I read some traffic on other bike boards where people were debating if Sixity brake pads were any good.
You may have seen these for cheap on Ebay and wondered if they were OK. I use them, and they work fine.
I bought a complete set of ceramic sixity pads for about $50. They work great, I think they feel better than the stock pads did. I also had a set of the sixity sintered pads on an old Helix, those were fine too.
