you guys ****ing scare the piss out of me every time you think you have a good idea.

save some money and do it correctly. it will save you money in the long run in both bike parts and human parts.

for the miche cog system you need to have the lockring on in order to keep the cog on the carrier. chain tension or lack there of will only help the cog come off of the carrier.

i have this system on two of my wheel sets. both are over 2 seasons old and have no play or excess wear on them compared to other cogs. one is going on its 3rd full season of daily commuting the other is on its second season of racing at the velodrome. with enough preventative maintenance and proper install this system will last as long as any regular cog.
