    240s Bolt On and Surly Tuggnut?

    So I just got a Tuggnut, thinking my rear wheel would be invincible with it and a bolt on hub. Now I realize the bolts wont fit through the holes on the Tuggnut. Amiright?

    240s has oversized bolts - they're like Chris King funbolts. You dont need a tugnut at all with those massive bolts.

    If you insist on having a Tuggnut with OS bolts, enlarging the holes is a rather quick and easy process.

    But they fit in normal dropouts? Not sure I understand how that is possible. Thanks for any insight.

    Go take out the skewer on your bike (without removing the rear wheel) and observe.

    Bugshield, I don't think Phsycle understands what is at question either. Search for "Chris King Funbolts" and find links like this: Chris King Fun Bolt | Flickr - Photo Sharing!

    The SS specific bolt on hubs use oversized bolts, -not- oversized axles, thus fit into standard track ends/dropouts. The point is to the original question: a chain tensioner isn't necessary when using hubs with large diameter bolts (knurled, too!).

    Side note: The majority of SS bolt on hubs like CK, Phil Wood, Paul, White Industries, all using large washers for max surface space. When discussing Single Speed, a QR skewer is recommended only when used in a vertical dropout in combination with an eccentric bottom bracket or a Paragon Slider type.

    I would expect an "oversized" hub bolt (replacing a standard axle) to be bigger than the axle, not bigger than the skewer. Also, it's an adapter that reduces a Tuggnut to skewer size.

    PS. Typed while illnacord was correctly answering my question.

    A picture worth a thousand words.

    I looked in the King Tech Service Manual and should have looked for a picture.

    It all makes sense now. Thanks!

    Anyone in the market for a shiny new Tuggnut?

    Even if you drill out the tugnut, you're probably going to have clearance issue with the non threaded part of the bolt. It's pretty tight without the extra couple mm's of a tugnut.
