Vision TriMax Carbon Road StemDelivering a strong and secure connection between your handlebar and your fork's steerer tube, this high-quality stem is ideal for road cycling. Its 3D forged and CNC-machined aluminium construction means that any excess material has been shaved off to keep weight to a minimum, while still offering maximum durability. Vision has also equipped this model with a unidirectional (UD) carbon finish, which uses a carbon skin that's applied through a CSI process for reinforcing the strength of the aluminium centre and ensuring an exceptionally low weight from the carbon. Coming complete with a four-bolt alloy faceplate that's fine-blasted and anodised, this road stem provides a dependable interface for holding your ride together, mile after mile.Features: Material: 3D forged and CNC machined Aluminium Finish: Unidirectional (UD) Carbon (UD Carbon skin applied through CSI process) Faceplate: Fine blasted anodised Alloy Hardware: Chromoly (CrMo) Steel Use: Road Handlebar Clamp Diameter: 31.8mm Steerer: 1 1/8" Fork Clamp Stack Height: 35mm Angle: -6 degrees Weight: 157g (100mm option)Manufacturer's Part Number: 670-0338016030 80mm 670-0338017030 90mm 670-0338018030 100mm 670-0338019030 110mm 670-0338020030 120mm 670-0338021030 130mmBuy Vision Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
