Cassette vs. freewheel(11 posts)

Cassette vs. freewheelTroyboy
Feb 5, 2002 1:42 PM
What exactly is the difference? I've got a wheel with an old Mavic hub that I'd like to use on my trainer. The hub takes a freewheel not a cassette. Could I find a 9 speed freewheel to work with my DA 9? Are they still buyable? Any help would be appreciated. Thanks!

Freewheels thread onto the hub, and have the ratcheting mechanism in the freewheel. Cassettes are only gears that slide onto a freehub, and the hub contains the mechanism. They are not interchangeable.

I don't know of any 9 speed freewheel.

Thanks for all the info. I checked with Sheldon Brown and looked for a 9 speed freewheel. They apparently don't exist.

Although there are/have been a few 8 speed freewheels made, freewheels basically ended when the world moved to 8 speed. 9 speed was never made.

Seems to me this would be a good challange for an engineer/machinist. Make an adapter that screwes on a rear wheel, but accepts cassette sprockets.

Since you are going to use this wheel on a trainer, you could just use a 7 speed freewheel and non-indexed shifting.

I plan on using it on the trainer, pre-race, on the road, only. I'm no *wrench* so I simply want to switch wheels for a 45 min. warm up session. I don't want to shred race tires. I don't want to adjust anything or have anything go wrong. Would it work for my application with my DA9 rig? I don't want to adjust the rear der either. How about my Rec10 rig? I planned on taking it one bike at a time starting with my DA, which is my mostly crit bike.

I'd just get a really cheap wheel that has a cassette to match your race bike's, especially if you don't want to have to adjust anything. You can get some wheels really cheap. Here's one for $70: http://www.performancebike.com/shop/Profile.html?SKU=10668 There are others there, too.

Get one that matches. You'll have a spare for the races, too.

Thanks Doug. I didn't think so either. Thanks for the link.

Glad you cleared up what you meant about "trainer". I made a bad assumption that you were taking a road bike and using it on a trainer for the winter. The advice about getting a training wheel from Performance or some other mailorder house is what I did several years ago.
