Advice on speccing mechanical brakes for my tandem, please. Contenders are BB7 Mountain and Spykes.
- BB7 cons: single pad travel makes it harder to get rid of disc rub, old plastic body could melt
- BB7 pros: super easy to adjust cable tightness (pad travel), new metal body doesn't melt
- Spyke cons: adjustment screw comes lose, risking brake fade or kaputt
- Spyke pros: dual pad travel, more modern (and theoretically evolved) concept
I don't know how braking power compares between the two. From what I read around, it's compatible. The Spykes seem to be a better option (more recent, more expensive, dual pivot), but the adjustment screw issue makes it tough to trust.

Am I worrying for nothing? Alternatively, could I install an inline barrel on the cable itself, and use that to adjust pad travel? I could then loctite the shit out of the adjustment screw and never touch it again.

Don't do this anyway, spyres and spykes have a barrel adjuster on the brake, but it's just to remove cable slack, they've got individual pad adjusters, like the bb7s, and like the bb7s the actuation arm should return fully and pad wear should be compensated for with the pad adjusters.
