Both sides of the spacer have 6 x 70mm diameter M5 threaded holes and 6 x 70mm 5mm pass-through holes, so you can either pass bolts through or bolt to the spacer.
We have made the spacer light at 155 grams. It has a tapered center to add strength.
Supplied with 6 x M5 bolts
Please note, Following customer feedbackI wanted to point out that threaded and non-threaded holes are offset on each side - So a threaded hole on the top is non-threaded on the bottom.
