Hubdock: a better way to change a rear wheel?

Clever design allows you to remove the wheel and keep the drivetrain in place

Here's a clever thing. It's already been on the forum after Gkam84 spotted it on Kickstarter but we thought we'd give it some news time too, because it looks like a really neat idea.

Even with plenty of practice, changing a rear wheel isn't the easiest of tasks. Remember to shift down to the little cog, undo the QR, pop the wheel out and wrestle it out of the chain. You're left with the wheel (including the mucky cassette) and your trasmission all dangling everywhere while you fix your flat.

Enter the Hubdock. Essentially it's a two-part hub: the cassette and freehub stay put and you can remove the rest of the hub my undoing the quick release on the non-drive side. Look at this video if you're unclear:

Okay, the bloke in the video removes the standard rear wheel like a complete numpty. But even so, there's lots to like about this design. Obviously the big draw is that the transmission stays in place. There's no messing with the chain and getting oil all over your hands and no danger of things getting knocked out of alingment. It keeps tension in the chain too, so there's much less chance of the chain coming off the chainring when you're changing the wheel. Also, if you break a drive-side spoke you can simply take the wheel off and replace it, you don't have to take the cassette off as all the spokes are accessible.

Any downsides? Well, not any that we can think of, other than it's going to be a bit more expensive than a standard hub. Your first production run hub will cost you $379 on the Kickstarter pitch. Okay that's not cheap, but they're basically hand built. That's less than a Chris King hub would set you back. And there's nothing about the technology that necessarily makes it expensive. It's a simple concept.

Do we need it? Well, it makes life easier. It's all very well saying you've never had trouble changing a rear, but there's no doubt this system would make it a much simpler process. You probably never had any trouble with downtube shifters, but you've got STIs/Ergopower/DubleTap now, right? Just saying.

We're fairly confident that this is going to catch on. Especially since we asked someone very much in the industry loop about it, and got a winkey smiley in return...

Only one slight concern - If you fit "normal" rear wheel and fail to tighten quick release wheel will generally stay in place when weight applied to bike. However I'm not sure same applies here..........Do the two parts collapse and the wheel jam in the stays/brakes.

Maybe I'm reading too much into it but it does need to be mistake proof..........After all, punctures only happen when it's raining, dark and at the end of a tiring day.

I carry plastic gloves for such events......fraction of the cost.

I wonder why it didn't take off first time round? Maybe a little different but same principle.[/quote
Hi, Antonio This is the first time we have launched the HubDock Quick Release Rear Wheel Axle and our first Kickstarter Launch. According to the US Patent Office there is no other patent either domestic or international that addresses the specific advantages that the HubDock represent/covers. I have 4 U.S. utility patents on the Hubdock. We are challenged by the volume of comments and blogs needing to be addressed and we appreciate everyones interest. If you can help the Hubdock get out to the bike world we would be grateful. We are offering the Mountain Bike Hubdock on Kickstarter, incase you missed our updates.

They tried this back in the 60's this was done, known as Cinelli Bivalent hubs, but they never caught on. The front and rear wheels were even interchangeable.
