I have a set of M-324's on my Felt Nine Comp. Very convenient. Any real riding I always clip in. For a quick run somewhere the platform side is handy. My set came with the multi release clips. I have a pair of Nike shoes and a pair of Keen Commuter's (sandals). LOVE the sandals, seldom wear the shoes anymore.
