Rear wheel for trainer

Joeyde

Hi Sorry if I missed this is past threads search.

Im looking for a rear wheel for my turbo as I want to get a training tyre as well, and I need different skewers for the turbo and it would be easier changing up a wheel etc etc

So Im looking out for an old wheel, what Im wondering is if any old wheel will do and if I need to get the same cassette on the wheel. I have a 10-speed on mine. Will it be grand on an old 9-speed/8-speed if I keep it in the one gear and use the magnetic resistance. Im thinking chain length here.

I have a 50/34 compact chainset.

Any rear wheel should do, provided it is the right size for your bike, which should be fairly standard, and has the same hub (Shimano/SRAM compatible, or Campag). There is usually nothing specific to turbos except the skewers, and ideally a turbo tyre, as far as wheels are concerned. As to the question of 8/9/10 speed, while I'm not certain, I would think that you should have the same set up as you have on your good wheel, as while your concern is chain length, there is also the issue of chain width - 10 speed chains are a lot narrower than 8 speed, and may in fact be damaged by too different size a cassette (9 speed might not be as bad, but still not ideal). Worst case scenario, the link plates get forced apart, and eventually the chain breaks, possibly while you're on the road. Additionally, because of the unequal spacing, I could forsee difficulty in getting a 10sp derailleur to line up properly with an 8/9sp cassette, which could lead to accelerated wear in the drivetrain.

Obviously it's up to you whether you want to take the gamble, or maybe someone will come along and prove me wrong, but on the basis of my limited knowledge, the above would all be concerns I'd have in your position.

Cython,

Thanks for the reply, I didn't consider the chain width at all. Much appreciated.

Any shimano compatible wheel and find a 10-speed cassette to stick on will be the easiest I imagine, I want to avoid ware on the bike.

Came off the trainer as the skewers didnt sit in right, bit of plastic came away from it...I got the trainer over the rollers to avoid that :rolleyes:

Joeyde would a 105 11-25 cassette suit?

If you currently have a 10 speed Shimano ( or Sram,I think) it will definitely suit.I use one myself.

If you never need to change gear, an 8 or 9 speed cassette will actually work fine. There is no problem with chain width: it is the outer plates on a 10-speed chain that are narrower, the inner are exactly the same size. So you can use a 10-speed chain no problem on an 8-speed cassette, but not the other way around. I've actually had to borrow an 8 or 9 speed wheel after a crash to get me home (home was 160km away) and I was amazed by how well it worked- even all the gears worked except for some skipping in the very middle one.

Having said that, unless you had the 8/9 speed wheel hanging around, if buying new you might as well go for the 10 speed cassette. You may have chain length issues on the road if you went for a cassette with a larger big sprocket than you have now, but this would not be an issue if you don't need to change gear up into that sprocket on the turbo.

All Shimano and SRAM 10-speed cassettes are compatible so get the cheapest available.

If its attached to a wheel

The wheel is what Im looking for really. Going to try Rothar or somewhere like that this weekend.

Thanks for all the enlightening advice lads.

@Blorg, how did you manage to get someone to lend you a wheel? Were you cycling home from an event or something?

It was a club weekend away and fortuitously the crash happened not too from from our club secretary's sister's house, where he had a spare bike, just it was 8 speed. Happened on the first day but I was honestly surprised it worked so well, no problems cycling home the next day on it either.
