Time ATAC XC vs XS - What's the difference?
I bought a bike a week ago (and have only taken it out in the neighborhood and one mini-ride... damn weather/work travel). For the time being I stole my Shimano M324 (flip-flop platform/spd) pedals from my touring bike, but I want to pick up some clipless. After talking to the LBS folks, friends, and reading here, I think I'm going to ride Time ATACs, but I can't figure out the difference between the models!
There are a couple different models of XCs, with different materials/weights and features. I'm leaning XC4 so I can adjust the release tension. As for XS, they have similar specs and adjustable release too (the Aliums don't).
Does anyone know what the difference is? I don't see the XSs on the Time website anymore - are they being phased out?
