Hayes HFX-Mag XC - Carbon, Front $35 + shipping OBO
I never built these up on a uni. I bought these for $80, used on display bikes, so have some cosmetic wear, but other than that they function perfectly. Here are some specs:
Anti-rotation reach adjustment bushing
2-piece master cylinder design for easy removal
Sintered metallic all-weather pad compound
Lightweight carbon fiber lever
Lightweight set of titanium bolts
2xTwenty6 Pink Brake lever to replace the carbon lever if you’d prefer.
The cable length is about 34.5" and the following pictures show the brake pad wear. These weren’t used at all. They were only installed onto display bikes, so the pads look brand new to me. Let me know if you need any other pictures!
