What are the advantages/disadvantages of having these very wide looking teeth with flat tops on sprockets? Is it just supposed to wear more slowly?
If it's better to have these on a single speed, I'm wondering why, for example, my redline monocog has much more pointy looking teeth on both the chainring and cog than some of the aftermarket singlespeed cogs/chainrings I have seen pictures of on here.
Is there some disadvantage of them? Are they noisier?
