The craziest part is that the electric bike guy actually trains for this and warms up before the events.

The thing is, it's a hard job because you have to be robotic and get it right the same way every time. It's one of those, "You know they did a great job if you never notice them" types of jobs, like being a pro sports referee or umpire.

Hat-off to derny drivers everywhere :thumb:

I was a human derny for a keirin series one day at the track. I'll never do that again. Totally exhausting :D

UCI scraps 3:1ratio
UCI set to scrap '3:1 rule' limiting aero race bike design - Cycling Weekly

Hahah, way too much pressure for me. I have my hands enough full just holding my line on warm-up laps.

That's big news. I know that a few of the higher-end track bikes (like the FES and Felt TK1) changed some of designs to meet that rule. And several TT bike manufacturers on the road/tri side as well.

This is big news

I'd better start saving up!

I can't wait to see more crazy track frames like old days.


BTW
I found a perfect way to warm up your body before a race

That probably won't happen. I'm pretty sure that the UCI still requires a double triangle "diamond" frame which requires a top tube, a down tube, a seat tube, seat stays, and chain stays.

Some of the bikes from the 90s left off one of the above.

No top tube or seat stay:

I would LOVE to see these designs be revisited using modern carbon materials and techniques.

atl least they can make a tubing that looks like a knife

Smiliar to old Look Time Trial bike

With the E-Bikes that they are using, I don't understand why they couldn't just use a microprocessor to control the speed. Derny driver starts the bike in manual mode, get's it up to speed and pulls a trigger on the backstraight. Then it's all autopilot from there.

I think that would be legal again. But, remember, they are simply undoing a rule that they made around 4 years ago. We didn't have bikes like the LOOK 5 years ago. The Specialized Shiv was the closest, I guess:

Yeah, that's a thought. Maybe the programming cost and risk are a deterrent? Who wants to ride an automatically accelerating motorbike? :D

Well, you still leave steering and brake control in the riders hands. I mean, modern cruise control would be easy enough to copy.

Mavic is making affordable aero wheels(non carbon fiber cosmic)

I really hope they sell the rim separately, so I could try them with track setup.
However, I am not sure if this is going to be a tough rim(or stiff) like velocity deep v.

I think Parlee disc tt frame is the closest 2017 aero frame

Look at those head tube !!!!!

I cannot upload two pictures at once.....
Probably it's because i am using android.:twitchy:

Hotlinking makes for bigger images.

This tech has been around for a while: Aero Disc Covers - Wheelbuilder.com

But, I can't recall seeing it for simply deep wheels that are not discs. But, if you recall, a lot of early deep section wheels were built like this. Cosmic Carbone? or something like that?

There are some others out there. Mavic has made some carbon clinchers with an alu rim like this, and the HED Jet is another popular example.

However, for this model, they're replacing the carbon with a sealed foam. Funky. I bet it won't be too affordable, unfortunately. And, given the fact that there's a specific angle for the spoke to pass from the hub through the fairing and into the rim, rims like that generally aren't re-laceable to other hubs.

But wheel cover is not uci legal.
However the cosmic is uci legal wheel

The Cosmic and Jet are legal because you cannot remove the fairing. They are integral to the wheel, and because the carbon IS structural to a degree, you can say it contributes to the strength of the wheel, which is how those wheels get around that legality. The only difference between the Cosmic/Jet and other carbon rims with aluminum brake tracks is where the spokes are anchored. With a typical carbon/alu rim, the spoke nipples are seated on the inner circumfrence of the carbon fairing. The Cosmic/Jet anchor in the aluminum rim bed. If properly made, you can have this construction and still have a wheel that is stiffer than a regular aluminum box rim, hence why it is legal.

Ok guys I didn't find this on the web but I didn't know quite where else to put it.
Since I've finished my degree and searching for a job isn't keeping me quite as occupied as it should I've been doing home projects to keep my mind ticking over.
I've had a crack at making full carbon fibre shoes. I've only made this one shoe thus far and given to a mistake in the location of the cleat nut set I will no longer work on this particular shoe but it gives a decent representation of what I am aiming for in the end game thing if much rougher and unrefined.

Are those folds/creases excess resin? If so, then they should look pretty good when you're done. Great job!

Nice! Keep us posted on the progress.

Most of them are yeah but there are still quite a few folded fibre layers as a result of a ****e vaccuum seal on the bag I used which I couldn't fix. Next time round I'm going to take extra extra care on that sort of thing to prevent it happening again!
I'm still going to sand these excess resin creases down though and experiment to see how to get the best final finish.

That is the most complicated shoe I've ever seen.
