not for the first time i have waited weeks for stuff stuck in post,
I swaped over GR brakes for GPX not too hard a job, any how go the scales out again
was surprised to see them come in at 25klg thats with new discs and pads...........then did the same with the GR brakes with worn discs and pads they came in at 18.5klgs, 6.5 lighter so with the aircon gone(17klgs) and bigger brakes still 11.5klgs in two days not bad for a slim guy
