Hi all
I have a pair of old rs7’s with a triple ring 5 bolt spider but want to put a narrow wide ring on it.. (old Raleigh conversion)
Question is what is the bolt diameter? Any answers would be grand 😀 thanks all x
Best just to measure it.
It’s probaly 110mm pcd but middle burn used to make spiders to suit anything and every thing
Must be getting old maybe 94mm
Contact hadge who contributes occasionally - paul hadgett of BETD who bought Middleburn; you could call him at work.
Just measure between 2 adjacent bolt holes and use a conversion table.
They had Middleburn rings on it when I got given them?? What a nice friend I have 😀
Yea they are from the 90’s I also have a pair of the x type’s as well (love the look of Middleburn crAnks on skinny tubes!) and the spiders do not look so discimelir?
When measuring the bcd do you measure centre to centre to the next closest bolt?
Thanks again
