My bike has shimano 105 (10 speed) cassette on it. I'm looking to pick up a cheap rear wheel for indoor training but the ones that are much cheaper are only 7-8 speed.

Will they still work with my bike?

Thanks.

I think you would have issues but, if you're trying to save money, why buy a second wheel at all?  Use a cheap or used tire for the trainer and swap it when you go outdoors.  It should take up less than 5 minutes of your time and is good practice, anyway.  Works for me.

+1 Trainer tire or old tire = much cheaper.

I've considered doing what you guys say and just changing the tires but to be honest, changing a tire for me is such a bloody hassle and I'd prefer not to.

I just want to know if a 7 or 8 speed cassette will work on a 9 or 10 speed bike for indoor training???

Changing a tire is a lot easier (IMHO) than changing a cassette. Unless you plan on buying another casette to put on the cheap training wheel, in which case it's no longer cheap.

Plus, if changing a tire is "such a bloody hassle" you probably need the practice.

Cool

I'm not going to change the cassette every single time I ride, I'm going to have 2 real wheels with seperate cassette's.

I just want to know if you can do it or not???? Because I can buy a rear wheel with 7-8 speed cassette on it for $30.

Just please answer the question whether or not it is possible to put a 7-8 speed cassette on a 9-10 speed bike?

Thanks......

If you put a 7 speed cassette on your bike you CAN get it to work, but you will need to adjust the derailleur, more of a hassel than changing tire.  Hold out for a 10 speed cassette.

Just did this exact thing - my buddy at the bike shop said to use the same geared cassette on the trainer wheel (i.e buy another cassette with same ratios). He said if you use a different gear cassette you risk stretching your chain and damaging the derailleur going back and forth.  Not looking to start a war on changing tire vs. seperate trianer tire... just sharing my experience.

Kailua, Hi
Subject: RE: Different Cassette Speeds For Indoor Trainer?
Well it could be done but like said before alot of adjusting the deraillure and you would damage your chain, a 10spd chain is alot thinner that a 7 or 8spd chain.  I have 3 sets of wheels that I run on my bikes never a problem with wear or anything like like that.  If you get a wheel that takes shimano or sram you should be able to fit any size cassett on it, its all about the freewheel size.  I dont know if you are aware of this but they make tires to use on a trainer or to ride on streets.  Hope this helps.
