I suspect these are what mine are. When quickly taking these photos just now with my phone, again I am amazed by how smoothly they spin, no crunchiness, no apparent play when pulled outwards--a real achievement of the bearings when I think of how some of my old regular pedals before this with ball bearings and cones never felt this good for so long. I'm sure that I wasn't really doing much mtn biking with them helped by not being in mud etc very much.

and yes they do weigh a ton.
I seem to recall them costing about $80 or $90.
