Designed for both professional mechanics and dedicated home enthusiasts, this essential general tool transforms one of the most challenging tasks—routing cables, hoses, and wires through internal frames—into a quick and effortless process. Say goodbye to guesswork, dropped lines, and potential frame damage, and embrace a smarter, more efficient way to build and maintain your bike.

At the heart of this innovative system is a powerful magnetic tool designed to masterfully assist with internal routing. The kit is expertly engineered to be compatible with a wide array of cables, housings/hoses, and electronic wires, making it a versatile addition to any toolbox. The core function involves a powerful lead magnet that expertly guides the included adapters through the most complex internal frame channels. This magnetic guidance system significantly reduces installation time and ensures a clean, rattle-free setup every time. To safeguard your investment, the guiding tip is covered in a soft, durable fabric, which protects your frame´s delicate paint and carbon finish from scratches during operation.

Beyond its primary routing function, the BIRZMAN Internal Cable Routing Kit features an intelligently integrated awl. This clever addition helps restore freshly cut housing ends, ensuring a clean and perfect surface for easier attachment with the corresponding adapter. It also serves to clear any obstructions or liner material, making a clear path for seamless cable insertion. The kit´s versatility is further enhanced by a flexible magnetic extension, designed to navigate tight bends and hard-to-reach areas within the frame. Accompanied by four individual adapters and a lead wire, you have everything needed to tackle virtually any routing job with confidence and precision.
