Stalkan is correct. Tony's reach is limited by UCI regulations to 75cm without an exemption, or 80cm with an exemption. In his case, his saddle is sufficiently behind his bottom bracket to allow for him to take the reach exemption, but it still isn't enough. We have women who are 5'2" who take the reach exemption. In fact, virtually every pro takes the reach exemption. In the end, we need more reach; the UCI will give us 10 degrees of seat angle (who needs that?), but no more reach. Drives me crazy.

Our club nationals, here in NZ, are run under UCI rules (at least for the past 5 years) and the 75/80cm reach rule catches people out every year. Guys hacking off their extensions, cutting down the levers on their shimano shifters, removing shifters entirely, tilting/rotating bars, adjusting seats frantically just before their TT start times.

I just don't understand why the rules are so tight just to prevent the outlaw positions.

Jim, how do you figure Brad Wiggins and Taylor Phinney get around the reach restriction? They both look fairly "laid out" and not at all cramped like Tony Martin does.

If you're 190cm or taller you get 85cm of reach. It's a bit ridiculous to have the cut off at a fixed number like that though.

I blame today's mfr's and yesterday's enthusiasm with seat tube angles and the amour de low. At 1.83m tall and on one of my TT bikes, I can get ~90 cm reach and be completely UCI legal without an exemption...but, I don't have any skin in this game, so YMMV.

Doesn't look within the 10 cm window for the pad-tip of extension difference rule to me. I wonder how they figure it is UCI legal?

Do you mean that you don't get any more aero if you stretch past the UCI reach limit? My experience: I don't know any elite TTer whose CdA doesn't continue improving until they take at least one UCI exemption.

And, yes, we make darned sure there's no saddle-hopping.

It probably depends what the measurement points are. I recall a picture of the UCI rules where it's stated that all measurements are taken from the front of the pads. But perhpas somebody knows it for sure?
And it probably also looks more (due to his rlbows being lower still) than it really is.

There is no rule to hold the measurment point at the end of the extension with the hands.

The armpad drop measurement is taken from the lowest point of the top of the armpads.

I'm saying I can get ~90cm reach and be UCI legal without an exemption on one of my TT bikes. If you can find me a low cxa frame manufactured in the last several years with which I can achieve the same setup, I'd be interested.

I apologise, I may not be following the thread carefully enough. Just to be sure... you do mean, reach, as in BB centre to tip of extensions?

haha, not that I race TTs with marshals, but I'm exactly 1.9m tall. good to know.

where do they measure from?

Needless to say, as a BOP triathlete, when I did my fit w/ Jim@ERO the UCI rules were not at all a consideration.

Like any height measurement I imagine. Not sure how that whole process works practically though.. I'm 189 with a longish torso and long arms so I'm f*cked. I stopped doing TT's because of how they measure reach to the shifters now when I don't get the 85cm of reach.

From a CxA perspective, if I was trying to easily quantify how stretched out a rider was, I would use terms like reach and drop...and I wouldn't define reach as the UCI conforming dimension. I can get ~90cm of reach and still conform to UCI regs without an exemption on one of my TT bikes - and I'm only 1.83m tall with about 8-10cm of drop. I don't think folks should blame the UCI for not being able to stretch themselves/their riders out - they should blame today's mfrs and yesterday's idea of "rotating around the BB" which fueled a disease of "lowness". If you are only 7cm behind the BB with a normal saddle at a saddle height of 80-85cm and you play by UCI rules, you should be saying WTF to your bike sponsor.

getting back on track here..."High hands" where the center of rotation is not the elbow, is just another way of modifying the point in space of the elbow vertically and axially within the UCI rules (i.e, this rotation effects how stretched out/low the elbow is)...so why wouldn't one explore it?

IME, if you control for elbow position vertically/axially, cxa doesn't change much - just for fun check out this vid I did moons ago:

http://www.biketechreview.com/images/the_shrug.wmv

you can do all sorts of crap with your hands/forearm angle, but if your elbow doesn't move much vertically/axially, how low/stretched out your torso is doesn't change much.

So from the back edge then?

on the recommendation to add reach--are we talking about moving the pads further out or just the extensions? or both?

I'd be interested in these as well... what did you pay?

For those with a fixed position on the extensions, these extensions from Zipp should give you enough rise in the hands:

I just went to get fit for an IA16 and I brought the extensions for the original CarbonX. They give 13 cm of rise. The old extensions are going on the new bike.

OK, so i'm looking at this and i don't understand how this works. are you using everyting stock? bars, spacers etc? I guess i'm missing the holes where the pads attach. can you possibly post some more pictures of how it all goes together? I have a SHIV TT as well and i'd love to angle my pads up.
Thanks!

Street by street, block by block!

This thread, and the ERO post was really helpful. I just had a professional fit done on my (relatively new) P5-6 and wanted to try the angled arm position. We swapped out the standard extensions for Profile T4s that were inserted backwards. Using spacers, we angled the pad holders up, not quite identical in slope to the extensions, but enough that you can really feel the support you. We added reach, and moved me to a bit more slack angle than I was before. Only two rides in, but this position is incredibly comfortable. The angled arms really do allow you to lean into the bars, supporting the rest of your position and allowing for a more relaxed upper body.

Per this thread, I am ordering angled risers from Fibre Lyte. One thing I am going to add are some rubber washers between the bolt head and the armpad cup. They hit at an angle and I would like some thing there to deform and absorb a bit of the stress.
