    It seems it depends on the manufacturer as well. I bought an Orbea Orca and the manual explicitly says (multiple times) to never leave any spacers on top.

      Huh, I’ll look into that! Maybe something to do with an integrated stem? Usually those won’t function if there is an extra spacer

      Has to be manufacturer specific; the manual for my 2024 Specialized Crux "requires" one spacer on top.

    Nice to see someone taking pride in their work. Becoming rare these days 👍

    Great idea taping the fork before cutting.

      Thanks, ya super simple step that helps keep the fibres from pulling 👍

    Seems like the tube might have already been compromised by the stem being clamped onto an unsupported section.

      That can happen, but in this case, the stem was only very lightly clamped in position (part of my full bike build)

    I’m torn on this, does the expander plug truly potentially do damage to the steerer tube when not supported by the clamp of the stem? Also vice-versa, does the clamping force of the stem really need any support from the expansion plug?
    My gripe is that I purchased a bike from my LBC when I was in my teens, they positioned the stem at the lowest position for my fit and cut the steerer tube all the way down just like in your video here. Now i’m stuck with a bike that I feel is ruined. The front end is slammed and it’s now uncomfortably low and seems much harder to put up for potential re-sale. There is no option to go back with this and I feel like this advice, or maybe the arguable need for this procedure, is a flaw in the bike industry….

      Thanks for adding, so yes, before it’s cut, you need to know the height for you (who I showcased my fitting in video). Otherwise it can’t go up! It can limit resale as well if no adjustability (this one does have adjustability due to adjustable lower headset spacer). Some designs due overcome this, but they’re less common. And as for clamping, you definitely want to make sure the stem/expander plug line up. Clamping unsupported carbon is a big no no!

      Just get an expander plug that doesnt sit flush but drops downs into the steerer tube if afraid of clamping force from the stem. The carbon fork manufacturer (Seido components) actually told me the steerer is strong enough and the expander just needed for setup. Canyon for ex. with their 1 1/4 inch steerer doesnt have an expander plug. Just a little wedge that enables setting up the front end. Yes 1 1/4 inch steerer is stronger than a 1 1/8 inch. But when in doubt if a supporting expander plug is needed just ask the manufacturer, they will give you the true answer. I ride an uncut steerer because I am too lazy to cut it, and I have the official "go" of the manufacturer...

      Thanks! This cut is pretty important to get right on the first try, so I always take my time and work as accurate as possible 👍

    Do you cut it totally flat or a bit incline (because when try the stem and handlebar on they are a bit incline)

    • @onelastlap9302
      @onelastlap9302  4 หลายเดือนก่อน

      Good question, you just cut it totally flat, no angled cut 👍.
