High stack height and no good for actual off roading. Have them tightened fully and have unclipped several times in less than ideal times. Once on a landing of a jump flying down hill, both feet at the same time. The saddle came up to meet me real fast.
I like my S-Tracks but they're on their last legs after not particularly long and there doesn't seem to be any way to take them apart enough to service them.
I have those. Terrible pedals.
