      Jobs you *really* should do every 6 months or so, say, eg remove and re-grease pedals, remove and treat seatpost to stop it seizing, etc. What are the simple jobs which have the potential to save you a major expense, potentially up to a new bike if, say, the seatpost is totally seized.
      I remove and re-grease pedals periodically about 6 months and this has turned a job which used to be very stressful into one which could not be more straightforward.

    • @mmmbetter55
      @mmmbetter55 2 роки тому +2

      Hold the front wheel between your legs, and use the front plate bolts of the stem to align the wheel precisely between them. I usually tighten down the steer-clamp bolts (on the stem) to just above finger right, so you can adjust the angle but it won't be easily knocked out of place while you finalize the position. Most bars will also have hash marks around the stem clamping area to assist in leveling them and evening them out left/right.

      Hold the wheel at a 45 degrees (to the right or left) and line up the opening of the clamp (the crack) with the center of the tire, looking through one eye at at an angle from behind. The trailing section of the tire lines up with the crack, while the leading section (in front of the fork) will be centred between the two top bolts of the handlebar clamp. Using both these references of the stem, you should be able to line up the stem straight.

    It's funny, back when I had an 80's Panasonic bike, I brought it into the shop because of derailleur issues. They told me that my headset bearings were completely shot, and the ball bearings had worn into the metal. They were quite insistent that it needed to be replaced, but I never did it. I actually liked how it felt, the handlebars gently popped into place when centered, it honestly felt so natural it was like it was designed that way. Plus, it didn't affect the performance or efficiency of the bike (unlike that derailleur issue, which they were never able to fix.)

I might add information on the various common headset standards and dimensions, bike manufacturers' recommendations on spacer height above and below the stem, and the sometimes quite time-consuming task of getting your stem aligned with your wheel, but that is more related to the stem rather than the headset (and you probably have videos on that already).

      It's just some gauging, alloy steerer tubes are more resilient, you don't have to worry about them getting crushed by a stem. The pinch bolts would snap or the threads on the stem body would strip first.
      But yes, they're designed not to be removable, which is indeed a pain unless your fork has a hole at the bottom for the old star nut to be punched through.

  • @zygmuntthecacaokakistocrat6589
    @zygmuntthecacaokakistocrat6589 2 роки тому +8

    You missed entirely that the No. 1 cause for loose headsets is that the loose expander plug is pulled up the steerer by overtightening and bottoming-out of the tension cap & its screw, and how to reset and tighten that down - often involving disassembly of the expander plug and clean/grease of its parts. You can't get preload if you can't tighten the tension cap screw into it. Also, a lack of clamping gap between the top of the steerer tube and the top of the top spacer (which you should pretty much always have on top of your stem, under the tension cap). So many of your maintenance videos are like this: do half a job and missing important points, which might one day come back to bite you.

      The goal should be to recess the top of the steerer about 3mm below the top of the stack (stem plus any spacers). It is also not a bad idea to always have at least a 3 mm spacer on top for carbon steerers so there is plenty of “meat” left of the steerer to clamp onto.

      @AnotherMrLizard 6 місяців тому

      Most likely you haven’t got a gap from the top of the stem to the top of the steerer. When you take the stem off (or spacers if you have any above the stem) you should have least 3-5mm gap between the top of the stem and the top of the fork steerer that’s in the centre. If you haven’t got this gap or it’s not enough then the fork bottoms out on the topcap before it preloads the bearings. If that’s the case an extra stem spacer will do the job.

      I'm now riding a bike with a carbon steerer tube and an aluminium stem. The last time I lost some preload is because I barely had enough preload due to the lack of a 0.3 mm shim, so with enough bumps on a ride, it'll go loose. Now I have it installed, I'll need to see how it goes, which I don't think will happen again.

    Bought a road bike built by someone who managed to be almost as bad of a mechanic as I am. He had a lot of spacers, but ultimately the steerer tube was a tiny smidge too long for the number of spacers, so the top-cap hit the steerer before the bearing got a proper pre-load. Replacing one small spacer with one that was another 1mm thicker solved the slight movement. I will chop off the chimney soon, once the fit is finalized.

    I’ve bought a used bike with a super slammed steerer. My only option to rise it to add only about 20mm of spacer, been thinking of adding more but it will result having the steerer to be halfway in the stem. Is that ok or not advisable to do?

    Threaded vs. unthreaded head set? Are threaded head sets an old design and not used anymore? I've a 9 year old Cannondale Synapse. No matter how tight I screw the top cap the load on the bearing doesn't increase for some reason. The steering does not get "sticky" and it still makes creaking sounds when I ride out of the saddle or ride over sharp bumps. Sounds like it is falling apart. I hate it.

    • @keithreed5009
      @keithreed5009 2 роки тому

      It sounds as if the top cap is hitting the steerer tube, try adding a thin spacer or shorten the steerer tube by 1.0mm

      If its an aluminium steerer tube Check that the middle part the star-nut is not stripped or spinning, (if it is bash it down out of the way or drill it out/ remove it and install a new one or an expander if you like)
      If its carbon check the expander plug is not loose and not just being pulled up the steerer. Also if it is a plug check that there is an air gap/space between the top of the plug and the bottom of the top cap of about 3-4mm if not all you are doing is squashing the top cap to the the top of the expander and not pre-loading it. You can check both plug issues by dropping a spacer on top of your stem and trying to set the pre load, if the creaks/movement go away then there wasn't sufficient gap, you can either cut 3-4mm off the steerer or put a short spacer on top. It the issue remains remove the top cap and spacer and you will be able to see if the expander has been pulled up, in which case fiber grip the plug and re-install to torque spec.

    • @Bikey_McBeardface
      @Bikey_McBeardface 2 роки тому

      Additional: Inspect the steerer especially around the bearing seats. The "ring of death" where the races bite/wear into the steerer tube is something that can cause this issue (even on aluminium ones).

    • @Pesmog
      @Pesmog 2 роки тому

      In addition to the other comments here, also make sure you are doing the final tighten on the ground as shown in the video and not on the bike stand. If necessary have someone pushing down on the handlebars so that the steerer and bearings are compressed with a real world load when you tighten the screw. 👍 I always re-check it after a few miles riding as that allows everything to bed in properly.

    It would be good to use a headset that isn’t brand new perhaps for a video like this. Show us a one that’s full of grit and has seen some wet weather & dry dusty trails and had a few washes and is in need of a clean and re grease. 👍
    Might be good to show how to inspect a carbon steerer tube for signs of damage from being ran with a loose headset for too long and also explain the importance of always clamping the stem where the expander tube is. Example don’t leave the steerer uncut if running the stem slammed as low as possible etc…

    I've always worked with aluminum frames and steerer tubes in the past, so any headset work has included the application of grease. Is it correct with carbon frames and steerer tubes that everything is assembled dry, no grease or any other compound? Can a small application of grease to act as a moisture seal damage the carbon?

    Have you (anyone reading the comments) ever thought about, or come across a cool mod that replaces the spacers? Like if you wanted to drop the bars down the steering tube, thus resulting in more of the tube being above the stem, without having to cut the steering tube and without just leaving the spacers above the stem, making the headset look stupid. For example, a part that reaches over the stem and adds more mounting space infront of the handlebars? Just curious to see what people have come up with.

    Is it possible for a bike with mechanical groupset to be setup fully integrated (all cables hidden). What could be the possible downside of doing that?
    And can you do that to any bike frame as long as you will use an integrated stem/handlebar?

    • @sbccbc7471
      @sbccbc7471 2 роки тому

      It's only possible if:
      1) The frameset runs integrated internal routing in the first place.
      2) Said frameset is compatible with your mechanical groupset (not all mechanical groupsets are compatible with all framesets with integrated internal routing).
      Otherwise, don't even try.

      On my MTB there are two ways of solving this problem with squeaking brakes
      - cleaning it with alcohol, sanding the pads slightly and reinstall everything
      - or descending a hill steep enough to get the brakes near 230 to 250 ° C (colour of the rotor: yellow to brown, blue (300°C) is not necessary) and the squeaking is gone
      Method 2 makes more fun

      It depends on your flexibility. Until you are sure that you can ride with a lower stem, you can just move the spacers to be on top of your stem, instead of below it. After you are positive you can live with a lower stem, you can remove those spacers and cut the stem. (once you do that, there is no going back) Just in case I become less flexible, I kept a 2mm spacer above the stem. Some people keep a 5mm spacer there.

I'm an older rider starting back after a 10 year break. This bike exceeds my capabilities and has been easy to get comfortable riding. I'm mostly on easy trails with almost no street riding and have not been disappointed with the performance of the bike. My fitness level is far below what I previously rode with and because of that the mileage is going on the bike slowly. While I'm losing weight slowly, the bike seems to tolerate my 220 pounds just fine. The bike has been used by several family members ranging from 5'5" - 5'9".
