- Lightweight, durable construction: hollow aluminum-alloy body gives you a noticeably lighter brake lever without sacrificing strength or stiffness—improves bike responsiveness while remaining robust for everyday use. - Standard 2 mm compatibility: designed for a 2 mm cable/hose diameter to fit the majority of bicycle brake systems. Suitable for both casual riders and more ambitious cyclists who need a reliable replacement or upgrade. - Adjustable feel and performance: quickly fine-tune spring travel and cable tension to match your personal preference. Adjustments help restore crisp lever action and improve handling on varied terrain. - Clear, matching aesthetics: available in Black, Red, Gold, Silver and Purple so you can match or accent your bike’s look while maintaining dependable braking performance. Key benefits — why you need these levers - Better control: lighter levers reduce rotating mass at the bars and, together with adjustable travel, let you dial in a firmer, more predictable bite. - Versatile upgrade or replacement: the standard 2 mm fit makes these levers a practical swap for many bicycle types without changing your existing cables or fittings. - Long-term value: durable aluminum alloy construction resists wear and keeps performance consistent over time. Practical use scenarios 1) Daily commuter: swap worn stock levers for lighter, adjustable levers to regain a crisp braking feel and tailor the lever reach for frequent stop-and-go riding. 2) Weekend sport rides: fine-tune spring travel and cable tension before longer rides to improve handling and reduce fatigue from imprecise lever feel. 3) Workshop or quick repair: keep a set on hand as a compatible, color-matched replacement for most bicycles during routine maintenance or fast fixes.
