A different approach for a better 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.

Renthal Stem

  • Familiarity: I've used it several times

I am from a moto back ground and Renthal has always made quality parts. This part adds a little bling and control to my bike!

Matches nicely to Renthal Bars

  • Familiarity: I've used it several times

Currently installed with a Renthal Carbon bar and I don't have the squeeks and noises peopel complain about. It is a bit tricky to install at first but once you figure out a way its pretty simple. I tighten the bolts on the bottom piece on the steerer tube first, then the handle bar, then the top part touching the steerer tube. Very sturdy and stiff. Light as well. No complaints.

Best companion to the Renthal FatBar

  • Familiarity: I've put it through the wringer

To start off my bike came with this stem from the factory and overall I have disassembled it and put some miles on it since buying. I hear a lot of reviews on different sites and forums saying that this stem creaks a lot. I have not had 1 creak or noise come from this stem. It's easy to install and maintain, and is hassle free as far as I'm concerned. I have the 50mm and it makes my cockpit on my T275C PERFECT! Get you one!
