After 20 years of spannering MTB, Road Cross and Tri… and having tried many “tricks” / “tips”, i have ended up here:-
If the chain is heavily contaminated (every 2-4 weeks of dry riding) or after every wet ride…
Kerosene in a park chain cleaner (toothbrushed do work, just messier and less effective / /more time consuming… )
use until the chain is clearly cleaned of residual oil / build up…
Flush chain rings and cassette to rid the kero from the bike… its pretty agressive stuff to oil… i.e. bearings…
Re use chain cleaner with armourall heavy duty wash, I use a good table spoon worth in the cleaner here… (or similar)… run the chain thoroughly through that, add ing water to the holes in the top of the cleaner until all the green wash in the clenaer has been picked up and run through the chain… this often takes 3-4 top ups with water in the cleaner until…
hose off the transmission a couple of times during this…
By now the chain is stripped of all oil, but covered in water…
So i invert the bike and dry the transmission with an old towel… not too carefully…
Now I apply WD-40 or any other water dispersant, spraying onto the inside face of the chain nearest the jockeys, running the chain backward at least one full revolution…
Then wipe off water and dispersant, with the towell…
Finally i apply Morgan blue race oil again to the inside of the chain whilst back pedalling, running one loop with the tip of the lube bottle at the inner outer plate on one side, and then again on the ither side… (as you look down on the chain)…
Then back pedal it 30 or so rpm and wip off all excss from the out seid of the chain and rings…
After one short dry ride / rollers session for more of the oil to have bled through the chain, si i again wipe off the excess which has migrated to the outside of the chain to reduce the amount of dust and dirt the lube will catch…
This will normally be good for 300-500kms (1week) of dry riding before a reapplication of oil is required, again the new oil witll displace the old dirty oil and is wiped off… every 1500-2000kms i degrease, unless long wet ride etc etc…
This sound all very long winded but its a quick process and has given me the best perfomance to date…
PS i have tried many dry lubes and whilst handy off road, the wet lubes simply run quieter and smooter IME…
All the best.
