Singlespeed & Fixed Gear - miche quick change sprockets...

has anybody tried these? i am making the leap to 1/8th" over the holiday, and while i was deciding what kind of cog to get, i heard about these things. i dont really like buying into systems, but just curious.

I've heard that play starts developing between cog + carrier once you've used it a while...

I've heard the same about the play, but it doesn't seem to be as bad as some people make it out to be. Like not noticable if the chain isn't perfectly tight.
I'd say only do it if you were planning to change cogs A LOT. like once a day. The fewer moving parts on the bike the better.

"It really filled the space between the dropouts on my frame!"

I use it because the system came with my rear hub. It's worked fine so far, but I wouldn't have done it if I'd bought the cog separately. Great for the track if you change cogs for a lot, but just an extra point of wear if you don't.

just use a flip flop hub. dont waste money on some gizmo.

Ive riden about 1000 miles on mine so far and Ive felt no play develop at all.
It sure beats using a chainwhip. Id recommend them for anyone who wants
to change cog sizes with any kind of frequency.

I have had no trouble with my system and have been riding daily for about six months on it. If you don't properly tighten the carrier and the lockring on top of the cog then play will develop. Other wise it is solid and easy to switch your gear.

If I understand the system correctly, if it were to develop play, you could still just replace the cog with a regular type anyway. yes?

You are correct, I just did that actually.

I'm not a fan. My lockring kept coming loose, causing my splined cog to push against it and potentially stip the threads. I kept tightening and re-tightening until I finally just bought a real cog.

I'm not sure I'd go the extra distance to use this on a normal hub, but I like the concept a lot. Notching a hub so that cogs slide on and off seems like so much less trouble, while being incredibly safer. No chainwhips, locktite, or stripped threads at inconvenient moments... That's why they now use it for cassettes on roadies and MTBs... I'm not sure about the rounded shape of these notches, that looks like it might generate wear over time when subjected to the stresses of fixed riding, but it does seem like it's worth looking at.
