KCNC lightweight cassette with 11-38 cogs

In addition to the trick titanium DLC headset and spiderweb chainrings found on the Fair Wheel Bikes builds (road and mtb), FWB had a number of other new goodies from KCNC on hand.

Above, perhaps just for shock value, is an 11-38 mountain bike cassette. They’re working on an extended derailleur cage and/or mount to give it the clearance it needs to work with such a large cog. The other is an 11-23 for road. Super light, starts around $370. Make the jump for weights and more…

For comparison, a SRAM Red 11-23 is 155g (claimed) and 11-26 is 166g. XX is 185g (11-32) and 208 (11-36).

Dura-Ace is 163g for 11-23, XTR is 255g.

KCNC lightweight springless road pedals

New KCNC road pedals are 200g per pair with cleats, approximately 165g on their own. No spring tension, it simply uses a tab to push a bar into the back of the cleat. It can’t come out from upward force, but slides/rotates out like normal to release. Removing all the spring mech saves a ton of weight. Still prototype, no pricing.

KCNC DLC diamond like coating like shift and brake cables

Lastly, and with virtually no info, are their DLC-like coated cables. Yes, if you spell out the acronym, it’s a bit weird: Diamond Like Coating Like. DLC is a super hard surface treatment that Rockshox has been playing with on their fork sliders for some time at the blackbox level. Problem is, it’s not actually flexible and tends to chip and crack too easily, especially considering it’s monstrously expensive. So, we don’t actually know what this coating is, but it feels pretty slick.


  1. This coating is use in the knife/multi-tool industry a lot (guns also). Dishwashers, stove and some other appliances have it to. All that really nice stainless steel you see on them, that coating is what keeps them looking so nice over time.
    It is very expensive the only way they can reduce the cost is by volume (number of coated parts). I worked for a Mutl-Tool manufacture designing products and a few of the parts I designed had this coating some for show others for durability/performance. We work for 2 years to try and reduce this cost and that was the only way we could justify it.

  2. A 38 tooth cassette is not just for “shock value”. Super low gearing is nice and is a necessity for heavier 29ers. Hopefully shimano will make a 38t cassette for the working man.

  3. You don’t need a special derailleur to run 38T cogs. I ran a 12-38 cassette several years ago with an SLX derailleur with no modifications and no issues shifting.

  4. I’ve seen a 38T titanium cog installed on someone’s bike at JensonUSA about a month ago. It was so flexy that you could bend it a great deal easily, by hand.

  5. “is a necessity for heavier 29ers”

    perhaps you need to rethink how much ‘advantage’ being different on that 29er is really giving you 😉
