I used Castrol wax as well and swear by it. Make sure you are applying it AFTER a ride when the chain is hot, the wax and white residue are not so bad if you do it that way. With the chain expanding due to the heat you get into all the nooks and crannies. Only balls ache is if you are cold and wet and just want to get inside. Quick wipe of the chain before you head off out next time gets rid of any excess and you are safe in the knowledge that any you have added has worked it's way well into the chain and rings in particular all the time it has been standing since your last ride out. I suppose the same advice rings true for WD40 which i have also used in the past and had no problems with. Regards ScottyB |
