Been using Mavic Crossmax SL (Time ATAC's rebadged) on my Synapse for a wee while now. While the rotational float is great (i.e. shifting your heal left or right) they are prone to allowing your foot to tilt outwards and inwards as I don't think the cleat is contacting the pedal body but just the bars, leaving room for them to tilt. Plus, they squeak which seems to be a problem with most Time ATACs.
In short, what are the rest of you SPD'ers using and any recommendations for a SPD pedal for a road bike? Thanks.
