Here's a link to the listing for the SH71 road cleats w/pontoons: http://www.performancebike.com/shop/...slisearch=true

Most of the info I've seen says they are a multi-release cleat with 8 degrees of float, compared to the single-release, 4-degree SH51's I'm currently using -- I just don't want to get them and then discover my current pedals aren't usable.
