getting a new cog lockring etc. saw the miche cogs and was wondering if the cog holder system is any good.

Yes, they are good. If you search you will find several threads and plenty of people who like them.

250lbs, known for shearing pedals, bending chainrings and breaking axels and it is holding up very well so far... I really dig it... so much easier to change cog when I need to...

I like the system a lot for the track. I don't really like their Lockrings though, they seem a little bit junky to me.

+1, Miche lockrings are ABSOLUTE garbage. They're not cleanly made and shouldn't be used. If you do end up getting a miche lock ring, do me a favor and run your finger along the threads.... then go get a bandaid from all the burs....then go get a tetanus shot

will do. avoid miche lockring at all costs

miche lockrings are italian threaded.

you still need tools and grease so i dont see a huge advantage.

Miche lockring's threads are a tad thicker/wider than English/ISO threads.

Actually it's the thread diameter and 1 tad = 0.734mm or 0.0289". Since the thread pitch is 24 tpi on both of the sizes, it's easy to mistakingly use a Miche or Campy or Phil lockring on a hub meant for the smaller (1.29x24) hub standard, and strip the threads when tightening.

Here's a typical installation >>> https://www.worldclasscycles.com/mich...ier_on_hub.htm

Note the use of a Dura Ace lockring. This is how mine is set up.

dummies,

take note.
