Designed with a cable-operated mechanical disc brake system, it allows you to upgrade to disc brakes without the complexity of hydraulic fluids, making maintenance simpler and more accessible. Its flat mount design fits 140 mm frames, and with an adapter, it can accommodate 160 mm rotors, giving you flexibility for different setups.\u003c\/p\u003e\n\n\u003cp\u003eCrafted from a forged one-piece alloy, this caliper is lightweight yet rigid, ensuring reliable stopping power while keeping weight low. The increased pad-to-rotor clearance minimizes rotor drag, while the adjustable pad clearance and shim-less mounting bracket allow for quick, easy installation and fine-tuning. Compatible with both Centre-Lock and 6-bolt rotors, it is recommended for use with Ice Tech rotors to optimize heat dissipation and braking performance.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eUpgrading to disc brakes on road or cyclocross bikes without hydraulic fluid systems\u003c\/li\u003e\n  \u003cli\u003eRear wheel use on 140 mm flat mount frames, adaptable to 160 mm rotors\u003c\/li\u003e\n  \u003cli\u003eQuick installation and easy adjustment with shim-less mounting and adjustable pad clearance\u003c\/li\u003e\n  \u003cli\u003eEnhanced braking control with lightweight, rigid forged alloy design\u003c\/li\u003e\n  \u003cli\u003eImproved heat dissipation when paired with Ice Tech rotors for consistent braking\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFront wheel braking applications without appropriate adapters\u003c\/li\u003e\n  \u003cli\u003eUse on frames that do not support flat mount disc brakes\u003c\/li\u003e\n  \u003cli\u003eCompatibility with brake levers not designed for mechanical disc brakes\u003c\/li\u003e\n  \u003cli\u003eRiders seeking hydraulic brake systems for maximum modulation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs this caliper compatible with all road bike brake levers?\u003c\/strong\u003e\u003cbr\u003eIt works with existing compatible road brake levers or STIs designed for mechanical disc brakes, but not with hydraulic brake levers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this caliper on the front wheel?\u003c\/strong\u003e\u003cbr\u003eThis model is designed for rear wheel use on 140 mm flat mount frames.
