    What kind of axle does your bike currently have?

      @stratdelux09 If you google "thru axle" it comes up both ways.. with a hyphen and without.. so I just did it without. As long as people can find the video and get the help they need!

    Thank you for the post.... i figured I couldn't be that dumb that I couldn't get the wheel back on the bike. I'm still debating on the dumb part but after watching the video, i was able to put the wheel back on in minutes. My problem.... i didn't set the chain to the smallest gear. I really appreciate you saving me $50 and the humiliation of having to take it to a bike shop or ask a neighbor. My wife thinks i'm a man again and i feel better about myself. Liked and Subscribed

    Thanks for the clear explanation on removal/re-install with these thru axles. First time I worked on one of these and your fine point details finally got the job done after struggling for well over an hour just trying to get the wheel off. For the normal recreational rider, my opinion on this is these thru axles are way to complicated for the few times one would have to remove the wheels and then re-install them. But, thanks again for the excellent video and help.

    Hi Mark! Doing an ironman as well soon and just switched from a quick release bike (Trek Emonda SL 5) to a thru axel bike (Canyon Aeroad CF SLX Disc eTap). I tried to put my bike on my Wahoo Kickr (direct trainer), but noticed it needs a different part to fit on it. When I tried to put the back wheel back into place, I was struggling because I was trying to do it the same way as my quick release bike. Then I found your video, and the part where you say you bring the derailleur towards you really helped me. It was an amazing moment because I realized how easy it was when you have the right technique! Thanks again and cheers!

    Hey, thank you for this tutorial, it helps me a lot! One important question remaind though: how much pressure would be applied if there is no torque wrench at hand. I would approach 25 Nm somehow safely. Do you agree with chatgpt about this idea?
    "2. Finger-Tight and Then Partial Turns
    Tighten the thru-axle finger-tight (as tight as you can comfortably turn with just your fingers).
    Then, apply 1/8 to 1/4 of a turn more using a wrench. This usually brings you in the range close to 20-25 Nm for a rear thru-axle. Go very slowly and check the tightness frequently."

    Nicely done video, but doesn't address a problem I encountered. After removing the thru axle, my wheel won't just "drop out", rather there is a considerable amount of friction between the wheel and the dropouts. After a while of fighting with it I got it out by gently bending the chainstay outwards, giving the wheel enough room to come out.

    Great video - fyi you missed a step at the end by not re-engaging the derailleur clutch. Also cringed at some point when you touched the brake rotor with your hand - I have heard that is best not to do... Curious if there are any issues with having a bike with hydraulic brakes upside down to take off the wheels. Thanks

    • @TheMarkList
      @TheMarkList  ปีที่แล้ว

      Jim, you don't need to engage the clutch to ride. I often leave it off on my gravel bike. As you can see, the bike shifts just fine without it. Before they existed, everyone's derailleurs worked just fine without one on the bike or engaged for that matter. Touching a brake rotor does nothing to the rotor or braking performance. You don't want to spray them with chain lube, but touching doesn't do a thing. Also flipping your bike upside down is harmless. Just pump your brakes a few times. I recommend most mtn bikers leave their bikes upside down to get oil on the important parts of your fork stanchions and seals which are usually neglected due to gravity.

    @gnatman1102 ปีที่แล้ว

    There's one problem with my Specialized Diverge. With the axle removed from the rear, the dropouts spread out a few mm, making it difficult to reinstall the rear wheel back properly in the dropouts. They easily miss the stops of the dropouts and end up rubbing against the stays on both sides to the point of scratching the paint badly. Fortunately, the frame is aluminum. When not using the repair stand, it is always a precarious process to make sure the wheel is in the dropouts before removing the hand holding the bike to insert the thru axle. I've watched so many videos, and I've noticed everyone has no problem with this. I'm wondering if build tolerances are too large, and I have one right on the edge of too wide. Any thoughts on this and ideas to ease this process would be appreciated.

    • @TheMarkList
      @TheMarkList  ปีที่แล้ว +1

      So there's a possibility that you have the wrong width hub on your rear wheel. If you flip the bike upside down, it's wayy easier to manipulate and drop the wheel in.. You don't need as many hands and you can see more.

  • @auomauom

    My rear thru axle doesn't thread when the wheel is on. But it threads fine without the wheel. What's the reason for this? The hub looks perfectly aligned. Should I push the rod in more to hear a pop like you did?

    • @TheMarkList

I did exactly what our host here did, but when the wheel came down the chain wanted to stick in the cog and shit got weird. Aaaanyway, glad to see I wasn't being a complete idiot, but seriously confused as to why it was such a bear. (I'm guessing I didn't pull the deraileur back far enough)

      Sounds like your chain was either kinked or had a stiff link. If your chain doesn't behave you may have to guide it with your hand as things don't always go to plan or behave like it did in the video!

      Also, go slow and don't force anything.. I know it can be quite frustrating at times!

      @@TheMarkList Thanks for the reply -- I took the wheel off again yesterday and it was a bear getting the chain off that lowest cog again. It went better this time but not smooth. Next time I think I'll try the next to smallest cog to see if that takes some lateral pressure off the chain.
