Thanks for this thread and replies!

I've had the same issues myself on both my road and CX bikes. I started in the second row in my first CX race, started fine and was in the top 10, and then dropped my chain within 3 minutes. Finished 20th. Boo.

So I was looking at the K-Edge because that's the one I'd heard of. Ridiculous pricing. The Token and N-Gear look much more reasonable.
