    Thanks. I've done it successfully. Went into my LBS for a chainlink connector and cable crimps, told the guy what I was doing, he wasn't very happy as he's being doing all my repairs for a number of years now, I've not often been happy with the standard of his work, but now I can do some of it myself, that's just great.

    I typed this list of instructions I took down from the video. It's word for word what we just listened to so up vote this so we have both options when you make it out to your garage.
    1. Undo Chain
    2. Detach cable from rear mech, pull out cable
    3. Unscrew main rear mech bolt
    4. Screw in new rear mec, watch for cross threading
    5. Tighten B tension screw behind the stop on the hanger should be 1 cm from top jockey wheel and big sprocket
    Removing Cables
    6. Gear down
    7. Roll back rubber lever cover and remove cable
    8. Insert Cable through the same cable guides etc the original came from
    9. Screw the barrel adjuster in entirely and turn it back one rotation
    10. Tighten the crimp bolt on the rear mech onto the cable, having pulled the cable tight
    11. reattach chain
    12. (Chain position Smallest cog in the rear and biggest ring in the front) Align the jockey wheels to the smallest cog using the H screw. Screw clockwise to move towards bigger cogs.
    13. (Swap to biggest cog small ring, if you cant get into the big cog its either lack of cable tension or the L screw push down on the mech/pull cable to test the tension first) Use L screw to align rear mech jockey wheel to the big cog
    14. Adjustments - starting from the big cog try to gear into your small cogs. If it doesnt shift smoothly try loosening the barrel adjuster. Adjust till you're satisfied.
    15. Cut the cable leaving one inch of cable hanging out and add on a cable end cap and crimp it on.

    Well, I just spent about 8 hours over 3 days trying to figure out why I could not adjust the derailleur. Maybe he said it in this video, but I did not hear it. Before you tighten the derailleur, or mech as he calls it; it must first be rotated as far as possible to the rear of the bike, then tighten it. Dumb yes, but who knew the first time? I can see now that he's holding it in the rear position, but that was not obvious until I found my own error.

    Thanks guys for this video. I was struggling for hours trying to get the gears to downshift with a replacement medium cage (to cater for the 32 cassette) SRAM Force 22 setup. This video mentions replacing frayed / old cables so I reluctantly due to the internal routing replaced the cable and now it works like a dream. The old cable was getting was caught up inside the sheath and not allowing the derailleur to freely move.

  • @leemoore8154
    @leemoore8154 8 ปีที่แล้ว +53

    I wish we could all have the same standard when it came to what "lowest gear" means. At 1:55, Dan talks about shifting to the "lowest gear," but the video shows him shifting to the smallest cog, which I would generally call the "highest gear" (since it's the highest gear ratio).

    It's probably just a matter of adjusting the cable and the stop screws. You might need to change your rear mech to accommodate the larger cassette, so it's worth taking it to your local bike shop to get it checked out.

  • @drouleau
    @drouleau 8 ปีที่แล้ว +8

    Good video, but adjusting the high/low screws is much easier (at least in my experience) with the chain off the bike and using your hand to push the derailleur in/out while adjusting the screws. I also do this while adjusting the b-limit screw with the chain off the bike to get a rough estimate, and then fine-tune that once the chain is back on the bike.

  • @gcn
    @gcn  11 ปีที่แล้ว +2

    If the chain is jumping around just after installing a new chain it's most likely that (sadly) you need a new cassette too. Unless you manage to replace a chain before it gets too stretched you'll end up wearing the sprockets on your cassette and need a new cassette at the same time as a new chain.

    • @djarvils
      @djarvils ปีที่แล้ว

      This is how every bike shop scams customers!!! They tell you that chain is overused (even if you have no any problems on that). You agree to have a new chain. Then you realised that this was bad call and the guy only then tells you - you need a new cassette too.
      I have learned how to keep the chain and shifting as clean as possible. After 20 000km with my new Rose Reveal Four I still have no need for new parts.
      When I'll have a feeling that chain is done then I'll replace chain and cassette at once!
      But thanks for the video! You encouraged me to try to fix this issue by myself!

      There is usually a small "pip". On the derailleur which engages with a slot on the hanger. A spring keeps the mech in the correct position.

  • @mybluebelly
    @mybluebelly 7 ปีที่แล้ว

    Nine times out of 9 - all you need to use is the --- BARREL ADJUSTER --- (seen at 4:30) Turning this knob CLOCKWISE will make your chain move closer to you or walk down the stairs if you will. Whenever you get the hang of this, you will easily be able to remedy small glitches and finetune / index your drivetrain. Keep in mind most bikes also have a barrel adjuster on the handle bar so if you`re a real handyman you can adjust this while out riding your iron horse. If you don`t understand how the two small stop screws (L&H) work and you already started messing with them you will likely get a lot of issues so just go get some technical help :)

    Small tip: instead of using an end cap on the shifter (or brake) cable you can also use electrical shrink tubing. Looks better in my opinion (you can chose your color) and it has te same effect (the cable doesn't unwires itself and doesn't corrode at the cutted surrface).

    @CanAmSteveUK 11 ปีที่แล้ว +1

    This was a bit rushed, but can I stress that TINY adjustments are needed for fine-tuning? Like 1/8th turn. Before you rethread the chain (skipped over here) push the mech in and out and roughly adjust the high/low screws as it's a lot easier without the chain in place

    The direction of the barrel adjustment (counter/anti-clockwise) was easy to understand in this video, but in many cases saying clockwise or counter/anti-cw isn't always easy to determine. Esp with the mid cable adjusters where it's easy to confuse which direction is CW. Is there a thumb rule about knowing what direction is supposed to be CW?

It wont even go from 8 to 7. My problem is that, when I adjust the H and L screws, I cannot see ANY part of the derailleur moving AT ALL! I was surprised at just how much movement I saw in the video when you turned the H-screw. Am I looking at a new derailleur here? I have checked the hanger and it is perfectly straight.

    Hi. I just subscribed. I've never really watched a how-to video regarding bicycles... I'm purely self-taught... Those sprocket things you talk about, if it's the same thing as I'm thinking of, I call them cogs. The derailleur (I only learned that word a couple of months ago) used to be called the gear changer.
    You've opened me up to a lot of new vocabulary today. The thing is, I'm good at fixing bikes. But when I go into a bike shop to get parts, I describe the part and they never actually tell me the names and I buy everything except inner tubes and break cables used so they never have a box...
    Hey, imagine doing professional cycle maintenance without knowing the names of the parts haha.
    Anyway, what do you do if you have a bike and someone's messed up the alan key bolt that holds the handle bars in place? My alan keys just spin now, doesn't undo it and the next size up doesn't fit... It's in there proper good and tight too, tried everything I can think of except possibly drilling it out...

Overall, the video tells you all you need to know. More dirty oil on my bike though!

  • @Kristinapedia
    @Kristinapedia 9 ปีที่แล้ว +1

    My gears don't shift correctly. I have to shift two or three times to go 1 or 2 gears. Then the bike decides to change gears whenever it wants after that. Usually when i'm going up a hill or when I least expect it. i've almost gone head over heals a few times. Normally I'll shift twice, bike will change one gear, then I'll shift back once to be "even". It's annoying. is this worn cables?
    coincidentally my derailleur just broke two days ago, was shifting to an easier gear for going up an incline and POP! thankfully it wasn't terrible and I was still able to pedal so I didn't fall. I'm wondering if I should attempt to change this myself as it'll save me labor. The bike is a fuji nevada and it's at least 12 years old. It's also my transportation as I don't have a car.

    • @Lucian-M.M.
      @Lucian-M.M. 6 ปีที่แล้ว

      Since you couldn't figure why the gears are not shifting correctly, my advice would be to take it to a professionist. My amateur mechanic experience tolds me that when you don't know what are you doing, it will eventualy fail somewhere. Or, how someone said previously, it will make you lot of nerves.

    I bought a Shimano rear derailleur to replace the offbrand stuff that came preinstalled on the bike but when shifting to the largest rear cog, the derailleur interferes with the spokes, is that because I have a long or medium when I should have a short one?

    I had a new carbon frame with internal cable routing. There was too much internal friction and it shifted like garbage for over a week and no matter what I did (cable lube, lengthening cable housing for less extreme angles, etc..) nothing helped. Finally the problem worked itself out and it began to shift fine. I have no idea why it got better. Are there any tricks for sluggish, inconsistent shifting with internal routing? Or does it just need to be broken in? Thanks!

    question - I had to replace the rear bike tube, when I put the wheel back on, the shimano was offset about 2 inches out from the bike! I don't think I bent it, is there some alignment that I knocked out or something? The gear selector thinks I'm on the highest gear but the shimano has the chain on like the third cog, and wouldn't move any further to the other 4 cogs. Is there some gross adjustment that I'm not seeing to get the shimano back even close to the cassette?

    Can you please post a video about how to put a 9 speed cassette on an 11 speed free-hub

    Why not tub glue vs tub tape. Just a suggestion. I've been using Tufo for over a year and had a good experience with them. It's sometimes daunting to go to tubular because of the gluing. Also tub vs clincher maybe.

    Brand new Scattante CX 350. When I'm in top gear (largest front ring, smallest rear) my chain is thrown off whenever I stand up to accelerate.
    I don't believe that I'm pedaling too hard, and this is a new bike.
    Front derailleur is Shimano Sora and the guys at the bike shop have no idea what is going on.
    Thanks for your help!

      Philip Gragg it either sounds like you're putting out too much power and throwing the chain off when the frame flexes or that your front mech is a bit out of adjustment.

      It could be the derailleur limiting screws aren't set up correctly for either the front or the back.

    Thanks for this! I have a ticking sound in just one rear cog. The bike is brand new and gear indexing was pretty good before a rather aggressive ride in the woods... Oops. I think I must have a bent rear mech hangar or derailer cage... is there a GCN video to save me from this issue too??!

    Hello,
    I have a slk shimano derailleur. It is all brand new, with cables. Now that it us broken in. When I am in my 2,3, and 4 gear it is making a noise, like it is struggling. All the other gears I don't hear it, so if you can please help with any tips on what to try next. I have adjusted the cable, because I thought it might have been too tight, but it still makes that sound in those few gears. I was thinking maybe the b screw, but from what I've seen in a few other videos that won't do much, for what I need.
    Any advise will be grateful, thank you :)

    Following my earlier question about the rear derailleur, I failed to say that the lower part of the derailleur is hanging to the rear under the tension of a spring? I have fitted a new cable and outer, Do I need to tension the cable which will then pull the lower part of the derailleur to 'hang' down and so in the correct position - if you understand what I mean?

    I know its a old video, but I need to know if I should use anti seaze paste on the rear deraileur screw or assemble it dry?
