How did they not call this the Sweet 16 (too obvious)? The Wolf Tooth Components 16T Cog is a great idea — it smoothes the transition between the 13T cog and the 19T cog on a standard cassette when you’ve installed a Wolf Tooth Giant Cog. It makes a lot of sense and your bike will shift much better, but Wolf Tooth’s product-naming team should probably re-evaluate their positions.
