When and how tight should you adjust your clipless pedals? I'm new to clipless pedals. I got some Shimano ones, with Specialized MTB shoes. They are an SPD clipless pedal, and the shop adjusted them as loose as they go to unclip from them. My questions are:


How tight should I adjust them? I'm not unclipping unexpectedly from the pedals, and so far (crossing fingers) have not had any crashes due to the settings.
When would you want to change the tightness of the pedals? Based on terrain? Riding? etc? Do you ever really adjust them?
Two guidelines:


If you're unclipping unexpectedly (happens most often when pulling up) then increase the tension.  That means turning the adjustment bolt clockwise to increase the spring tension.
If you're having trouble clipping in/out then loosen the tension until you can easily clip in/out when you need to.  Turn the adjustment bolt counter-clockwise to relax the spring.


If you're not having either problem, then no need to adjust at all.  If you're having both, then you'll need to choose which is more important (probably clipping in/out) and adjust for that.

(It's been a while since I used SPDs, but I think double-sided pedals have an adjustment bolt for each side -- make sure to set both the same!)
