I tried the speedplays but have difficulty clipping in with the tandem. I could not start an uphill and pedal not clipped in. I changed my pedals with my road bike and that was better but ended up going to mountain bike shoes and pedals for the tandem and I am much happier. Plus walking around is so much easier, holding the bike is great and I can pedal unclipped if I need to. Pedaling unclipped is great when starting uphill and that allows me to clip in once we are moving with enoug speed.
