They were made before the HMX9’s came out but the caliper will work with the HMX system.
Hey Asphalt Jesus,
If you go on ebay.com right now you can find a pair of bushings and a pivot tube for sale. Its been for sale for a long while. The guy wants a bit too much if you ask me, but if you have some $$ its definatly worth considering. I bought a extra pair of bushings on ebay a few years ago from a guy that bought several pairs directly from the original manufactuer. I thought I might need them eventuly, but I’m continualy amased that I still don’t need them yet. 4 years ago I cracked a carbon Homegrown and sold on ebay a pair of bushings, pivot, and a rear triangle on ebay. Happy hunting and good luck, and God bless.
