The Boss v2 Stem updates Aaron Ross' signature Odyssey Stem keeping that classic top-load, 6-bolt design. Fully CNC machined from 6061-T6 aluminium it's a solid stem that's strong and durable, with side cuts and cut outs reducing the weight. Along with the other newer Odyssey stems the bolt heads have been upgraded to a larger size as well as unique surface contouring for superior handlebar grip. ###section### Product Specs TYPE: Top Load REACH: 52mm RISE: 35mm CLAMPING DIAMETER: 22.2mm WEIGHT: 308.4g (10.88oz) Colour: Black
