I am trying to modify a pair of racing/training so as to be able to use standard removable spikes.
I can't figure out what the thread size is and neither can my excellent hardware store. It is neither M6 or 1/4" 28.
I have tried Google to no avail.
I am familiar with LaSportiva's A.T. Grip Hobnail Kit, but they use short brass spikes that are not adequate for the packed snow with dirt underneath challenge that I have.
thanks
