I've got a pair of Mach 5 SX's that I was about to Ebay. Paint is a bit tatty, and I think the bottom out elastomer needs replacing, but other than that they seem to be working fine. 1 1/8" steerer.
Thanks Sam I've got a set with a similiar length aluminium steerer and I think that one is probably to short for what I have in mind would take them if 1" size or if anyone has a steerer/crown in 1"
