Well, the outer nut holding the cage in place sheared off after a hard but typical strike. Stripped the bolt making the pedal useless. Not to mention, the pedal inside the cage is a very low level pedal. On its own, probably $40. The cage is not worth $100. Look elsewhere.
You're going to slip off if your wearing a slick bottom shoe. You'll probably feel the cleat in the bottom just because it sits above the pedal a little bit. If you want a pedal that has "both" options, look into this one. Ive had it for a few years, its got the cleat and the flat pedal. I rock it in Flip-flops and clip-less shoes..its the best of both worlds.
I've had 2 pairs and on each I knocked the outer body into a rock and it bent the cage and spindle, making it very hard to unclip and impossible to clip back in. I went to Time Z pedals and won't buy these again. There are better options if you want a large platform and clipless ability.
Pricey but worth the extra swag! The grips are good on sneakers and boots, and the platform is pretty solid. I originally bought the M424, but in less than a year the plastic cages got chewed up from leaning and trail debris. Clip in easily on both sides and adjust just like the M540
9/16 inch diameter x 20 thread per inch. Unless you have a really old pair of french cranks or a kids bike these pedals will fit. You use a 15mm wrench to install the pedals, a special "pedal wrench" can make it easier on some pedal types. Each pedal will be stamped with an L or R for left or right which is the side of the bike the pedal belongs to (while in a riding position, riders left or right). The right pedal is right-hand threaded, the left is reverse threaded. An easy way to remember this is that to tighten the pedal, turn it the same direction of the crank to go forward. Be careful removing old stubborn pedals and the placement of your hand, many knuckles have been damaged with this operation.
