TT position question

Posts: 5,167
Just getting to grips with sorting out a position on my TT bike. I gather that it is a good idea to move the saddle up a little and perch yourself quite far forward if possible. My question is, should you try to maintain the same position of knee vs pedal spindle that you do for the road bike? Or is it OK to have the knee slightly ahead of the pedal spindle with the crank at 3 o'clock?

Some people i've seen at TTs are sitting really far forward. I mean REALLY forward - it looks uncomfortable, especially for the region "down there". Personally, I like to sit further back than normal so it's easier to stretch my body out in an aerodynamic way. If I sit forward, to get my back horizontal, my head is over the front hub! I'm using a standard road bike for TTs though.
I don't make any adjustments for TTs/"normal" riding, as a lot of my "normal" riding is in a really aero/aggressive position anyway. I've always thought it's better to get your muscles used to riding in one position, instead of two, but i'm probably wrong, as all the professional riders do it.
I take it you've replicated your road position on your TT bike?0 -
The idea (as a starting point) is to rotate the whole body around the bottom bracket, so that you pretty much maintain similar relative position between the three contact points on the bike. Saddle forward and up (a bit) means bars come down and forward = lower head and flatter back, but similar hip angles when pedalling as your starting position.
Of course it's not quite that simple but that is a reasonable starting point if you have a good powerful roadie position originally.0 -
This is what I'm finding at the moment, particularly after all the helpful advice you guys gave me. I've improved my position for flat TTs, but was training on the mountain TT course I'm targetting and noted that a good position on the flat is a really poor position for getting power down going up 8%-15% gradients!"In many ways, my story was that of a raging, Christ-like figure who hauled himself off the cross, looked up at the Romans with blood in his eyes and said 'My turn, sock cookers'"

Ah, so in that case it doesn't matter if your knee is forward of the pedal spindle (on a plumb line test) becasue a line drawn through the pedal and knee will still intersect (ideally) at the same part of the body.Le Blaireau (1)0 -

Have you actually done any proper TTs?0 -
I found my TT bike quite difficult to get used to despite rotating my body forwards and that training in this position was the only way of adapting. As I am not happy training on the road in this position I put some tri-bars on my turbo trainer bike and found that I could gradually increase the time I could hold this position.0

I am actually more comfortable on my TT bike than my road bike, certainly comfortable enough not to get numb nuts even in a 12 hr TT at the weekend. The bike was set up exactly the same as when I do a 10m TT. I would get as comfortable a position as possible, whilst getting as aero as possible. If you are not comfortable, you might find you just can't do good times.
Training in a TT position is a good idea, as the body has to get used to the different riding position and muscles used in an aero position compared to a normal road riding position.0 -
Thanks for the tips - I have raised the saddle a bit (in retrospect, starting off with it 1.5 cm lower than the road bike was not a good idea) and it feels much better. Just getting some quality time spent on it will help. At the moment, I am getting a bit of fatigue in the arms and shoulders, and I have to say it is not particularly comfortable on the nads when I am perched on the nose of the saddle - though it certainly seems to allow me to put the power down. Also getting a few twinges in the glutes but that is an area of known weakness anyway, so I realise I need to work on a bit of stretching and strenghtening there.Le Blaireau (1)0

Yep, ride on it as much as possible - your shoulders and arms will adapt. As for the undercarriage, that usually requires a bit of experimentation with different saddles and a lot of chamois cream.
I prefer riding my TT bike to my road bike because I'm so much quicker on it. The road bike is fun and handles better, but it often feels frustratingly slow.Jeff Jones

Undercarriage can be an issue, since you cant rotate seat angle in proportion to body so tip (of seat) can make things painful. If you have this problem then the Adamo saddle might be worth checking out, it worked for me.

I thought I had my TT position nailed, but I've developed a strange habit of being cr*p on the uphills relative to my road riding (where I'm normally a decent climber). Has anyone got any tips on if/how my position might be causing it and how I can tinker with it some more?0

I have found it to be pretty good on fairly shallow "power climbs" - you seem to be able to use your ar$e/lower back muscles (or that's how it feels) to really push the gear up them. Anything steeper though and the aero position seems to be no good for me - but then again I am a big lad and not much cop on anything steeper than about 6% anyway
I can now look back on Jan Ullrich's Alpe d'Huez TT in 2004 with utter amazement - how he rode up there on the aero bars is beyond me.Le Blaireau (1)0 -

How did it go. By coincidence it was doing my first 100 with the same specialized saddle as you that convinced me to check out the Adamo.Martin S. Newbury RC0 -

TTers spend a lot more stupid money on a lot less useful stuff, no point having the best aero position in the world if you cant hold it because your knackers are smoking.Martin S. Newbury RC0 -

I would've said more like "uncomfortaly numb" than smoking, but I take your point!Le Blaireau (1)0 -

I started to notice it after 50 miles - at times it was quite painful and I'd need to get out of the saddle regularly. But then I'd settle in and be fine for a while. It wasn't the limiting factor I feared it would be.
What was worse was not having a bottle of water for the last bit. I had energy drink (half the recommended concentration) in my hydration pack, ate three zipvit gels (had another spare) but I started to feel quite queasy in the last 20 miles and lost 35W. Definitely needed that extra gel but also the water to digest it.

Great ride Jeff, stunning time. If you/Old Tuggo do get an Adamo hope they help. They are a bit different from normal saddles in terms of setup, theres a useful video on to help with this herehttp://www.ttbikefit.com/shop.html/#adamovidMartin S. Newbury RC0

Will get an Adamo in for testing asap and post a review on BR.
And keeping this thread vaguely on track, if you're serious about TTing, you have to do as much training as possible in the position. To that end, I did two rides of 100 miles on the TT bike in the last month, so I had a reasonably good idea of what it felt like.
Ditto any tempo/interval training. Make it as specific as possible.Jeff Jones

Many congratulations, Jeff. A fabulous first 100!
Are you looking forward to the British TT Champs now? Should be an absolutely cracking day............

get an adamo road saddle. The first 5 miles of the first ride you do on it hurt a lot and it feels really wide but stick to it and after a few more rides you get no numbness or pain and its perfect. Its great for getting on the tip in time trials. i highly recommend it0
