Brakes
Four-piston brakes and the rotors to match, because stopping power is what makes steep terrain feel optional rather than mandatory.
Lewis LHT Ultimate and LHP-S4 sets bring titanium and ceramic pistons with triple adjustment. SRAM DB8 Stealth delivers mineral-oil power at a sane price. Pair either with HS2 rotors in 180mm or 200mm for heat management on long descents.
