Shimano Deore LX (M770) pedal release issue
Issue is cleats releasing with very little pressure or twisting
applied, on both sides. Even when, for example, I stick knee out to corner. Tension is turned up to max. on both sides and R/L (clockwise toward the "+"). Same problem with standard cleats and newer multi- release cleats. Pedals are less than a year old. Could this be a symptom of worn cleats (I cant recall if this got progressively worse with original cleats)? Any tips to get these more secure....nervous going downhill esp.? Thanks Peter |

Yes, it can be a symptom of worn cleats. Also check to make sure there is not something in your shoe preventing full engagement, like mud around the cleat or a rock, etc. -- Jay Beattie. |

True Chalo, No it's not. If you are applying a large upward force on your pedal, you foot will come off unless it is bound to the pedal. TdF riders don't use clipless because they are making up for "poor form." Clipless allows for better energy transfer when sprinting, climbing, etc. Do you think world-class track racers have poor form? (answer: no). This "problem" has made me think more about balance and body position and I hope improve in that area. *Still, I would like to know why these cleats are essentially acting like flat pedals. Is this a new problem or an old problem? If its a new problem, you probably have something stuck in your cleat or the cleat or pedal has worn out. If it is an old problem, it is spring tension, wrong cleat for pedal, cleat misadjustment or even hypermobile ankles. I've got hardware in both ankles and a mobile right ankle, so I can get unplanned release when pulling up hard with even a slightly used cleat because my ankle naturally rotates outward. I counter that with insoles to try to stabilize with exercise. If I had no cleat at all and big fat grody platforms, I just couldn't pull up. -- Jay Beattie. |

Having migrated over the course of many years from plain pedals, to clips and straps, to clipless pedals, back to flat pedals, I believe attaching your feet holds you back from developing all the refinement in your pedal stroke and bike handling that you would naturally develop otherwise.

That's why competitive BMX, trials, freestyle, and downhill riders have gotten along all this while without foot binding. There are probably cycling disciplines in which the elite professionals can benefit from having their feet attached to their pedals. You're not an elite professional in one of those disciplines, and neither is the OP, and neither am I. In strapping our feet down, we're not helping ourselves to victory and the lucrative endorsement contracts that come with it-- we're just forcing our feet, ankles, and knees to do things they otherwise might not do. And we're training our bodies not to maintain a steady footing or smooth pedal stroke, because how would we know if we were doing it wrong anyway? Chalo |

Whenever I climb out of the saddle, which is a lot. Even during regular pedalling, I apparently exert some amount of upward force because the flaccid velcro straps on my old shoes kept popping open on the upstroke. I also generate considerable force across the bottom of the stroke. And even when not pulling up, clips or cleats keep my foot centered over the spindle and aligned properly. They do not do that naturally. *Research has shown that even elite competitive riders spend almost no time exerting lifting force on the pedals. *That's why competitive BMX, trials, freestyle, and downhill riders have gotten along all this while without foot binding I don't doubt that seated riders generate very little lifting force on the pedals. I do not agree that a well trained cyclist does not apply a considerable amount of force across the bottom of the stroke (scraping gum off the sole, as they used to say). That type of movement will pull a foot backward off a pedal. With BMX, trials, freestyle and DH, your feet have to be free to dab the corners, etc., It is not road riding, and in fact, it is not the kind of riding that many of us do. BMX is the silliest position on a bike I have ever seen -- my knees would be somewhere around my ears. BTW, my brother is a state champ old guy DH racer, and he uses a cleated shoe.

It's not good. I ride a rubber pedal bike to the store and think its fine. I wouldn't want to ride it for 60+ miles over hill and dell, though. -- Jay. |

When I started commuting, I had to really get in shape just to do it, and I can't spend all day at it either (though plenty of times I get to work in a couple hours or so, and the sun is up and the coast beckons... :-) I rode for a couple of years basically pushing myself almost every minute.

I rode an English 3-speed with 27" 10-speed wheels and no derailer as a single speed. No brakes on this one, BTW... and one of my favorite... no, my very favorite run had us walking bikes to the water tower above the golf course, riding down a few curves to the intersection at the top of the golf course, then taking a driveway diagonally, dropping off a dirt berm onto the cemetary, then hitting the gravel road the rest of the way down. All I can say is, whee! (But yeah - I liked to get a foot out to help balance on the fast gravel turns.)
