    Thru axels?

    What is the real purpose for thru axels and is there a specific type of hub dedicated to that? How do you pull off the front tire. I have been out of the loop for a while and I am trying to reeducate myself.

    The through-axle fork simply clamps an axle from both sides -- much like a threadless stem clamps a steerer tube -- and the hub is "captured" between the fork legs. An end bolt (similar in function to a headset top cap) or a QR pretensions teh legs against the hub before the bolts are torqued down.

    To pull off the front wheel, most forks require you to use an allen wrench to loosen the clamps.

    Yeah, it's a special hub with a big 20mm hole through the center of it. You'll see them listed as "20mm hubs".

    thru axle = tougher? i.e. more likely to stay in place/not break from big drops compared to a QR axle. yes, different hub required (at least mine looks different) - replacing tyre will require hex key and some patience to remove the axle, putting it back has been the problem for me. It hasn't happened to me yet, but replacing the tube on the trail is going to be a pain in the gluteus maximus.
    That's a lie.

    You can have skinny thru axles. I don't think the design is better, but the fact that most are 20mm makes a big diff. Really a thru axle is a lot like a big ass qr (bolt on, qr regardless, the theory is the same) The only one different is the solid axle.

    I carry tonnes of tools anyways. The difference between a qr, ta or solid is almost nothing. I have the tools anyways

    Thats my take anyways.
