I'll be sticking with the Squirt wax I always use. Admittedly,it's better in the dry than wet in my experience,but it doesn't leave residue all over the rims, cassette and chainrings the way wet lubes do. And I carry the sample bottle they sent me with a top up supply should I need it.
Chain care is then a simple case of brushing the chain which removes the loose flakes of wax, taking the dirt with it, before reapplying Squirt if necessary.
Right now, I'm just glad that Amazon have finally notified me my long-overdue 23mm Conti GP4000s tyres are available for collection, despite the tracking showing TNT still had them sitting in Belgium for the last week as of this morning! Now I have the option of replacing my 25mm 4000s's to allow my new mudguards to go on.
