Truvativ HammerSchmit (AM)
It’s not every day that you get to ride something as unique as the Truvativ HammerSchmidt. What Truvativ has designed, a planetary gear system, is impressive to say the least.
What HammerSchmidt does on the surface is replace a double ring setup with a single ring one that offers the same gear range, but there are many more benefits to it. Read more inside.
While the idea isn’t new to the transmission world, it is impressive to see the idea implemented in a crankset to effectively replace not only the double ring setup, but also acts as a bashguard and a chainguide all in one. Before we delve into the details of the ride here is a run down of the two versions available for after market purchasing.
HammerSchmidt will come in two flavors, an AM and a FR Version.
