You know that “most technologically advanced” anti-chainsuck device that was revealed back in September and that’s coming stock on the new 2011 Tomac Supermatic?

We just got word from Joe at K-Edge that they’re ramping up production now and it’ll be available for sale on their website on February 15. They’re also working on getting distributors on board. Mark your calendars, get your BB tool ready and clean that drivetrain…and tell your sweetie you’ll accept a slightly late Valentine’s day gift. It does come in red, after all (and possibly blue, black and gold if they follow suit on their existing chainkeeper collection).

UPDATE: Price will be about $50 USD, and colors at launch will be red and black.


  1. Ha, the first thing everybody does on a new bike is take the plastic dork disc off the rear wheel, but now I’m ready to shell out money for fundamentally the same thing on the front.

  2. a spoke protector, aka pie plate, aka “dork disc” doesn’t prevent the chain from jamming, it only protects the spokes in the event that it does. Anti-chainsuck guards, in my experience, are only useful if your chain and/or chainrings are worn/damaged. I’ve never had a chain jam up on me with a new set-up, regardless of the conditions (in the PNW).

  3. @ Gillis I’ve seen it happen a number of times. Someone shifts at the wrong point while barreling down a hill, etc. It may not happen very often, but if you have carbon chain stays you better hope that you have some type of guard in place!

    @ Nick Yes, this is an issue that is currently not being addressed by manufacturers very well. I personally would run the MRP XCG on every bike I own, due to the fact that it provides bash protection for a triple, and an inner plate that makes it impossible for the chain to drop. Yet, on my new bikes with bb95, bb86, bb30 etc, there is no way to mount it under the bottom bracket lip. Simple fix though, manufacturers just need to include ISCG tabs on more frames, but it seems they are unwilling to do so for now. Sure, not everyone would utilize them, but it would be really nice for those who would.

  4. @zach: I’ve had it happen as well, but only with worn out chainrings and/or chain. It’s typically on an uphill (or possibly flat ground) when the chain is under load and won’t let go of the ring, shifting or not (usually mud and grit is involved as well). And I think you meant carbon CHAIN stays, not SEAT stays. I hope to never have either though. Ti for life.

  5. Any idea when/where i can get hold of one.

    A google search throws up nothing much other than this article 🙁

What do you think?
