I'm so jealous right now, as it's hovering just above freezing right now. By the time the bike gets warmed up, my hands are too cold to ride anymore!
If it's +45F and sunny I can go for quite a while with my winter riding gloves and cheap USB hand grip warmers. Keeping my fingertips warm has been a challenge on colder days. So I ordered some handguards as that should help keep the air blast from hitting my gloves.It was 46F when I went out for a ride this morning - 55F by the time I got back. But that's about the coldest it get's here in Monterey Bay - and bright sunshine made for some nice riding.
