Sorry for a repost on this but thought I'd see if anyone had stumbled across anything in the past year or so.

Wondering if there are any solutions out there to slip wheels originally 15mm onto 20mm axle bolts (on an XR+). Why I ask is because I have some sweet wheels that need to roll but the buggy axle is set for 20mm bolts.

Bearings with a large ID - needle bearing maybe?

Reducer for the bolt?

Thoughts? I'm close to having buggy #2 rolling here just need this detail sorted out. (Front wheel showing...before y'all start telling me it's 12mm ; )

here ya are mac http://www.awindofchange.com/product/20mmwheeladaptors.html

DOH! I read it wrong ! It was the "reducer for the bolt " that threw me! Yeah, that's it.!

Do you need this for the front and back or just the rear??

For the rear, you can get a short 20mm bolt , drill a hole in the center and tap it to 15mm. This will act as an adapter for your axle. The second option is to get a short 20mm bolt, then weld the 20mm head to the 15mm head. This way one end is 20mm and the other end is 15mm. Screw the 20mm end into the axle and you now have a 15mm bolt to put your wheels on.

For the front, you can use the 12mm bolt with 2 reducer on the holes in the fork to get it down to 12mm. The reducer is usually used on the 20mm wheels to get it to 12mm. You can get the same reducer but use it on the fork instead. This is the reducer that Weldinggod mentioned above. This is assuming your fork is made for 20mm. If it's made for 12mm, then you don't have the issue on the front wheel.

Ding ding! Good call Van! Thanks!

(It's for the rears. The front will ride au-naturel.)

I used the head to head method on my speed buggy ... this way you can angle the heads and get camber!!! If you can drill and tap, that might be more reliable for you in the long run.

I don't think I have a 15mm tap here but I do have a Nut & Bolt store 2 blocks away. I'll grab a few.

If you tap the hole for 9/16" , you can then use a 9/16" bolt instead. It's almost 14.5 mm . You can use shrink tubing on the bolt to get it to 15mm so it will fit the bearing tight. It's a suggestion if you want to try it that way. Good luck!!


edit: Is canada using the metric bolt size or SAE?? I keep forgetting ... haha

Canada is "supposed" to be using Metric measures but we're all over the map. Inch, Mils, English, French.

I unearthed the wheels from the shed the other day and much to my delight I realized the bearing elf had been by - there were 20mm ID bearings sitting in the hubs!? Apparently I bought them last year and forgot. Serves me right for being lazy. Good thing karma didn't make me order a new set.

Still needed the inner hub spacers and since my new bearings are thinner than stock I had to get them custom cut. There is no such thing as metric pipe in Canada but 3/4" fit around the axle bolt well enough - esp since the actual function is to hold the bearings in place outboard in the hub. I'll silence them down with some rubber inserts and hopefully it all rolls nice.

All that's left is the headstock bearings which I should receive from Kent in the very near future and a new custom sewn seat which I'll finish this weekend and I'll have one blinged buggy as a spare!

@ van - Of course once I get your new rail kit and seat I'll then have a spare but that's OK I'm building in a better back support into the new one so likely the stock seat will take up residence on the shelf. When you're ready to fire the rail kit my way shoot me a U2U/email and we'll do the deed.
