Features One of the OG members of the Neo Chain family. The Eurostile Nuvo now features an ultra-strong cut-resistant sleeve on top of the popular 5mm steel chain. The 100cm (39.37inch) length provides an adequate user experience for both transporting and locking to fixed objects. Nuvo Chain utilizes UHMWPE (Ultra-high molecular weight polyethylene), one of the most durable and strongest fibers. Inside the fiber, there is also a 5mm steel chain, which makes the Nuvo Chain more cut-resistant compared to a conventional nylon-based sleeve.
