I have an 'Elite Crono Mag ElastoGel Trainer' which I got from Wiggle but I don't want to put my bike on it just yet as I have heard that these trainers chew up normal road tyres pretty quickly.

I am considering getting a spare wheel with a training tyre so that I can swap between the two without too much hassle and savoring my existing tyres. I have heard it is pretty specific in what I need to get, a rear wheel that matches my existing one with the same cassette? but this is where my ignorance comes into play and I was wondering if anyone could give me some advice on what I need to buy/ be looking for, even better if someone had a spare wheel for sale that would be compatible with my bike.

The bike is a Giant Defy 2.5, The full spec for it is on the giant website: http://www.giant-bicycles.com/en-gb/bik ... /fullspec/

Hope it isn't too costly.

    My thoughts are buying the parts is not difficult, the problem will come from the fact that you will start to wear your chain down, whilst using two cassettes.
    If you use both, then there is no real problem, but if you don't use the trainer for a while, (i.e. summer) you could end up with cassettes with different amounts of wear on them, your chain will not cope very well with the newer cassette. (Same goes for winter on the trainer and then changing to road for the summer).

    You could either change the chain each time you swap the wheel, or just replace your chain more frequently to minimise the wear on the cassettes.

    Either way, changing a tyre seems much simpler and more cost effective.

    If you do decide you really want a spare wheel, just buy any rear wheel that has a shimano compatible freehub, no need to buy an expensive one if you are just using it on a turbo trainer. It is worth buying the same cassette though for reasons stated above (unless you go for two chains as well, but stick with a max cog 25 on the rear to save you having to tweek the rear mech height).

    Doesn't sound so bad just getting the tyre, as you said, it wouldn't be very good for the chain and it would be cheaper. Does it roughly take about 10 minutes or so to change the tyre each time? I can't imagine it being too time consuming :wink:

    10 mins is about right, depending on how easy the tyre is to get on and off the rim.

    Make sure you buy a decent track pump, road tyres are very hard to pump up with a normal mini pump.

    Why not get a frame specifically to use on the turbo trainer? Any old cheap frame will do as long as it's the right size. You don't need brakes just some levers - you could use down tube shifters non-indexed. In fact you could use just about anything that will reproduce your normal riding position.

    The big advantage is that you won't be wrecking a decent bike and, because it's always ready to use, you'll be more inclined to use it.

    My turbo trainer has an old bent frame and wheels I'd never use on the road. The rear mech is a really old Campag Record. Just a single chain ring. But it works and is ready for use at all times.
