Just to chip in on the D-Key, it was designed as a BMX product and it does make a lot more sense in this context. I'm still not totally sold on it but having an allen key in a handy size in your pocket along with your keys could be handy and the design allows you to apply more force than is possible with a multi-tool which is necesary for wheel removal etc.

If I'm honest I'm more taken with the socket seatposts and seats with built in storage that have started to appear in the BMX world.

The Clug looks nice and is unobtrusive, I can see that doing well. I'm not convinced that it would be all that easy to use though.

I like the D-Key. It's not revolutionary but as a convenient way to carry a 4mm key at all times it works and it's a bit different. It's a bit of an Etsy product though.

The fairing, yeah... I'm out.

Clug are also providing the 3d data file so you print it yourself if you a access to a 3d printer.

Forget about the Clug, I want a cushion with "merde" written on it.

I am one of the 1800 or so backers for the CLUG. It is innovatie, unobtrusive and incredibly simple. I paid $37 and will get 4 CLUG's in September as the initial funding has now reached the $32,000 target.
I'm here in the UK and am looking forward to being one of the first to own these. I have 3 road bikes and my wife has hybrid road bike. Never will our garage look much tidier until September this year. No more ceiling hooks for us. Simple, stylish, effective. I was sold on this immediately. Hey I'm Scottish and don't part with cash unless I believe in something that is going to give value for money and the CLUG does just that.

Please tell me Nullwinds is a spoof. Not even the Yanks can be that stupid....Oh! They really can be! Sorry, my mistake.

The Allen Key thingy (I can't be bothered to scroll up to check its real name) is a solution to a problem that doesn't exist.

The Clug? Now that is interesting. Particularly like the fact that it can be 3D printed. Small, neat and unobtrusive. A very competitive market but I think this will go well. Certainly until the copies start flooding the market.

The principle of covering only the upper part of the wheel is sound since the upper most point of the wheel is in effect travelling at twice the velocity of the bike whilst the tyre contact patch is effectively at zero.

The execution could use some work though.

Agreed about the nullwinds being ugly, they also seem like an odd design only covering the upper part of the wheel, if it was more of a complete wheel cover with perhaps some kind of venting design to reduce side wind effects it would work a little more. as it would always be facing the same way into the wind the vents could be angled in a more extreme way than on something that has to rotate, and would maybe relieve pressure from the inside of it too.

Clug - Great idea and sensibly priced

Allen Key - Solution to a problem that doesn't matter to most

Fairings - You are having a laugh....right??

The guys with the hex key must not have seen the micro multi tools that....as it happens, fit nicely on a key ring all for about £10

I'm pretty sure those "aero-fairings" used to be called skirt or dress guards.

Nullwinds No thank you I'm out

Those nullwinds are a bit odd - presumably they have no side-winds over there. Obviously, I have never ridden with them, but the fork seems to have most of the faring in front of the fork. I fancy that a good gust from the side would create a lot of turning force.

The guys behind the fairing are about to learn a lesson the car industry has dealt with for a long time. There are all kinds of things you can do to make something more efficient, if only the customer didn't want the things they own to be pretty.
