Hub on turbo

Have been using my good rear wheel on the turbo as I'm still looking for a cheap rear wheel to use on it longer term. Will the turbo ruin my good rear hub ?

    Not as far as I am aware. The only reason I have a "turbo" wheel is to use a turbo specific tyre as it will wear out your decent rubber pretty quick.
    The hubs getting a pretty easy ride on the turbo, not potholes, rain, salt, grit and it's carrying less weight.

    It's more likely to damage your frame than your hub. (And it's not likely to damage your frame unless you spend a lot of time out of the saddle doing power sprints on it).

    Cheers, have a turbo specific tyre. Just wondered if the hub was getting overworked on the turbo but it seems not. Think i'll still get a cheap wheel for turbo work and keep my good wheels for the good weather outdoor.

    Have a look at CRC website for cheap wheel suitable for turbo use, they were clearing out some not long back at much cheapness :)

    As others have said, most people have a cheap turbo wheel fitted with a turbo specific tyre (which are usually bright yellow) because they don't wanna wear out their good tyre, nothing to do with the hub :)

    Yes, it will ruin your hub!

    I used a veloce 10sp rear hub on a turbo about 3 times a week for probably 3 months one winter. The hub made a horrible sound at the end of it. In the end, I put in a cheap Mirage hub to replace it.

    Err..... the turbo didn't wreck your hub. Your hub was just cr@p to begin with.

    How exactly is a turbo supposed to wreck a hub?

    Exactly. Short of sitting in a wheelbag, it couldn't get an easier life.

    i cant even believe you expect your frame to be happy with being basically clamped into a vice and then subject to standing sprint efforts without breaking something, not if you're giving it full beans. i wouldnt even consider it unless i was on a bike i really didnt mind breaking.

    anyway blah blah, your hubs should be fine, but lots of trainers come with a steel qr skewer for obvious reasons.

    Absolutely incorrect.
    The forces going through the hub are far greater than on the road due to the fact that the hub is clamped ,often very tightly to the trainer, meaning that the forces cannot be dissipated by frame flex and side to side bike movement as would bet he case if the bike was being ridden normally.

    It's nearly impossible to do standing sprint efforts on a turbo due to wheel slippage.

    If you feel turbos are unsafe or cause frame breakage under normal conditions, can you please provide evidence of such? I'd be very interested to see this as I have always used carbon bikes in my turbos and have not broken one yet.

    Rubbish. The only forces going through the hub are those from the chain driving the wheel round unlike when riding when there are lateral and impact forces. There are compression forces on the axle due to clamping but they are not great. All the lateral forces due to rider effort and movement are carried by the rear triangle of the frame. These are not dissipated into the wheel as flex so may indeed be greater than when riding. I don't think they are enough to damage frames, at least non that I have heard of and it has been discused often on here and other forums.
    If you wrecked a hub then it was already on it's way out before you used it on the turbo.
