Tight spots in chain ?

[Kiwifruit]

I have a couple of tight spots in my chain....any fixes or is it replacement time?
Its done 50,000 kms.. Sprockets look OK.
Cheers.

[grog]

Replace it mate.

[gsxbarmy]

I agree with Grog, time to replace. And in all honesty, whilst the sprockets may look ok, if they have done a similar mileage - then I'd replace both chain and sprockets as there will be some wear in that time which will shorten the life of any new chain you may fit.

[Kiwifruit]

Yes would always do the chain and both sprockets.
Thanks guys.

This is the one I brought recently Col - very pleased with it so far.

i know about chain n sprocket all being changed together. BUT, i didnt last time. bad boy. sprockets just looked so good. i decided to buy a cheap chain just to wear out sprockets. EK, for $110, didnt even get x ring just the old skool o ring. my thoughts were get a few more ks then replace the lot. here i am now, 10 th ks later. havent had to adjust at all, still running sweet and sprockets look exactly same. im a fussy old prick and if i thought a problem i would change them. i really cant believe it . i was pissed off that my RK got tight spots, i dont think it was chain fault even though i read they had a bad batch. i blame the Wurth chain lube, just didnt work or protect. chain was rusty as inside. told before now using vmx castrol gear oil as lube. much better. bit more work but just all good. my EK chain is way down the line in their product strength, if the top ones perform as they say, should last forever when i get one. expensive, but if they last, all good. can of worms now opened.

I have to admit that i tried a few chain lubes. The aim was to keep the chain lubed and the  back of the bike clean. One time i was using a very light waxy race lube. I did a 700km ride one day. I stopped because i could hear the chain at slow speed when id done about 400km. I think i ruined the chain that day.
I have been using a Putoline chain lube that is quite wet and sticky. Makes a bit of a mess but keeps the chain moist. Too late now, i guess the damage has been done.

I'm paranoid about chains, I have been using the new engine oil I put in my RAV4 (20w50 stuff for years), (always a bit left after a service) I just apply a little each side of the chain on the inside every tank full of petrol, it is easy to wipe the rear wheel clean and to wipe the chain clean too. Engine oil is a cleaner as well as a lubricant YES?

[Andre]

Yes, engine oil is a cleaner. I wouldn't use it for lubing the chain as it flings right off.

I use kerosin (petroleum) for cleaning, wait till dried off, then apply a dry lube (S100) and let it dry a few hours (preferably over night). The cleaning is the most important part imo as the dirt works like sand paper.

[Timothy Spencer]

You need grease on a chain not oil. The grease needs to resist fling and water. Oil could all too easily get on the tyre tread.

[Leyther]

Grease = grinding paste, Don't do it!
Gear oil or scotoiler for me.

[KiwiCol]

For what it's worth, DID recommend 80/90 gear oil for their chains, not spray on lubes or grease, oil.  That oil grade is from memory, it's actually on the back of the chain pack & on their website. The DID chain info is also a sticky PDF on this site.  Have a read, even if it's just for another perspective on chains & lubes.

my 2p worth
i clean the chain with any chain cleaner i have then wash the bike once all dry i re lub with what ever chain lub i have .
replace the chain and sprockets every 18000-20000 miles as soon as the chain need to be adjusted after the 500 miles first adjustment.
i also replace the sprocket carrier bearing at the same time.
done me fine on all the 14's I've owned with no problems.

[Batkwaka]

On my chain driven bikes I use WD40 for lubricant. I get 80k/km from my chain & sprockets and they are still within tolerance when replaced.
Unless you clean off excess lubricant, any chainlube will become a grinding paste that an O-Ring chain doesn't actually need.

Interestingly I asked a respected race bike builder what he used on his chains.......he said CRC.
