Miche cogs are not cheap stamped cogs. I have been using mine for years with no problems.

Once you install the carrier you can swap cogs without unthreading them, so you stand less chance of f'ing up your threads. If you change gears often, its a great system.

Plus, the whole system is way cheaper in the long run. The splined Miche cogs are cheaper than normal threaded cogs. Unlike threaded cogs, Miche cogs are reversible, meaning that once you wear out the teeth you flip it over on the carrier and, viola, new cog.


If you have a 47 tooth ring and normal 700c wheels with 23-25 mm tires, I question the need to go larger than an 18t cog. Gear it too low and you will lose more speed going downhill than you will gain going up.
