Cross levers! Tektro RL-740's, which were the only levers I could find that'll work with long pull brakes. Wrong clamp diameter for the Albatross bars, but some strips of beer can aluminum and electrical tape closed that gap right up.
I like riding up in the bends when fighting a headwind, or whenever I feel like really boogying, but I was nervous about cranking hard while my hands were nowhere near the brakes. I also ditched the cork grips, which were conflicting with the black/silver color scheme that the bike's got going.
Hey Richard, I think that your F4's the same model that my father-in-law is currently using to cross the continent. He left Seattle almost two months ago, and is now within 300 miles of DC. He loves the ride.
