But the angle of the shoe in the new pedals was enough that the crank arm brushed the inside of the heals. So throw a 2mm spacer on the "short" pedals, adjust the cleats on the corresponding shoes and ride off into the sunset. The distance from the shoe to the crank arm wasn't the problem. It was the angle of the shoe in the pedal. It be honest, I doubt that I would notice a difference of 2mm in shoe/crank spacing. -- Cheers, John B. |

I still use old-style clips and straps, because I want to ride using any pair of shoes. But a pair of sandals I bought last year slightly brushed the chainstays on one bike. So I took the sandals to my bandsaw and removed about 1/4" from the inside edge of the sole, at the heel. It didn't affect the appearance of the sandals, and it solved my problem. I know it's not an answer to your question, but it might remove your frustration. If I sawed a quarter of an inch off the inside of one shoe it would probably become a sandal :-) I fixed the "problem" by realigning the shoe cleat but the question is/was do Shimano pedals really vary that much in alignment. I've certainly changed pedals before with no noticeable misalignment. It is a bit humorous as when I complained to the shop that I preferred the old model pedals I was assured that these "new" pedals are much superior to the old models :-) -- Cheers, John B. |

So are you saying that the cleat was rotated more in one shoe (in which case the obvious answer is "Rotate it - it doesn't bother you in the other set of shoes") or that the cleat receptacle in one set of pedals was rotated a bit such that shoe-pedal combinations that worked well together ended up rotated if you swapped the shoe or the pedal? Or maybe everything else was just fine, but with the wider pedal, you cleared the crank by 1 mm and the with the narrow pedal, you have -1 mm clearance. |

What I did was to remove a set of Shimano M530 pedals from a bicycle and replace then with Shimano A530 pedals. A pair of shoes that I have owned for several years and used with both the M530 pedals as well as a set of M324 pedals on a 2nd bike, when used with the new A530 pedals were so misaligned that my heels brushed the crank arms. As I believe I mentioned, this is not global warming but I wondered is this was something unusual as I have frequently switched from bike to bike, or to put it another way, from pedal to pedal, with no previously problems. Or maybe everything else was just fine, but with the wider pedal, you cleared the crank by 1 mm and the with the narrow pedal, you have -1 mm clearance. No, with the shoe essentially straight ahead the heel clears the crank arm by substantially more than 2mm :-) -- Cheers, John B. |

Well, the two bikes in question have cranks marked SR Royal and FC-8400 and look straight :-) I will make a serious look at them later today but the difference seems to be the amount of play in the pedals (using the same shoes). It appears that the newer pedals have a very limited amount of play, i.e., ability for the foot to twist or swivel, than several other pedal sets I have on hand."Float" I believe it is called in some descriptions. (note: I am aware of the two different shoe cleats SM-SH51 and SH56 ) -- Cheers, John B. |
