Our most popular stem by far. It's cold-forged aluminum in the traditional "7" shape, with a 225mm quill so you can jack up the bars high.
The 25.4 fits our Albatross, Choco, and Bosco bars, as well as most city and mountain bars (any with a 25.4mm center section).
The 26.0 fits our drop bars as well as most drop bars from the past.
Note that many mountain and road bars have gotten super burly and require 31.8mm stems. The Tallux doesn't fit them.
Note also that NITTO (and therefore we) don't consider the Tallux for off-road riding. It is a strong stem, but once you say, "good for off-road, too," you're opening the doors to abusive-showoff-stunt riding, and this is not for that.
For off-road riding, get a DirtDrop. Happy Trails!
