Shave? I do.
Started off doing it when racing cross; far easier to put embrocation on shaved legs in a freezing carpark, then far far far easier to get it off along with all the mud at the end. Carried on while road racing, same reasons really, especially when driving a long way home and no access to showers.
I wear lycra a lot to ride in and suncream goes on quicker too.
Plus, I prefer the look, being blessed with mad hairy legs..
People who get all excited about it are a wee bit silly; do it if you want to, don’t if you don’t, and it’s ultimately none of your business…
