Serious issue with rust. My chain rusts easily, and now I relube and wipe with WD40 often.

Bottle cage bolt rusted real bad and needed a dremel to cut. Was a cheap 'what was available bolt' [mu mistake there], and now switched to st steel.

Latest was pedals. I greased them well but they were rusted and jammed so hard that I needed an extra length of pipe on my allen key to get them off.

Garmin magnet disintegrated with rust.

The inside of my hollow BB is also showing rust. Now polished with a dremel.

Only on my road bike, so I presume it's due to sweat [not on a trainer either]. Nothing on my wife's bike either, and she doesn't sweat like I do.

Bike is just a year old too, and the pedals were put on maybe 6 months ago last.



Any suggestions?

WD-40 is not a lubricant. Stop using it on your chain.

Living in the tropics I understand what it is to get wet, really wet, far too often.

You can wipe your frame and external parts down with a coating of BIKE LUST or similar products. That will protect them a bit.

ALL threads MUST be greased. I would even put a super light coating of chain lube or grease on the BB30 axle and any other exposed metal parts. By this I mean putting some on a shop rag and giving everything a good rub.

Also, look at some penetrating oil. It can help with brake and der pivots and other places water can get in and you can't.

Bob, you misunderstood about the WD40.

I have only recently started using it to wipe down the 'exterior' of the chan. I wet a cloth and wipe, and don't spray on the chain at all. I use wet/ddry lube as per season, and this has solved my chain rusting mostly.

I did grease the pedals before putting them on, and was shocked to see the degree of rust. Actually Bangalore is very very dry, so it has to be only my sweat.

This time, I'll follow your suggestion and apply a thin coat of grease on the axle and exposed parts that are susceptible to rust.

What exactly is a 'penetrating oil'. Any suggestions on brands. All this is not easily available in India, and I might have to find local substitutes, or order online.

Thanks for the suggestion.

Got it.

WD-40 is a penetrating oil that will unstick stuck parts, some other brands will leave behind a thick lubricant that won't wash away as easily as WD-40 does. Also, the solvents in these are more aggressive which means it will eat away at more grime and the lube will penetrate further.

I've found this stuff from WURTH to be awesome but I'm sure there are other brands that would work just as well.

As Bob mentioned WD-40 isn't what you need.

After using various prepared lubricants for my chain over the years I now use a mix of mineral spirits and 30wt. motor oil in an approximate 60/40% mix on my chain. You can either remove the chain from the bike and soak and shake it in a container like a half liter jar or coffee can or use the mix in one of those scrubber tools and leave the chain on the bike.

Grease everything often and wipe your bike down with, at the very least, a damp rag after every ride.

Did you read what I had posted? Chain is not the issue. I know about chain cleaning and lubing. It's the pedals, crank etc that are getting horribly rusted.
