Early days but I'm thinking this is a good contender:

I really want one of those Land Rowers from page 2, though. Until now, I had always assumed that Ashrita Furman made it himself.

SpeshulEd 

Kind of want to try the bodysail. That looks like a disaster and a half.

Like I said, just go to the kickstarter page and you can build a top ten right there.

Cinelli's pre-Look clipless pedals. They were from the early '80s. The cleat slid forward onto the pedal on rails. It was then locked in place by a pin that was raised into the cleat by pulling a button out on the side of the pedal. One released the cleat from the pedal by either reaching down and pushing the button in or by falling down, in which case the ground pushed the release button in for you.

But wait, there's more. The axle was designed with a stress riser inducing angle on it that led to a huge fraction of these pedals failing under load. I have a few friends with lovely scars courtesy of such failures. I still have a set of these pedals and a new pair of the cleats, but my wife forbade any use of them over thirty years ago. I'm not sure why I keep them, maybe because they were the first pedals that allowed my size 51 feet to be comfortable.

Nothing wrong with the combo of the three, as long as you put the disc brake calipers where they belong, in front. Sophomore year engineering.

Perhaps I'm just lucky (or more likely the fear of ejecting a front wheel due to braking forces is overblown) but I have 10s of thousands of miles on a bike with a front disc mounted behind the fork and quick release front wheel and it hasn't ever even begun to loosen itself, let alone actually come loose and I do plenty of hard braking (save for mornings like today where the roads are covered in wet leaves). Are there forks and disc brake combinations out there prone to this issue, perhaps designed by people prone to falling on their heads?

so these are clip on anti-aero bar extensions.

Or put the QR on the correct/right side.

For the caliper being mounted out front, if this had been accepted (it was done on a few forks) back in the early 90's when current discs first started to appear, it would be standard, simple thing is, that it didn't take off back then (same as dual discs), and the chances of it happening now are about zero. (note bikes have followed motorbikes in caliper placement, so it's not really a surprise we have them where they are currently located (if you really want a disc for with an out front mount, a UK manufacture Cotic made them, but look to have now gone the normal mount + thru axle design).

What is happening now is thru axles, when the road standard has been ironed out/battles won, QRs for discs may finally dissapear into history.

What would be the difference in wheel retention if the QR is in the right side?

jimc101

The issues that has come up relates to the recall for QR skewers being able to go into the rotor, if they (the QR lever) are on the RHS, as most riders have them with suspension forks, the issues doesn't exist, nor does it exist if using a modern Shimano QR design (on either side), rather than an older design, will leave you go Google for all the specific, this thread has images of the QR's and issues in question https://www.bikeforums.net/recall-ann...sc-brakes.html

Raise you one:

Got it. I wouldn't ride with my QR open anyway...

But it happens. One year, during out annual club ride to Brooklyn, a guy in the group I was leading lifted up his bike by the stem and turned it around as we were leaving a rest stop. When he did, his front wheel fell off. He had ridden the first 23 miles of ride with his QR open.

RPK79

I once did a 30 mile group ride and then drove my bike home on the rear rack of the car only to find the rear QR was open as I was removing my bike. I'm guessing it happened when I was placing or removing it from the back seat of the car since it would stay in the car during my work day and then ride on the back on the way home from the ride.

SpeshulEd 

Good thing you kids didn't sand off those lawyer tabs.

RPK79

Yep. I kept hearing some rattling when I would hit a bump, but didn't stop to check it out since I was on a group ride and then forgot about it at the finish, but when I set the bike down in the parking lot at home I heard it again and inspected.

Y-frame bikes. The bicycle umbrella mount. Drillium. Solid tires.

Erwin8r

Huh? Those are very cool looking (IMHO) and work reasonably well...

indyfabz

I would like to add Mario Cipollini and triathletes to the list.

While it can happen, I simply don't see how you'd make it further than 5 feet without realizing it. I guess if you never use the front brake (I pretty much only use the front brake) you may be less likely to notice but still it is hard for me to imagine.

FWIW, I have always had the QR on my front disc brake bike on the right side. It's easier to use that way as the caliper doesn't get in the way of grabbing it.
