I went throught this decision myself and after some substantial consideration, including looking at Keos, went with the Time RXS Ti.

Why? More adjustability, lightness, and bang for the buck. The Keos are essentially non adjustable. The Speedplays are adjustable for float but contrary to FoxFarm they are not as adjustable as the Times. One of my biggest issues now is that it takes time to try out the many possible adjustments.

The Speedplay pedal is small and cute but the cleat is large and ugly. The bearing action on the Speedplays is not what I would have expected - that is it does not freely spin using hand pressure. Does this really tell us anything? I really don't know but it surprised me.

The Times are also the lightest in the Ti version when you factor in the weight of the cleat. Well I think they are since Speedplay won't tell you what their cleats weigh which tells me that they are not light. The Keo Ti's are 5g lighter but given their price and the lack of adjustability they were no longer in the consideration. Remember Speedplay gives you weight per pedal not per pair.

There are alot of other reasons the Time's are the best including platform area, cleats that you can actually walk in comfortable (le Cafe Cleat) and the lowest height off the pedal spindle but I'll let Time provide the explanation:
