    Long(er) skewer?

    Hello all! I tried my luck in other areas of the forum to no avail. If you guys can't help me, I dont' know who can.

    I need a longer skewer to accomodate a spacer so that I will be able to safely use my trailer "hitch" with my bike. The way my bike (Marin Muirwoods 29er) is built, the cup doesn't lay flat against the frame. Long story short I need a skewer with at least 18 cm of usable space. I currently have 17 cm (see pic). Does anyone know where I could purchase a longer skewer or anyone that custom makes them?

    Any help is greatly appreciated. If this problem is solved, it will save me from having to purchase another bike.

    Thanks,
    Jon

    bob trailer sells one for 160mm dropouts.
    in general, a 160mm dropout tandem skewer should do the trick.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    All help I can offer is that the longest skewer I've come across was included with a tacx trainer. Can't tell you in numbers, but it was a chunk longer than my stock MTB skewer. At a pinch you could purchase some threaded rod in the right size and bodge something together. That'd probably lose you the "QR" feature though.

    If the skewer needs to bridge across open space to hold the trailer on, it'll need to be incredibly strong. Are you modifying the fit with washers?

    You could try buying one of those allen-key-pseudo-QRs and replace the skewer bolt with a longer one from a fastener supply shop.

    The OP has a skewer that is 17cm (170mm) and looking for one that is 18cm (180mm) or longer.

    As for the OP's issue, I'm not that familar with the different types of bike/trailer hitches, but IMO getting the hitch away from the QR skewer would be a good thing. I'd try engineering up some alternate method.

    Skewers have to be significantly longer than just the dropout spacing. They have to be long enough to go through the hub, both dropout thicknesses and have enough length for the threaded nut. Typical road bike skewers (130 mm dropouts) are 160-165 mm long and MTB skewers (135 mm dropouts) are 170 mm long.

    A tandem skewer intended for 160 mm dropout width should work as it should be 190 - 195 mm long.

    I'll have to get a picture of the bike to show you why it needs to be longer. I do plan on using washers so the skewer isn't just going through dead air. Most bikes have flat dropouts, but mine are "cut in" to the rear fram tubes. I need a longer skewer to safely go through the hitch cup, the spacer I'll be using (washers or similar), and the dropouts while having enough thread to safely attach the nut.

    QR isn't really necessary. If someone could show me a safe, decent looking solution for allen or nutted assembly, that would be fine. Thanks for all the help! This is awesome!

    The 160mm spacing is specific to Santana built tandems AFAIK.

    Try the larger tandem shops. GTGTandems is one.
