I dont know if accurate but on the kgf instagram live video Tanfields 3000m split was given as 3.07...That is well inside world record pace. Maybe explains the catch - I was a little surprised he sat up afterwards maybe went out so hard the wheels were about to come off!

Of course i may have misheard the 3.07

On these pursuit positions, isn't there a UCI rule stipulating the forearms have to be horizontal, not tilted up or down?

I believe that the upward extension of the aero bars is allowed to be 100mm above the elbow rest. so about 4" (102mm).

they changed it a few years ago (again) and you now have some leniency with tilt.
Basically... so long as you keep the pads to the tip of the extensions within the 10cm limit, go wild. And since most jigs measure a flat plane on the pads, you can "cheat" the system if the pads are angled as well because the top of the pad will be considerably higher than the "middle" of the pad.

Yeah I knew UCI relaxed the rules a bit a while back to allow more extension rise, but his sure looks like a lot more than 10cm. I guess it must be measured from the highest part of the pad, he's got those pads tilted quite a bit so he's probably gaining several cm compared to if you measured from the back or from level pads. Definitely not a typical/old-school pursuit position, looks a lot more like a TT roadie or (gasp) triathlete far as narrow elbows, high hands, etc.

All the jig's I've seen just have a flat piece that is supposed to lay flat on your pad (to take the 10cm measurement)
If you're pad is angled at all, it can't lay flat on it and instead has to lay on the highest point. The real restriction (considering mantis style positions are good for you aerodynamically...in my experience they are usually good up to a point, then terrible, although with consistently lower yaw indoors it might be different) is keeping your extensions below your saddle. A lot of guys are cutting that VERY close...but I don't know if it's something that comm's actively measure or not. (yet)

I didn't know there was a rule about extensions having to be below saddle. Hard to tell from pics how much extension is under his hands, but it looks like they're at least even with the saddle.

it's an obscure way of making sure you don't try to run the Egg position I believe.

It's annoying because this position tested pretty slippery for me.

By the way one of the most common rules that is ignored is 3.2.003 " In addition, while riding on the track, riders shall at all times be in firm control of the bicycle and have at least one hand on the handlebar (or extension)."
Both hands up in the air is quite common in World Cup events.

Article 1.3.022 in the clarification guide, this diagram shows the limits of handlebars. There is no later diagram related to TT/Pursuit specific positions related to the rest of the frame (like this one) so this one seems to be used.

Stumbled across this bike in a classified ad. Back half is a BT, the front half is done by Roberts Composites in Vancouver, BC. 62-63cm TT on this bike. [IMG][/IMG]

isn't there an arm-angle rule, too? or did that expire? i can't keep track of the changes.

^One of the good changes that's been made the last few years is that you no longer have to be measured on/with the bike. (From what I understand it was so mechanics for pro tour teams could bring the bike without the riders having to bother themselves with being there standing in line) You get 1 free exemption (-5/0 seat setback or 75/80 reach) regardless of how tall you are. (You can still apply for the bonus 5 to reach if you're really tall, bringing it to 85) So for the most part, things like arm angle are gone.
