'm gearing up for an ebay purge, as well... but it's all crap, compared to that haul.

valygrl 03-07-13 05:36 PM

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.

Going to have a complete Cannondale Evo and a track frame up fairly soon. along with another SRM.

Need to do the same too with a variety of items -- some new, some lightly used. Trick is making the time to take some photos. I hate auctions that use stock photos from the manufacturer. I'll wait until Ex is done before I do anything since I actually have one identical item and a couple of similar items.
