track/street bike: metal All-City double strap/double gate clips, All-City standard track pedals
rando bike: nylon All-City double strap/double gate clips, MKS GR-10 pedals
The nylon clips feel noticeably more comfy and secure over any distance, though I'm pretty sure the pedals are a contributing factor.
The metal clips function ok, and are way more photogenic. Perfect look for my black and gold Big Block.
BTW both sets of "All-City" clips are embossed with the CKC logo.
