Decent skinsuit. Pin your number down better.
Gurn less? Do you think skinsuits make much difference over well fitting jersey/ bib combo? Normally let a team mate put number on so that's an easy fix.0 -
Yes, skinsuits make a massive difference.English Cycles V3 | Cervelo P5 | Cervelo T4 | Trek Domane Koppenberg0

Nice. I will try it on the next training

My first TT bike and have settled on this position. I can keep in this position for about half an hour but it does ache my shoulders. Do I need to adjust it or just get used to it? Any adjustments I should be making?0 -
That could well be the same bike I was thinking of trying to get from the bay. Down South somewhere? Good low position BTW.0

Yep that was the bike on eBay that you saw. Still waiting to do my first proper event in the bike but have done a few training rides. Made the bars a bit wider as my elbows were nearly touching each other. Fell more comfortable now. Got a lid and skinsuit now too.

This is an impressive TT position, reminds me a lot of Wiggins position. If you can produce power like this I don't see any reason to change.0 -
1st few tt's this season. Any time saving advice welcome.
Good esp for a road bike but your reach seems a bit cramped and as such frontal area a bit upright. I suggest a slightly longer stem would help0 -
Longer stem and/or drop a few spacers...0

For those who have not seen it, there is a really nice video of TT position comparisons using wind tunnel and with CDA data on screen here https://www.youtube.com/watch?v=1vjm3DgBxvg0

.260 (which is ridiculously high) to .255 (which is still ridiculously high) on 7 runs? That is an embarrassing drop considering the starting CdA. Not even going to say what my starting and finishing CdA was after 3 AeroCoach sessions...English Cycles V3 | Cervelo P5 | Cervelo T4 | Trek Domane Koppenberg0

I'm as aero as a barn and started at .245, got down to .235 in one Aerocoach session just by changing helmet and 5mm adjustment to front end. That seems very high.Insta: ATEnduranceCoaching

Cheers. Now got a TT bike though so I'm tinkering with fit. Once somewhere near I'll put photos up on here.0 -
Think my position is ok, go ok on flat TTs but struggle when it gets hillier0

Your lid is costing you time as is the lack of shrug.English Cycles V3 | Cervelo P5 | Cervelo T4 | Trek Domane Koppenberg0

I've reduced my CdA enough to save well over a minute in a 10 with only helmet and skinsuit choices (neither of which are pictured). The difficulty is that when your position changes then you'll need to test again as what was once fast might no longer be the best choice.English Cycles V3 | Cervelo P5 | Cervelo T4 | Trek Domane Koppenberg0

What skinsuit reccommenations do you have for a TT'er on a budget Grill?0
-
On a budget go used. Lots of stuff on Timetriallingforum. Castelli and NoPinz are a good place to start.English Cycles V3 | Cervelo P5 | Cervelo T4 | Trek Domane Koppenberg0

I did my first tt the other day and my position looks a lot different when racing! It's difficult to see but should my saddle be more forward? currently my saddle is all the way back but it seems to fatigue my quads too much when forward?

Another view from a more recent tt. Head has come up as the surface was terrible but any other comments on my position?

There's no 'should' - what works for you might not work for anyone else, we're all different. You have to find the position where you are fastest i.e. the best compromise between power output and aero.
But yes, definitely try moving forward as you are quite far back at the moment. For reference, my bum is usually just in front of the trailing edge of the seat post.0 -

You should get your back flat. Right now your hip angle is off quite a bit. Your pelvis is angled too upright. Pelvis is basically how you would ride a road bike. Your internals are pushed together hindering your digestion (for longer timetrials) and breathing. Also the elbow angle is too big but that would fix itself when you rotate your pelvis forwards.
What you should do is sit upright on your bike (straight up) and then fall slowly forward moving the body only from your hips, meaning that the pelvis rotates forward and the upper body position remains the same and fixed with the pelvis. Good thing to test that is that the distance between your hip and your shoulder, should be exactly the same as you are sitting upright or in your aero position. Basically you should get the red line into the green line (
). Naturally, this would mean you have a TT specific saddle. Otherwise you just crush your nuts turning the pelvis forwards. You should be sitting on the front of the saddle tip right behind the crown juwels (hanging over the front).
My two cents.0 -
Also, if you get your back flat from rotating the pelvis forwards, you can lower the front end just a bit and the gap between you helmet and you back should also disappear. The long tail TT helmets work only with a perfect position. With a bad position you would be better of with a aero road helmet.0

You should move yourself forwards on the saddle and also move the handlebars forwards. You are much back to really put the power down. Half of your saddle should be basically unused and sticking out the back.

Wow thanks for the replies. I have always thought I was a bit too far back and moved the aero bars back from where they should be. I'm going to move both the saddle and bars forward and see how that goes. I think it comes from all my time being on a road bike. But really enjoying time trials so far!0

This simply isn't true. Triathletes need to save hams and glutes for the run, testers don't. The only reason to not use all of the power your legs is if the drop in CdA of a less efficient position is greater than the loss in power (and the only way to know this is to test). My position is quite far back (farther than on my road bike) and I'm very aero. Basically the only way to know what works best is to test.
You need to work on your shrug. If your position is shifting so much from the turbo to the road, then you need to train to the heart position or change it.English Cycles V3 | Cervelo P5 | Cervelo T4 | Trek Domane Koppenberg0 -

Sorry can't work out how to post this as an image but a couple of pictures of my TT position in link above. Any thoughts? Looks like I maybe need to move bars forward a bit, and get my head down!0 -

Tbh, the big issue isn't back this, saddle that, it's the helmet. From that photo I'd wager it's actually slowing you down. It should flow into your back, that's going to be creating a massive wake. I reckon your position otherwise looks ok.Insta: ATEnduranceCoaching
