Just a recommendation re mechanical vs. hydraulic disc bakes. Disc brakes of any kind is a big improvement over "canties", side pulls or v-brakes. I choose mechanical disc brakes when I upgraded my Fisher because frankly for a futz like me there's less to go wrong, maintain or fix. I'm a big gal and have absolutely no trouble stopping with my mechanical disc brakes. I can do wheelies without a problem! Yes I agree hydraulic are best but mechanicals are good as well. And if a small gal, I would stay with V-brakes. Disc brakes add weight to the bike.
