Subject: cheap trainer wheel

I want to build a cheap trainer wheel.

Just bought some new pro race 3s, and I dont want to use them on my trainer.

Not into switching out my tires out every time I want to go on my trainer....much easier just to swap out the whole wheel.

so, I would like to build one wheel, cheaply, that can be used for me and my wife, if possible.  Our bikes are:

wife-2007 Kona Lisa Rd-has a 105 10 Speed Drivetrain with 700 x 23 wheels.

me, 2005 Cervelo Dual has a Shimano Ultegra 6500 nine speed with 700 x 23 wheels.

I suppose the cassette on our current bike doesnt really matter?....I could put any cassette on, no?

My thought was to buy a used wheel on e-bay.  Am I correct in assuming any 700x23 road bike wheel will work for this?   Can I cause damage to our bikes/bike parts by using cheap cassettes?

I know little about bike parts, so excuse me if I make little sense...

 

thanks!!!

THANK YOU  for asking this question!! Hubby and I have the same dilemma!! Hopefully you'll get some good responses. Our LBS could set us up with a wheel and cassette for $170. Needless to say, I didn't buy it!

If you're getting a whole other wheel, might as well get another cassette too. Almost the same PITA factor swapping cassettes as in swapping tires.

Try and get the rim width as close to your existing wheel. If not, you'll need to loosent he brake cam a little when on the trainer. Not a big deal, but...

700x23 is the tire size. The trainer and your bike frame only care that the tire fits inside the brakes, not much else. I wouldn't go any larger than 25mm width.

No problem using a cheap cassette, just make sure it's close to the same range as your current cassettes. A two-tooth differential on the largest cogs should be OK, but don't try to run, say, a 27 if your current largest cog is a 23, for example.

$170 for a new wheel and cassette is not that bad a price.

yes, sorry.  I want a used cassette, and wheel.  Want one complete wheel for both our bikes.

So when looking for the cassette and wheel, what dimensions do I need to concern myself with?  Just wheel size only?  Any cassette will work with our current set up?  do I need to get shimano to stay  consistant?  If she has a 10 spd and I ahve a 9 spd, will a 10 spd work on both bikes?

 

as you can see, I know nothing.

starting to lose me....do those numbers reference the number of teeth on the cassette?

You should bb able to find something for around 100 full set up minus tire. It will be cheap but it is not going to hurt anything. As long as you keep it true, cheaper wheels tend to go out of true faster but on a trainer it will not matter. if you are going to have a detacated wheel i would get a trainer tire for it too, they can handle the heat made by the trainer better. The only prolbem i see is that a ten speed and a nine speed are not going to work together you will have to swap cassets but you can use the same wheel you just need a spacer for the nine speed.

Yep. Basically, if you try to use a cassette with bigger cogs, you're going to have chain length issues and your rear derailleur isn't going to like it.

I have a 27 on my bike and a 23 on my trainer wheel and it works just fine.

But am I wrong that I do not think if one bike has 9 cogs on the back and the other has 10 that it won't work?  I am pretty sure you have to have the same number of cogs...

If you have shifters you can set to friction mode and are careful not to throw the chain into your spokes, it'll work. Otherwise, not so much.

This is a good question. I thought a 10 speed chain was thinner than an 8 or 9 speed chain. If you put a 10 speed cassette on the trainer wheel it seems that the chain on the 9 speed bike would be wider than the spacing between the cogs. I think you will have to ask your LBS or an online expert. I know my 10 speed chain is significantly thinner than my 8 speed, but I don't know what chain a 9 speed uses. I suppose you could measure the chain thickness and verify yourself.

Sounds like someone needs a set of fancy race wheels!

There's usually Easton Vista OEM type wheels on ebay at any one time that people have replaced with new fancy wheels and discard.  Be patient and you'll find a rear wheel.

You won't be able to share the trainer wheel with your wife as you don't have the same cassette type (9sp vs 10 sp).  Maybe it's a good time to also upgrade the Dual to a 10sp!

Don't forget to checkout Nashbar.com and Performancebike.com for deals.  The Nashbar rear wheel and 9sp cassette are on sale right now for $70 and $16.50 each.  I can't vouch for the quality though.

In responce to the chain question a 10spd chain will not work on a 9spd system or an eight so you would need a different chain if you wanted to go that way. the best bet not to mess up the entie system is to stick to either one or the other and not mix. A 23 vs a 27 will not matter much as the difference is not that big.

 I purchased this exact combo earlier today for the trainer.   I'm really hoping the quality is high enough to at least handle the rigours of my living room.

I was in the same situation late last year and was looking on eBay for a cheap rear wheel, but really didn't want to spend the $$$. I told a bike racer friend of mine that I was looking and a few days later he called to tell me he had a wheel, cassette, and tire for me and all I had to buy was a tube. I picked up a 700x25 tube at Wal-mart (I didn't even know they sold that size) for less than $5 and I was ready to roll. I've gotten good at swapping out the rear wheel and I love not eating up my good road tires.

These are only about $25 at REI--should work just fine.
