It took 15 mins both sides

Circlip needs to be removed from the bottom of the holding pin.

Then extract with fingers or a pair of pliers’, well you can if you grease the pins after you ride/wash, If not I guess that will be a brass drift and hammer then

Copper Slip the pin, insert and replace the circlip (top tip use a new circlip every time)

The Pivot Pegz come with a Elastic band round the spring LEAVE THAT ON WHEN FITTING AS IT HOLDS THE SPRING IN PLACE, SO YOU DON'T HAVE TOO

Up the road and back and it's feeling good

but time will tell.
Seems to be good quality, maintenance has gone up Because the pivot will need a grease

and it's possibly twice the weight of OME peg
As for the height its much the same as stock, I'm 6'4" and my problem is Bar position not feet which give me issue's. So ROX RISERS and ditch the aftermarket risers
