My Crank Brothers 50/50 pedals have rails. You can change them out to change the color or replace broken ones. I spent a bit of time on a mtb forum of mostly young boys ranting about how the 50/50 pedals kept falling apart and losing screws. A few level-headed reviewers claimed that might happen if you beat them on rocks all the time but not otherwise. I find them to be very sturdy pedals that grip my shoes very well and are great for flat pedaling.
