The Twenty6 F1.2 Stem doesn't look like any other stem on the market. The F1.2's sexy looks aren't all for show, however. The innovative clamp design is ultra-strong and knee-friendly. Every gram of unnecessary aluminum has been removed to keep the F1.2's weight as feathery as possible while maintaining the strength and durability you expect. Rise is plus or minus six millimeters, depending on the stem's orientation, so you can just flip it to dial your geometry.

Twenty6 products has only been around for a handful of years, but it has already revolutionized the industry. Each of its machined aluminum products is designed from the ground up in Bozeman, Montana to look and work better than anything that that the bike mega-conglomerates are churning out. If you're looking to get away from the cookie-cutter look and feel of the industry giants, you may want to take a look at Twenty6.

The Twenty6 Products F1.2 Stem is available in 50mm. It comes in your choice of four different colors–Black, Orange, Red, or Green.

Sure, the F1.2 stem looks pretty but it's also incredibly strong, and well made. I've been a fan of Twenty6 products for a long time, their stuff is unique and the craftsmanship is apparent with this stem. My Pivot Mach 6 came with a 70mm stem from the factory, and going to the 50mm put me a better position for all mountain riding. I also dig that you can switch it from flat to 6 degrees of rise.

Put this stem on my nomad a few months ago and it hasn't disappointing, I had a 35mm stem on before changing to 50mm and love the extra room in my cockpit and added durability of this stem. To sum it up it' light weight and looks amazing.
