You could never be throwing a spanner in the works buddy, "simply adding more interesting & important information to the table
Any chance you can throw up a pic ?
Its sounds like it could be a Mavic from a different mech. Thing is with these stop plates Ned, after a good look at 1 all they do is grab the mech body and then locate onto the stop lip on the dropout. The critical dimension in my mind so far is the "thickness". I've got to get this spot on or the mech will over tighten OR slop, neither of which is acceptable.
Sure the other dimensions are important too, but not I believe to within a 1/1000th of an inch. The 2 upturned parts clasp the mech body via the indentations at the base of the pivot barrel. The other lip is of course the stop. Hopefully our good friend 1'ied Jim can send me an original 1 OR perhaps someone can upload a good close-up pic of the stop plate fitted to a mech/bike.
I have figured that if my own 801 will work, then the replicas will also do the job perfectly. Once I have 1 that is perfect, I'll go into copy mode
Thanks for the post Ned, later buddy, yours Laz.
