does anyone knows what size mount kits do i need for the monarch plus?
my frame is 2014 giant trance 27.5.
i dont know how to measure the bolt diameter(m6 or m8), and if its 12.7 or 12mm eyelet and also the length.
thank you for the info...Your should be 21.85 mm wide are are standard 13mm (1/2 in.) ID eyelet.
Don't know if they are M6 of M8. If you have the old ones, just measure the ID (or the OD of the mounting hardware.
