skewer to solid axle conversion???

I have a set of 26" mtb wheels that i want to use on my OM, thing is the have the typical quick release type axles. is there a kit that can be used to replace those with a solid bmx type axles? also can the rear hub that had the multi gears on it be easily converted to single speed?

Re: skewer to solid axle conversion???

There is not a conversion kit for going from a hollow axle to a solid axle. The biggest difference is the way the derailleur mounts to the dropout, and the axle width may be different. First though, WHY? Is this a wheelset issue? I know there are conversion kits to change from a freewheel and cassette to single speed. I think in the end you would be better off converting the wheels to use a conventional axle.

Another thing to consider is the dropouts. On a single speed bike, the dropouts are similar to a BMX to allow for chain tensioners. You can accomplish this with a derailleur style chain tensioner on a multi-gear style dropout but I fear it will not line up with the sprocket if you use a solid axle.

I think this warrants more research....

Re: skewer to solid axle conversion???

I read your post again, I see what you are trying to do. I am almost positive the MB wheel hub is way too wide for a BMX frame. You are better off relacing the wheels with correct hubs.

Standard MTB wheels have 135mm spacing.

Re: skewer to solid axle conversion???

take it to the lbs and tell them what you just said here. i dont have lbs experience, but an axle conversion seems straight forward. if your spacing is
longer then maybe add spacers. again im no lbs. and like to here what the solution was.

LBS won't be able to do anything for him, MTB wheels are too wide for BMX that's all there is too it.

Re: skewer to solid axle conversion???

Mountain bike wheels can easily be converted to bmx. Just replace the axles with bmx axles and remove the spacer for the gear cluster. The freewheel just unscrews like any other freewheel.
The rear wheel will need to be redished to properly fit in your frame. That is the spokes on the drive side need to be loosened and the non drive spokes need to be tightened to make the wheel centered.

Re: skewer to solid axle conversion???

Hey, thanks for the info guys.

basically i have this wheel set that has never been used. Since i need wheels to complete my OM Flyer i figured i would try to make them work. I have been contemplating to have them relaced, but at the cost of new hubs, spokes and nipples along with labour to have this all done, i probably would be over the cost of just buying a complete set.

I just cant seem to find a 26" set of wheels for this thing though

Re: skewer to solid axle conversion???

As Scraplord says, it's an axle swap - the 110-135 gap is covered by a 25mm spacer on stuff I've seen, and a redish is needed. Simple, right?

Hang on...is the skewer axle a 3/8th's axle, or a 10mm axle? That's where you're going to find you have the first headache. If you have the 10mm axle, the cones and locknuts won't work right on the new 3/8ths axle, so, you may need to find new cones, too. First headache? There are more?

Yep. That then puts you into the issue of cone diameter. The outer cone diameter should match closely the inner diameter of the dustcap. This is actually where things break down most. It's easy to find axles, AND, it's pretty easy to find cones and lock nuts. BUT, to find the cone that matches the diameter of your dust cap is where you need a bit of luck.

So, it's simple on paper, way tougher to execute if you're not prepared....

If you find the correct hubs and spokes, I will lace them for you - yes free. Just let me know.

Bullshit!

Early BMX bikes used road hubs. Early Mountain Bikes used either road hubs or BMX hubs. I know this because I WAS BUILDING WHEELS BACK THEN.

Assuming it's a FREEWHEEL hub set, all he needs to do is remove the freewheel and leave out ONE spacer (the thick one) when re-assembling.

The biggest problem is axle size. He can buy 10mm solid axles on eBay...or, he can gut a similar solid-axle hub to get 9.5mm cones and nuts. The second way is the "right" way.

Mountain hubs were 125mm to 135mm, just like touring hubs, but Mountain was always one step ahead (5mm) on size. I already mentioned the spacers, but he'll also need to re-center the rim. Which is easy. Just loosen up all the spokes on the drive side one turn, tighten all the spokes on the non-drive side by one turn, and recheck.  If you don't have a dish tool, slide the wheel in to the end of the slot one way, measure it, flip it, and repeat.

Re: skewer to solid axle conversion???

Thanks again for all the info guys!

although i would like to think that i know what most of you are talking about,
i really don't and it makes my head feel all "swimming" like lol

what i may end up doing is get a set of hubs and have it re-laced.
At least i will have it exactly as i want it to look and feel!

Yes, and as mtbwrxwagon mentioned, your spacing will be at 135mm due to the cassete body on the hub.

Most MTB wheels were historically 130mm, 135mm came out in the mid 90's. Cassettes on mid-level bikes were mostly a 90's thing. So if he has very old MTB wheels, or fairly new mid-level MTB wheels, he probably has a freewheel. And freewheel hubs convert very very very very very easily.
