In line adjusters

raymond82

Hi,

Every time I put my bike in the back of the car the adjustment of the rear derailleur is screwed. I've noticed this is because the in line adjuster loosens up, is this normal or does it mean that the adjuster is broken? I just wanted to be sure before buying new adjusters.

check that the cable outers aren't 'wound up', if you hold the adjuster and pull the outer away from it you should be able to turn it to relieve any pressure to rotate the adjuster

otherwise...

mine have rubber o-rings to stop the adjusters rotating due to vibration, if the ones you have are just metal i'd try applying just a smidge of low strength threadlock, it'll still allow you to adjust but it should give enough friction to prevent movement otherwise

loctite 242

That's a good idea!

Expensive stuff though, this loctite. I'll look for it in the local hardware store. For what other screws do you use this, also for crank bolts etc?

i use it for cleat screws and a few other things, a small tube lasts a long time, the bigger sizes get pricey, but even for small tubes there're big price variations

this should be equivalent... http://www.amazon.co.uk/Thread-locker-M ... _sbs_diy_1

you could use something else, a bit of teflon tape might be enough (plumbing supplies)

Thanks for the link! I also saw that the price differences for small bottles are huge but I found some nice deals on ebay.

I think should also have teflon tape somewhere but if the loctite can be used for other things too maybe it's a good investment. This sounds a bit silly, but does the loctite also prevent screws from not coming loose? I usually use anti-seize on almost all screws and bolts and the loctite seems to do the complete opposite...

sungod

anti-seize stops things corroding, especially where there are two different metals (often the case with bb, pedal threads, rd hanger bolts, alloy cage bolts etc.), but it's not typically designed to stop things coming loose, really for things that you tighten fully enough to stay put

loctite 242 just stops things coming undone accidentally, but it's weak enough that they can still be moved, just don't use too much on adjusters, put a teeny bit on a toothpick, dab onto the thread, it's better to use too little, you can always add more if still needed, you will be turning by finger grip only

Thanks for clarifying that!

I found a product that's being sold in the hardware store, I'll get it tomorrow with at 25% discount voucher!
