Your TT position - pics

indjke

Now I look like that.
(Shot is made during training, I wear TT-helmet on races)
Is any good? :roll:

It looks like the seat may need to go up and forward a touch looking at it as it stands but I am no expert see a bike fitter for specifics.

Here's my position on my new bike. Can't get it any higher in the front without custom spacers, so may do that over the winter. It's actually quite comfortable but not sure about the amount of bend in my upper back.


This is my position on my old bike. I've since smashed that helmet so am riding with a Scott Split.

Grill, can you rotate your bars back at all on the Plasma?

Can you see up the road in that new position?

Grill

@mattclinton- Good spot. The stem hasn't been tightened since there's still a bit of work to do so the bars rotated down when I put weight on them. The bullhorns will be on a zero plane when I tighten them.

@LegendLust- Yeah I can see just fine although my neck might give me issues on anything over a 50. I'll have to take it on some long training rides to be sure.

You can get off the shelf spacers for the Pro Missile bars I am pretty sure, so if you wanted to come up you could do.

Yeah, but they don't add much stack and I can get the Fibre-Lyte ones for less.

OK cool, you shouldn't need too much stack anyhow, but I do think you are perhaps slightly too low with no stack.

Grill

I'm using all the supplied spacers so am at 50mm stack. I figure if I went for a solid 50mm from Fibre-Lyte then the additional 50mm would offer plenty of adjustment. I'm actually quite comfortable in the current position with the exception of my neck after a while, but I figure with training over winter I'll manage to get used to it a bit more.

When it comes to the super pointy helmets - I'm not convinced by them. Whenever I see anyone riding who is pushing hard or on the edge their head seems to drop sending the point skywards into the air.

Surely for many, a lid like Wiggo's would be more suited?

Now I have a kask bambino, and use it a lot, but here is a photo of me at a full on effort, there are plenty of us that can keep the helmet tail where it ought to be

The Bambino is simply fashionable, but it's not the fastest for most.

I got some aero bars that replace the handle bars for turning a road bike into a tt bike.My question is,do I use the same size stem as on my road bike(100mm) or start bigger or smaller stem.
thanks

Grill

If it's for a road bike you should go smaller to try and come close to TT geometry.

elderone

Tks Grill for quick reply.Any tips how to get my seat where it needs to be.Looking at all the pics in this thread the seats seem a lot further forward.Is there a method to work out how far forward the seat needs to be.
cheers.

Grill

Minimum inline post although there are some you can get that will give you a positive offset. Saddle jammed forward as well.

elderone

thanks Grill,will look into sorting that then.

greg66_tri_v2.0

I did not know this thread existed!

Anyone care to have a look at this: http://youtu.be/8z5jHN64xF8and throw me some pointers? Anything and everything gratefully received.

Background: I'm not a TTer. After a break from tri I returned to it last year, riding an S2 geometried Cervelo, with a flipped seatpost head and the front end that's now on the P3. I've just (within the last couple of weeks) got the P3 and am still setting it up. If anyone's interested, it is a bugger to cable.

In the vid I start on the mid/front of the saddle, then move all the way to the tip of the nose, then finish back where I started. There are two freeze frames at top dead centre for each position. On balance I preferred the mid/front position.

Remember I have to run off this, so I guess I'm looking for aero tips using a mark I eyeball rather than a wind tunnel. It's early days on this bike. I've spent little more time on it so far than you see in this video. It's been a slow build...

TIA

Here is my old road bike converted for TT,s.I have read this thread inside out to get pointers on set up.What I have tried to incorporate into my position is every thing I think is good to get my base set up
In this position I have done 2x20 on the turbo as a tester and I found I was able to complete it at threshold whilst staying in position .
I have all winter to train for next season and make adjustments if needed.So from the pics am I in the ball park
position wise.



Thanks for any advice offered.

This isn't meant to be a critisism in any way. Please try to get a position where you are looking ahead and that means getting your neck muscles used to holding your head in that position.

You're too far back in the saddle as well, look at some of the pictures in this thread, they're nearly all on the tip of the saddle. And also remember that if you were riding with your head down on a proper TT then you could be disqualified, a lot of them are starting to crack down on cyclists riding with their heads down because of previous accidents.

I said you could, not will. That's a rule that been brought in for our club TT's and I hear a few others have brought it in or are considering bringing it in.

Grill

CTT doesn't deem it an issue, which is what's important.

elderone

Cheers lads, to be fair I didn,t think about head position as such when the pics were done.I was more concerned with the angle on my back and the angle my arms are at.I have now got a aero helmet and will do some more pics with the recommended adjustments.

I would appreciate opinions on my position in these photos. I don't think it's too bad but I'm always wondering if I can eek out a little more power of get more aero. Not sure if I should be getting my head a bit lower or whether the arm pads should be extended a little or stay where they are.

GBY73

Thanks for that(and yes, I'm quite into my TT's). I've actually started a program of core work in the last few weeks so hopefully that will help in due course. Getting too low too soon gives me lower back and upper leg discomfort. I did have a bike fit a year ago but had some reservations about the results, particularly raising the bars.

There was an interesting thread on the TT forum about low at the front not always giving the best CdA.

My concern mate is that bike looks too big for you! Also that your hands are too high, shouldn't you have parallel arms with the road and slightly upturned hands, if at all?

Sorry to be negative but remember Richie Porte is riding a 48cm frame this year.

pilot_pete

And to add to Bo's comments that your saddle looks too high judging by the almost straight leg at the bottom of the pedal stroke. Get a video of you pedalling from behind and see if your hips are rocking which I think they may well be with that lack of knee bend as you 'reach' for bottom of the pedal stroke.

I also thought at initial viewing that the whole bike just looks a bit too big; the top tube looks loooong and your elbow rests are a long way forward of your elbows, which is a combination of long top tube, stem length and base bar/ extension positioning.
