Dry Chain Noise..

[betty swollocks]

Boon, when in the large ring, as you move to the larger cogs at the rear, at the point the chain stars making that noise, try clicking the shifter as if shifting to the small ring, but only push it until it clicks once rather than all the way, it should move the mech a bit without shifting to the small ring, this is known as trim, and it's very purpose is to avoid noise!



I don't disagree with the principle, but IMO you should be able to use more than half of the cassette in each chainring. I use 7 out of 9 possible ratio's in each the big and small rings and I believe this to be perfectly acceptable practice. In fact I often even use the 8th largest cog when in the big ring when pulling away and I then shift up a couple.

Of course you can do it if your derailleur(s) allow, but, the straighter you keep your chain, the longer it will last and the more efficient will be your pedalling.

I accept your point, but at the end of the day, the parts are only going to last so long, you can either accept that and compromise or you can minimise wear at all costs and quite frankly I cba to go to those extremes, it is just not practical IMO. As for the efficiency, you won't notice either way unless you are an absolute beast, I would wager I would lose more time farking about shifting than I do from running the ratio's I choose to run!

Fine, great, go ahead.
I tried to answer the OP's question. The OP, to my interpretation, is obviously new to cycling or using derailleur gears and needed a few simple hints/rules to follow. Once you know the rules, you know how and when you can bend them. You obviously do......

OK.. I did up end the bike and and check for kinks in the chain but nothing looked wrong so while the bike was there I did put some Scottoil with my finger on the chain and I have to say it was a lot less noisey so there could be a problem with not enough oil on the chain.
I did see some dry lube in Decathlon but I didn't know the brand so I left it.

Its funny how you day goes...
I was going to get some dry lube from Wiggle as they send to Spain, but lube oil its not on the sending abroad list as some things are excluded..... but nor is a footpump so how daft is that.
I will try chainreaction or evans and see what happens.

I am working the next few days but as soon as I can get out I will some trim and see where we go..
