Fasst Company is out to kill vibration and hand fatigue with their pivoting Flexx MTB handlebars. Available in several variants, the bars use unique compression and rebound elastomers for a completely tuneable and smooth ride. All feature an effective five degrees of suspension movement, with optional clamping widths to accommodate standard and direct-mount stems.

Fasst Flexx MTB suspension elastomer handlebar for enduro, DH, and e-bike

Elastomer suspension systems for seatposts and stems are well-established, but using them in a handlebar is certainly not as wide-spread. Fasst Company gets it done with a 7075 aluminum center, carbon grips, and a dual-pivot design with replaceable elastomers.

There are four different models available of the Flexx bar. An Enduro/DH model has a 63 or 73mm wide center section for standard or direct-mount stems (with 800mm and 810mm widths, respectively). E-bike versions carry identical dimensions, but use heavier-duty elastomers to deal with the added weight and speed of pedal-assist bikes. All models come with soft, medium, and firm compression and rebound elastomers. A full spec list can be found below:

  • Rise: 25mm
  • Clamp Diameter: 31.8mm
  • Weight: 440 grams
  • Width: 800mm Enduro, 810mm DH
  • Upsweep: 5*
  • Back sweep: 8*
  • Center Tube Width Enduro: 63mm
  • Center Tube Width DH: 73mm
  • Materials: American Made UD carbon, 7075 Aluminum, Ti-6Al-4V
  • Effective suspension travel: 5*, length of bar dictates overall travel.
  • Elastomer included: Soft, medium, hard compression and rebound.
  • Patent#6,860,500

Fasst Flexx MTB bars are made in the USA and carry a 30-day money-back guarantee. All models are available now for a list price of $425.

  1. $425 for a handlebar???!!! And it’s not even custom or Ti. And it’s actually for MTB?
    This article is like an April Fool’s Day joke but in August.

  2. Suspension fork alternative using temperature sensitive elastomer springs to offer a centimeter of travel, flying the US flag with pride… it’s like it’s 1992 or 1993, but with 2019 prices.

  3. Also, looking at the language used on their website, it looks like English is not their first language, even though the product is supposedly made in the US. “Impacts” or “bumps” are called “abuse”.

  4. I was skeptical, and then I read the price, and then I had to re-read the price, and what happened next was that my skepticism transformed itself into cynical laughter. Who are these guys and who do they expect to willingly hand over $425 for an unknown-and-gimmicky handlebar? Seriously, what are these people thinking? Do they really believe that the bike market is made up of bikers that are easy-to-convince-with-loads-of-cash-burning-in-their-pocket-crowd-as-long-as-there-is-some-carbon-fibre.
    $425… really? Elastomers, really? Why not throw in an integrated “soft-ride” suspension stem as part of the solution. 🙂 Good luck. Cheers.

  5. How stiff do you have to run the suspension on your 200mm travel DH bike or your 170mm travel Enduro rig to need even more suspension in the handle bars!

  6. Flex bars have been around for awhile in the offroad motorcycle industry. Yes, the price for the mtb version is ridiculous like alot of cycling products.

  7. Didnt proflex make a stem before suspension forks were invented? I think this has to be the worst idea of the year, if not the decade?

    • So, what you are really saying is that it is not a new idea at all. Softride, ProFlex and others had the same flavors in a different pile of poo. While I do not at all understand adding the system to a bike with a susp-fork on it…would make a itsy bitsy tiny bit of sense on a commuter or what not (but, at a WalMart price a typical hipster on their way to the coffee shop might maybe be able to afford).

  8. An obvious place for this concept would be the gravel market. Make them with similar bends / drops / sweeps to the Salsa Cowchipper / Cowbell and in the 7075 AL version for $100 and you would have a winner.

  9. This is a play on the old flex stem from the late 80’s. I could see it being used in a head tube setup for a gravel road bike, but not on a MTB.

  10. The flex bar is from the Motocross world and they do work very well the price is a little high but if they make you comfortable on the bike you won’t care about the price

  11. I’ve ridden these bars. While I wouldn’t shell out MSRP for them (or even close), I will say I was impressed. I rode them on a 170mm travel bike for three rides then switched back to a 35mm carbon bar. The Flexx bars noticeably reduce arm pump and hand fatigue. You can only sorta feel the flex if you really pay attention.

    Worth $425? Not for me, but if you ride 10+ minute downhills regularly and have trouble with arms/hands they’d probably help a lot.

  12. I’ve used them for 5 months. They do reduce fatigue and smooth out smaller high frequency bumps. Haters can hate, just like they did on oval rings……. time will tell…….. but make up your own mind or follow the lemmings YMMV
