There HAVE been a couple of times in spinning class recently where I had to unclip because my Sartorious was aggravated and being clipped in caused pain - but I think it was related to exercises I did prior to class. I don't do those anymore on riding or spinning days.
I am leaning toward having my LBS switch my pedals for me this week on the LHT and trying it out before my Gunnar comes. If there are no problems, then the SPD pedals will go on the Gunnar at that time and then I just might put the BMX pedals back on the LHT for a period of time. Or notThey really are different bikes and I do like the BMX pedals. Will still talk to fitter about my SPD dual-pedals.
My hands/grip are quite weak - without an actual work station I do not think that I can use a pedal wrench to unloosen my pedals. I do want to be able to do this simple task myself, but I cannot even open jars without a great deal of effort (if at all) so I am not going to fool myself that I can unloosen pedals without my bike being held by something stationary.
