I am a road biker and after moving to Montana winter can be a bitch for a road biker. I have a hybrid that had clip pedals installed. I never liked the feel so I bought a new pair of mtn bike shoes and SPD pedals to take advantage of the inset design of these shoes... OMG I still can't get over the comfort of these pedals. I can get off the bike and walk like a human not like a newly shoed horse like with Look and Speedplay pedals. Don't get me wrong those pedals have their purpose but for commuting or biking back roads of anywhere these are the way to go. I wasn't worried about saving every gram of weight and so far these pedals have performed right out of the box. The pedals are adjustable and I may fine tune the release if I get around to it but then again, maybe not. Great product as would be expected and the cost to value is tops. I have ridden the MS 150 a few times and will be wearing these for sure.
Nothing much to say about these pedals. Not the lightest out there, but they work just fine. If you just need a pedal and aren't counting every last gram this is a good way to go.
Shimano Pedal Dynamics (SPD) are the pedals I used when I went clipless 15 years ago. I wore out 3 set of SPD's, never found a rebuild kit. 10 years ago I switched to Crank Bros Eggbeaters and Candy, for which I have rebuild kits ($10) and rebuilt 1 set. Cleats wear out before the pedal bearings. I remember a few episodes of SPD's jamming on engagement/disengagement. Scary when the pedal won't let go of your foot. Crank Bros are rebuild-able and smoother engage/disengage.
These are my first pair of pedal that I clip into. They certainly help out on long rides and increased my overall speed. I ride the paved river trails in Orange and Los Angeles Counties and these are working well for me.
