Brake Levers
SRAM Maven Bronze SRAM Maven Bronze features monstrous 18 and 19.5mm pistons driving 50% more power than Code. But best-in-class power means nothing unless you’re able to harness it. The Maven Bronze lever body houses Swinglink, which translates rider input for progressive power throughout the lever pull, maintaining SRAM’s signature ride feel. And because of a stiff 4-bolt caliper that sheds an incredible amount of heat, that feel remains consistent, so the last corner feels like the first corner. Maven Bronze features a Dark Polar Anodized finish, and tool-free Reach Adjust. - Brake Calipers: SRAM Maven Bronze
- Rotors: Shimano, BR-MT420, 4-piston caliper, hydraulic disc
- Headset: Specialized Angle-Adjustable Headset
