Need help converting a 6 speed wheel to singlespeed(8 posts)

Need help converting a 6 speed wheel to singlespeedSSC SL
Jan 2, 2004 9:54 PM
I have an old Trek 660 with a 6 speed Dura-Ace hub. I can remove the freewheel, thread a BMX freewheel on and redish the wheel. Is there any other way of converting the rear wheel so the wheel doesn't need to be re-dished?

If you're lucky, you might be able to put some sort of spacers to keep the SS freewheel from threading on all the way, but then you'd be loading the remaining threads even more, possibly resulting in thread failure.

FWIW, a 6-speed wheel isn't really too heavily dished.
yes, there is....gspot

There are actually 2 ways, but ony one will work in this application. the first way, which isn't much help here, is to buy or repacle the rear wheel with one with a cassette hub. That way its easy to add spacers to the cog to get correct chainline. The only caveat there is that the spacings on the newer cassette hub might not match up with the old frewheel spaced hub.
The other way is to add spacers on your chainring where it attaches to the spider to push it farther inboard, which gives you a better chainline. Sheldon Brown sells little spacers like this...
You might need a longer bb for this, and watch out for chainstay and chainring clearance. Or, if your bike has an old adjustable BB on it, swap the axle around so that the shorter side is on the drive side, if you have the chainstay clearance.
good luck, and no gears

I used the methods gspot mentioned as my rear hub is an old Phil Wood freewheel type and there are no spacers to rearrange...by combining all of them I eventually did get the chainline perfect. However, it would be better to redish if possible as the finished bike will look better and the rear wheel should be stronger...also you can get the chainline right the first time w/ the right mix of spacers. FWIW there is a great article on chainline at

Thanks for the advice. I am thinking of just buying a rear wheel with a flip flop hub from Harris Cycle. They have a reasonably priced one that has the correct spacing for my frame. This way I can put a have both a fixed gear and a single speed. They have an option of a solid axle or a hollow axle for quick release. Is there a reason not to go with the quick release?

if you run track fork ends, or horizontals, ithas the poential to slip. also, b ike theives can eaisly steal your rear wheel.
if you dont want your rear wheels to slip, find an old steel QR skewer, your LBS probably has plenty lying around. The steel serrated faces eon't slip when wrenched down hard on your dropouts. Or, if you don't want to change the skewer, get some serrated washers from the hardware store and put those between the faces of the QR and dropout... that should't slip...
They slip. (nm)Dave_Stohler

Took the cogs and spacers off the freewheel, used enough of the spacers that came off to aline the cog I wanted, and used a lock ring to secure it.
