I was walking my road bike down a hallway and the freewheel click, click, click stopped and my cranks started turning a few rotations. Then it went back to click, click, click and then again the cranks started turning. Freewheel? Rear hub? Rear derailleur? Thanks. You guys rule.

Do we have to guess What Bike?

It’s a road bike. Does brand matter? It’s a Cannondale with Red22, and Vision Metron 45s.

Probably nothing. Path of least resistance.

It is only an issue if, with the crank stopped, and the chain goes slack between the cassette and crank. Then the pawls could be getting stuck.

I had a few Trek bikes that came w/ those wheels have multiple freehub issues. I don't think it's the design, but more manufacturing defects. For one customer they ended up replacing the wheels w/ the next level up. As far as I'm concerned those wheels are garbage.

Forward or backward?

Meek

Interesting, I’ve had them for 10,000+ miles and never even had to true them.

cxwrench

You're kidding, right?

Meek

I was waiting for the problem being that I wasn’t riding it.

Meek

Actually they’re amazing when compared to my Firecrests. Lol

cxwrench

That's funny.

This doesn't really indicate anything is wrong. So why care if your cranks start turning?

It could be something as simple as the lubricant in the area of the freehub pawls becoming thickened with age or something as complicated as the mechanism itself wearing out and parts ready to fail. Only way to find out is to give it a thorough overhaul and inspection

Meek

Because it’s never done it before (years), and I’d like to fix anything failing before it’s catastrophic or dangerous.
For example if I’d noticed my chain stretch and picked up a new chain I wouldn’t have had to pick up a new chain, cassette and chainrings.

I've seen bikes turn the cranks if there is no resistance on them. Usually not a big deal, and it might just be a matter of the freehub getting old and/or gunked up. Not fun to have a freehub fail on you, though, so it might not hurt to take it apart and see if it needs a cleaning and some fresh grease... or a new hub... or new wheel.

If you look on VisionTechUSA.com you should find a freehub maintenance guide for those wheels. To completely disassemble the hub it looks like you need a special tool, though. For my money, those look like pretty decent wheels. I had some much less expensive Vision wheels; I found the wheels themselves to be really strong, putting up with horrendous abuse on a commuting bike over thousands of miles without going out of true. The freehub failed, though, and I found the cost and difficulty of getting a replacement made it not worth while fixing them. Very different freehub design to yours, though.

The easiest fix is to buy a new freehub body and replace the old one. That will keep you on the road while you decide how to clean and lube the old one and keep as a backup, especially if you have a lot of miles on the original without any maintenance.

I'm not familiar with Vision products, or installation of freehub bodies, but I've done that with Shimano freehub bodies. I don't mess with overhauls that sideline me if I can easily replace and overhaul later.

As you get older, you too will find there are things you've never done before!

I'm not certain what kind of catastrophe you expect. Usually things just eventually get so bad that they make themselves evident that they need to be replaced. However if you prefer remove and replace things that might still have quite a bit more life in them, that's okay. I use to do the same, taking things apart and keeping them clean and lubed. However I've since found it's easier and less expensive to just wait till it shows for certain.

However if you regularly do competitions, then by all means you need to stay on top of everything maintenance wise no matter how small.
