Hey Guys,

My wheels are just too messed and I need to replace them. The bike has a 7 Speed Cassette and I found these Pro-Lite Como 700 wheels that accept a 9 speed on CL for $80.

I read online that you can get a spacer and be able to run modern higher cassette wheels on older bikes. Would this work?

Thanks! Sorry for posting in the wrong area.

What is the OLD (rear axle spacing) on your bike? if it's 126mm, then fitting a 130mm (current road non-disc standard) into a Alu frame may not be the best idea.

If the OLD is 130mm, then any current road non-disc rear will work (and with your cassette with the appropriate spacers).

Do some measuring to work out what you can do.

A 130mm rear wheel should fit fine on your 88 Trek 1000 (no such thing as a 88 Trek 10000). I did a trial fit with a 130mm rear wheel on the 88 Trek 1000 that I built/restored for my oldest son.

His 1000 had the original Trek wheels on it, and the rear wheel carried a 6-speed freewheel, not a 7-speed cassette. Is it possible that your rear wheel is not the original one?

When I change rear wheels on a bike with a 6-speed freewheel or 7-speed freewheel, I normally upgrade to a 8-speed freehub/cassette combination. You can get a set of new Shimano 8-speed downtube shifters for about $30-$40, and a 8-speed cassette costs about the same price as a 7-speed cassette.

Using a spacer means that the dork disc/ spoke protector ring will not fit/work on the rear wheel.

Also, the Trek would have come with 36 spoke wheels, where the wheels that you are consider buying only have 20 spokes in the front and 24 spokes in the rear, considerably weaker that the original wheels. If you're heavier than average, or ride occasionally on roads that are not the smoothest, wheels with that few spokes will be a mistake.

I'm pretty sure these are the stock rims are the ones that came with the bike, they are the gray magic ones. I check the trek documentation and it looks like they were 7 speed that year.

I just had the cassette reaplaced at the shop and everything is good minus the wheels. So I'm just trying to figure out a replacement wheel set to throw my cassette on. I found those tims for $80 on craigslist that were barely used.

Vlad2010

So I ended up picking up the Pro-Como 700 Wheelset this morning off craigslist.

My question is now, what is the best way of making this compatible with my current set up without changing out the derailleur and chain. The set up was for the original 7 speed freewheel on Matrix Titan S 700c wheels, those wheels are not ride-able anymore.

Would I be able to run a 9 speed cassette (lowest for this Prolite wheel) on this wheel and would it work with the 7 speed index shifter and just omit 2 gears? I know I eventually want to upgrade a few pieces on this bike so I wanted these wheels but at this time I just want to get the bike rolling.

You has described the rear gears as both a freewheel AND a cassette. They can't be both. Which are they?

If your bike came with a wheel with a freehub and a cassette (you said the shop just replaced the cassette), then the easiest way out for now (to use the new wheels) would be to buy a spacer, and use the new 7-speed cassette with the new rear wheel.

Later, when you are ready to pay for STI shifters, you can buy your choice of a new cassette (8, 9, 10?), new shifters, and (if going to 9-speeds) a new rear derailleur. If going to 7 or 8 speeds the old derailleur will probably still work.

You can also go to 9-speeds now, if you are willing to buy the 9-speed cassette, a chain, and use your existing shifters in friction mode, OR are ready to spring for the STI 9-speed shifters.

Sorry for the confusion!

My old wheel set had a freewheel that I replaced with a new chain, before I was told the wheels would no longer be good.

I'm going to pick up this cassette : https://www.amazon.com/Shimano-Speed...speed+cassette and these spacers https://www.amazon.com/Wheels-Manufa...XG3AVZWB1YJVA4

Would there any other parts that I should get? I would still be able to use my 7 speed chain with this setup right?

If the new freehub is 8,9, and 10S compatible, you will need a 4.5 mm spacer to install before the cassette. A bike shop can do what you need pretty inexpensively, unless you need to lay out moola for tools. The chain you bought should be fine.
