helmet + clothes - bike shorts

Seat and bike shorts.

An integral part of biking comfort.

After all 6 hours a day are spent sitting on your arse.

Recommended: an expensive pair of professional bike shorts with substantial padding. That way you don’t suffer chafing from any seams.

Then you won’t complain about your sore arse even after 8 hours ride on a bumpy road.

PS. Don’t know if this is obvious but take another pair.
