Acceptable power loss
Postby toolonglegs » Fri May 23, 2014 2:47 am
I think my position needs some tweaking as power is fair bit down on what I can hold on the road bike. Probably about 7 or 8 % down. The position seems pretty fast, but if I could modify my position a bit and gain another 30w from the legs it wouldn't hurt ( well it will hurt but you know what I mean ).
Or maybe I just need to spend more time training in this position ( which is comfortable enough ). Only spent about 20 hours on this bike so far.
Anyone got any comparisons?

Really you want highest W/m^2 (i.e. speed), so if you have anyway of field testing your aero drag...
I didn't lose any power on my TT bike. Most of my TT clients over the years didn't lose much either. Occasionally some would be down 5%. 10% would be a lot IMO.

I don't think I am too far off and probably just need to train the position a fair bit more ... and myself too!.

I notice I struggle to maintain good power on the flatter / slightly downhill sections... I don't spin long cranks all that well obviously!.

Not going to stress over it too much, going to be away from home much of June through to early September with only a road bike and mountains to ride. Not ideal TT training for September, but I am aiming to improve my aerodynamic drag by huge amounts in the next 3 months .

I'm exactly the same (on long downhills) and it frustrates me no end. If I could TT all day on a very slight uphill I would be a happy man.toolonglegs wrote:I notice I struggle to maintain good power on the flatter / slightly downhill sections...

I could never spin past about 110 on Q rings as I'd just start to Bob and become uncomfortable.

I had many moons ago a set of Rotor Power Cranks ... They had a cam set up and actually accelerated the crank through the 12 o'clock position... They were heavy and had too many moving parts.
If I could find a cheap set of 180 Oval cranks I would give them ago.

I don't do much in the way off core workouts... Mainly stretching. I'm going to try and figure out why I can hold much better power on a gentle climb or into the wind... But not today, felt great in yesterday's race... But hip flexors have ached all night long.
Slow today!.

But on the cadence side of things. I see alot more people are starting to run alot higher cadence in the TT's 100-110 range. Noticed this with the NRS/mas A/Elite A riders at the Battle on the Border TT and the Ippy TT

My legs would burn but the lungs and heart were comfortable. More time on the TT bike perhaps... I'd love to pull 5% losses or less, need all the watts I can get!
