is it possible to get spd pedals with a 1/2" thread

i have some xtr m952 cranks these take the regualr 9/16 pedal
i also have some xtr m951 cranks ( these came from usa) the 9/16 pedals from the above do not fit they can be pushed into the hole so i assume they are 1/2" thread :shock:

1/2" is less than 9/16" :?
If 9/16" pedals can be pushed into the hole, then I reckon the pedal thread is FUBAR'd.
There is no way shimano produced XTR cranks with 1/2" pedal threads.

if you read carefully, the cranks are XR not XTR. :?

There were those road Dyna-Drive cranks when Shimano produced another so-called innovation that thick pedal spindles would make you faster. :roll:
Along with metric pitch chains.

I thought they were 1980's though... :?

an the m951s must be 9/16 theres nothing wrong with the threads the holes are just bigger

There is no way shimano ever made any XTR cranks with a 1/2" pedal thread.
1/2" pedal thread is reserved for low end one piece cranks.

The only thing I can think is that some cranks have an insert that the pedal screws into that is mader of harder material than the crankarm. No idea if M952 cranks used this but if they did it sounds as though you are missing one.
