With all the chain lube questions I have to ask
I have 5 bikes I ride often. I use LBS lube(s), tried WD-40, and all work well except 1 bike, Its a Giant OCR Touring.
I've had it for 2 yrs now, about 1200 miles total and it has the ONLY chain that I can't keep from rusting. I've cleaned it often in Diesel Fuel, Kerosene, WD-40, etc. I lube it often, in fact much more than any of the others. Last cleaning was 2 weeks ago. So I started out on a ride yesterday and I had trouble shifting. I looked down and it was rusty as an old barn nail. Put some LBS lube on it and it shifted OK, but Dang What do I do now. Replace It? BTW - I should comment that after I first bought the bike I noticed light rust almost immediately. Help !
