I don't know about you, but I don't need a gizmo to tell me that what I'm doing hurts and I need to go faster. :P

Ignorance is bliss until they take your bliss away.

If bike is already pushing the minimum weight limit, not that big a deal really.

The data is good to have.

As for watching it, maybe in the opening minutes to keep a lid on it so you don't blow early, then after that just run what you brung.

I would use it for post-race analysis and cover the display so I can't look at it during the TT.

I would DEFINITELY ride with power. The shorter the timetrial: the more usefull power is for pacing...

10.8k = 6.7mi for us 'mericans accustomed to miles instead of kms...
At 12mph, that is 33-34 minutes.
At 15mph, still 26-27 minutes.
Plenty of time to go too hard early, blow and lose lots of time in the second half. if you have power to pace by, use it. If your target is 300w, throwing down 350w in the first minute is bad pacing.

As others have said, for anything over a kilo, unless it is your 30th or 40th time racing the course and you have similar conditions with frequent time check points (like a pursuit on a 250m indoor track) use the PM.

For a TT effort that short, the powermeter will help keep you from going out too hard which would be the kiss of death. The extra 108 grams would cost about 2.5 seconds on a 10% grade over 10 km, right? My math isn't so reliable.

Starting too hard on this climbing TT is no doubt a great risk. Particularly when you just turned 16 and after three stages you are close behind a former TdF stage winner. Sometimes, something more objective than a voice on your head is needed when you want to get even ;)

So it stays on.

Thanks to all.

PD Shortie aerobars or not for the start of the TT at around 5% grade? They will also serve to position the Garmin in an easier to read position.



I am sure Tom Demerly can comment on this pic ;)

5%? Aerobars absolutely, not sure about shorties, can you get them mounted under the bar? I assume you don't need to follow ITU rules here, why not a TT bike?

5% just for the first 2 km, from there it gets way too steep. It is UCI rules. Using a TT bike is not the best choice for this particular stage, particularly with the grips of the Ventus bars.

Ah, I see, if the minimum grade is 5% then a road bike may be in order.

I assume you've got the bike down to 6.8kg w/ the clip ons?

I still have time to set up a R3 frame. I have no idea about the weight, but I am sure it will be below 6.8 kg w/o the clip ons.

Some good (or not so good) examples of clip on use on climbing TTs.
Ulrich using clip ons http://www.youtube.com/watch?v=CpPWTaE-0gM

Lance w/o them and Basso with them installed but not using them http://www.youtube.com/watch?v=7snz7jsQ__E

By the way the TT mentioned looks as steep as the AdH, shorter but no doubt as steep.

It is going to be a very interesting stage. I am glad they set up this ITT at the end of this stage race.
