I've handed out paper towels to 4-5 people this year and they were all delighted.
Less practical: the group I ride with did a 200km ride, with one member having a nice shiny case attached to his bike where the pump might go.
When they finished he smoked his cigar.
It’s a hassle, but doing 2 at a time means the admin is much reduced.
There is a huge amount less dirt and grease in my life now. Even when I change it to re-wax it I don’t get dirty. I probably get 2-3 weeks, 500-600km out of each waxing.
I already have some alcohol wipes in my bag as part of an emergency medical kit. I'll add a few more for grease emergencies. :-)
