Complete System Weights
To get some total weights you'll need to add in the following:
- rotors - see here for some lightweight options ;
- rotor bolts - if you get some Avid 2012 HSX rotors they come with Ti rotor bolts;
- brake pads - perhaps some alu backed ultralight versions ;
- caliper mounting bolts;
- brake cable inner and outer weights;
- any adapters you may need for either running larger than 160 rotors or for converting ISO to post-mount.
A lot of the info in my Hygia SLP tuning article will also apply to weight savings on a mechanical BB7 setup.

Two different types
Avid make both road and mtb versions of the BB7. The difference is in the amount of cable pull that the caliper requires. The road version is for use with road levers that pull less cable than v-brake levers. If you have old school canti brake levers on your mtb you can use the road version of the BB7.
