If you get a good deal of a new or used bike that comes with hydraulic brakes, or if you get luck and find an ultra-cheap set on an internet special, all the better. They do have a nicer feel.

However, for rim to disk brake conversion I don't think it’s worth it for someone to pay the extra $ for it and go to the trouble of removing the old levers and installing new ones. People talk about the BB-7 b/c it's GOOD.

When people talk about the advantages of hydros, it bugs me that they don’t address the maintenance issues--what if you tear a line, or get an air bubble...
