142mm hub on 135mm rear spacing

[shadowfox]

Hi,

I am trying to build up an NS Surge 2 frame, and I was wondering if frames with 135 mm rear dropouts can accommodate a 142mm hub.

Thanks

Nope.

As the number suggests, 142mm is 7mm wider than the dropouts on your frame. Also the Surge is 135x10mm, so you have to have either normal quick release or 10mm bolt up, 142x12mm simply won't fit.

If it's a wheel you've already got, check with the manufacturer to see if they sell adapters or a different width axle. Otherwise buy a 135mm quick release rear hub.

Thanks for the response fix the spade.

I was planning on building the wheel set, so now I'm looking at going with the 135x12mm hope hubs with the sun ringle 12-10 step down thru bolt. Do you think there's much benefit to the 12 mm bolt over a 135x10mm hub and a 10mm thru bolt? I guess the difference is the 18 dollars for the axle, but I wouldn't mind too much if it was worth it. Thanks again for the advice, it's much appreciated.

cheers

On a hardtail there's no benefit to a 12mm hub and step down axle, you're better off with a 10mm hub and thru-bolt.

On a fs bike 12mm makes sense as the axle screws directly into the frame, it joins the ends of the swing arm more securely. Which is good on a swingarm that's not directly attached to the frame and may not be triangulated at all. On a hardtail it makes no difference as the stays are welded to the frame directly, there's not really any chance for flex in that arrangement.

Also the Surge is a really stiff frame to begin with!

That bit about the full suspension cleared things up a lot. It makes sense that a hard tail doesn't need that, lol.

Thanks Again!

If you can machine 3.5mm off each end of the hub axle, it will fit perfectly. The chainline is the same. A 142mm axle is 3.5mm longer to step into the 142mm dropout which has a 3.5mm deep recess. You can also sleeve the 12mm axle to use a 10mm thru-axle.

It is easier to just start with the right hub, but if you already have the 142 hub, it is possible to use it.
