Yeah, but they hold the shoes to his feet.

On second thoughts surely the laces cause more drag than the trips save?

Get the new Specialized Sub 6 shoes, they have lace covers.

Has anyone got a Campagnolo Aero seatpost bolt and square lock nut for sale?
Mine snapped and I couldn't find it on the road. Ripped my jeans but not flesh.

I've seen a CFD aero heatmap of a bike & rider (same position and viewpoint as below), demonstrating how the rider contributes most of the drag.

I can't find it now: can anyone else?

Nope.

Thinking about it, it might have been a from a more head-on angle.

Off topic but could someone make a bogus bike computer with a powerful battery and with fake sensors connected to the wheels acting instead as an electric motor, repelling the magnet on the wheel everytime it gets past? Would it be any good in time trials?

Slowing you own as the magnets approach each other?

No that would not be a good thing for time trials.

An Electronic motor that fits in the seattube, and engages the crank axle is the way to og.

my garmin gloves arrived this morning, the glove part looks like it might fit, the wrist bit however only fits 2 fingers in...

No, a wheel mounted motor in your disc is the way to go for TTs, you can put the battery in there too and if you use a torque sensor between your sprocket and hub shell you can get it to do regenerative braking into the turn and only use the power boost on the hardest parts, where the gain is most useful. Not that I've spent a lot of time thinking about this...

I think they mean electromagnet that acts like a rail gun, sort of timed to help rotate the wheel. That's what I assumed anyway. Given the power you could get from it I think I'll stick with eating pies and pedaling.

Now you know why they test fast.

Isn't that exactly what the Denmark Wheel does? Which would take about 15min adding a set of aerojackets to.

Not a bad idea.

On a longer TT you could fake a puncture and have the 'guilty' Wheel switched out, or in. Whichever was best to avoid detection.

Whats the cheapest Wheel cover for a 88mm rim?
Is it even Worth it, apart from looking cool.

The wheelsmith one looks good.

I use Aerojackets on an 808. They're cheap.

Just stretch it by hand

Raltec. Don't bother with anything else.

It's Raltech. He said cheapest and Raltech w/ 11spd PT is thus far proving to be a massive PITA so my Aerojackets are winning.

Interesting "Hydration & Aerodynamics" article from Cervelo.

Mounting a bottle B(etween)TA(rms) looks like a win, empty or not, but I don't see anyone doing this: is it because people tend to have the extensions so narrow, that the arms are effectively one unit now, doing the same thing as the bottle?

Thinking about what they say on B(ehind)TA(rse) bottles taming the airflow off the back, is this what Specialized were thinking with the Sitero? The (fixed) position certainly isn't the easiest from which to pluck a bottle.

Similarly, the Selle Italia Iron has a fairing, but I'd think the blunt tail wasn't particularly good in this regard.

Give it a good stretch and you can get your fist in there.

Lets say I have £150 to throw at biek stuff: Raltech cover, or skinsuit?

Current rear wheel is only 30mm and I currently race in a tight fitting Howies Slipstream S/S jersey, which ends up riding up and bunching on my back...

skinsuit

You create more drag than the whole bike.
