If you're pedaling to the goods, the Endura SingleTrack Lite Shorts have the features--and cut--that'll suit you. They're long enough to cover the top of knee pads without leaving a gap, but not so long to be mistaken for knickers. They're stretchy and as secure around your waist as you want, but they're also baggies. These come without liners but are compatible with Endura's Clickfast™ system, so you can go for another lap in comfort.
