So for someone coming from a SPD pedal - PD-M520 to be specific set on the lightest tension - and thinking about the Zeros would the unclipping force be a whole lot more? I actually don't think I'd mind a lot more force to unclip but what I'd like that I don't get with the SPD is a very positive unclip if that makes sense. The SPDs seem sloppy with the start of the unclip and finish of the unclip being somewhat vague. What I'm looking for is a very quick and distinct unclip.
