    Pivit hubs, solid axle available?

    I am the happy owner of a Haro Mary SS, and am in the process of beefing it up for all-around trail riding. Going with a suspension fork and some more powerful brakes.

    My only major issue is the attachment of the wheels. The stock skewers bruise my hands trying to take them off, but any looser and the wheels will come out of the dropouts. This is especially bad on the rear wheel.

    I am considering a set of new skewers (Crank Bros., Shimano, etc.) but am interested in converting the axles to a solid, bolt-on setup. Weight and convenience aren't the main concerns for me, I'd rather have a stiff, reliable setup. Is there anything available that will fit these hubs?

    I know the Sun Ringle can be set up with a through axle but not sure about yours. What hub is on your Mary??

    Edit once again do to beerzheimers; The Pivit hubs look like WTB which is made by American and is not convertible to 12mm. Their are some QR type through axles available but I dont recall who makes them. I'll be back when I find them.

    Its been posted here in the Haro forum that the Pivit hubs are Joytech.

    Nashbar has a very similar SS hub which is bolt on, so there may be a chance of actually converting it, but you're just better off getting some good skewers like Shimano XTs.

    Just for reference, here's the link to the Nashbar hub.

    Thanks for the responses guys. I went ahead and took apart the front hub, as it had a lot of drag, and the axle looked really straight-forward. Unfortunately, the hub itself is creating a lot of bad vibes (literally), throughout the bike when rotating, and still has a lot of drag, even after fresh repack of grease and proper adjustment. Look like there might be too few ball bearings.

    Regardless, I think I might want to replace the front hub, and get the DT Swiss RWS system front and rear for more/easier clamping force. Front hubs are cheap and there is little/no dish, so I should be able to lace it all up no problem. Does this sound like a good idea? The RWS seems to be a damn fine system to me, but I can't find much feedback on it...

    Let me back pedal on this, if you need to tighten the skewers enough to hurt your hand to keep the wheels on their is a problem. I had a similar problem, my rear wheel would come loose about every 3 rides and of course when rippin DH. Lucky for me it never came out but definitely left a racing stripe in my shorts. One day when the wheel was off I noticed a washer on the rear axle. As soon as I removed it never had the problem again.

    The bolt on skewers will allow your to over tighten if not careful. If you mean the hallow hub axle snapping I have not heard that. The hub axle shouldnt be getting any excess pressure from the skewer since the axle rest in the drop out not protruding out of the drop out.

    I misspoke. What I have heard, and I imagine this is possible, is that the spindle or rod or whatever to the bolt-on skewer might snap. This makes sense since its essentially a really long bolt, and the torque might bind it or twist it enough to snap. Not the actually axle in the hub itself.

    The wheel has not been slipping out at all lately, presumably because I've been using kung fu grip to close and open the lever. I like to try and pin it as much as possible, so I really just want the stiffest setup possible. The DT Swiss RWS system seems to be the easiest way to get a little extra clamping force and stiffness.

    I would still consider the bolt-on skewers if anyone can vouch for an increase in stiffness over regular QRs, but I haven't really seen any feedback on them.

    I have not used the bolt on axle but do have riding buds that do use them with no problem. Yes with a bolt that long if over tightened I could understand it snapping, surprised you havent snapped the QR yet.

    The best way to go stiff in the rear is with a 12mm setup.
