    Not being a mountain biker I never thought about through axles before reading this thread. I have done a little reading about them and they seem to be stronger and stiffer but with some possible weight penalty. Seems like a marginal design gain that requires a large new investment.

    Through axles appeal to me but I am not a big weight weenie and it seems like a good idea to use the best technology to keep the wheels on the bike. It seems like tandems should move toward though axles but my investment in wheels and tandem frames will keep me using my adequate steel skewers for some time to come.

    Now if I wanted the lightest tandem I would use Ti skewers and a cable shifting double chain ring.

    Totally agree with what-I-got-is-what-I-got... for now.

    Before studying up on this topic, I was all for the notion of using Ti skewers on our tandem. Afterward, no way. For starters, Ti is too elastic for very long skewers (145mm+ spacing) especially when using 5-6mm thick QRs. The head mechanic at my LBS (a shop heavily into mtn bike racing setups) demonstrated to me the diff between a long Ti QR vs a steel vs a 12mm Alum TA. Toss in disc brakes and the torque they impose on the dropouts is a major factor to stick with at least steel QRs.

    Ti is a great material but my understanding is that no matter the alloy it is about twice as flexible as steel. In cases when the design is the same diameter rod as the steel version like skewers, square taper BB spindles and pedal axles it will flex about twice as much as the same size steel rod. I guess that applies to stretching a skewer as well.
