Is the conventional wisdom that brake cable tension should be as high as possible without causing excessive friction still the best approach, or are there situations where slightly looser cables might actually provide better overall braking performance, particularly on technical descents where rapid modulation is key? Should we be aiming for a specific tension spec, or is it more about finding the sweet spot that balances power with feel and control? Are modern brake systems, with their improved aerodynamic and ergonomic designs, more sensitive to cable tension than their predecessors, and if so, how should this inform our setup decisions?
