There aren’t too many flattop chain options. Honestly, I think SRAM is the only one (YBN makes one) with the pure flat top edition, which they developed for their 12-speed road groups. Yes, you can use the KMC X12 to replace a current flattop setup, but if you want the smooth look, you’ll have to buy a SRAM chain. However, it appears that KMC has a SRAM-compatible flattop design in the works, and it looks to be dropping soon.
KMC 12 Speed Flattop Chain – What is it?
We know that the new KMC 12-speed flattop will be an option for SRAM riders who might want an alternative to the SRAM chains.

Reusable Flattop Quick Link?
That was the first thing I asked (that would rule, right?) and was left with zero speculation. The quick link will be a single-use-only piece, much like the current SRAM Flattop offerings. However, the chains will come pre-waxed (like the newer KMC waxed models) and with an all-new KMC flattop quick link.


KMC is keeping this one pretty close to the chest. It’s uncertain if an “X12SL-FT” model would accompany the release (the chain in question looks more like a standard X12 model), and the same goes for pricing.

Availibility
Whether this is an upgrade or an adjacent option for SRAM riders, one thing is certain: it’s nice to have another option on the table. I’d be set and sold if we could only get this in GOLD.
Look for the KMC 12-speed Flattop Chains available midsummer at your local shop and online at KMCChain.us.
