Renthal

Duo Stem

Appropriately, given the UK-based company's motocross background, the Renthal Duo Stem demonstrates Renthal's different approach to the sport of mountain biking and its associated parts. The Duo's incredibly low weight is the result of its unique construction. The stem is split in two halves, lengthwise, which grants the engineers — and more specifically, their CNC machines — access to the stem's interior, allowing them to precisely machine away far more excess material than is possible when stems are forged from single pieces of alloy, as most are. Despite their low weight, the Duo's able to maintain insane strength, thanks to intelligent engineering and the ultra-tough 6082-series aluminum from which it's made.
