This popular Millennium stem is constructed from Ergal 7075 T6 with a sand blasted anodized finish and silver coloured cap. This 31.8 mm stem is for use with oversized handlebars but comes with a shim so that standard 1" or oversized 1 1/8th" steerers can utilise this 80 degree angle stem. The Millennium 4Ever stem has the extra safety of a 4 bolt front plate system.
