Take care of your knees, quadriceps and calves in colder conditions.
They will return the favor.
You've only got one set of pistons. When it's cooler outside, slide on a pair of Kneekers™ in either CoolMax© EcoMade® or Merino wool. Your legs will thank you. When we developed Kneekers™, the utility was good enough that we decided we weren't going to mess with leg warmers. If it's that cold out, we scooch our Kneekers™ down a bit and run a taller sock for complete leg coverage.
Keep at least one set of Kneekers™ in your kit bag at all times. You'll find what many of the world's top riders have realized: they are a very good hedge against just about any cold front you might be pedaling toward.
