Fasst Company MTB

Just installed Flexx bars on my 2022 Levo, have to say they made a huge difference. Much less fatigue after 3 rides with them.

This is probably my 10th set of Flexx Bars. I have some bad wrists and my time on a mountain bike was limited by how long I could hang on and ride safely on gravity trails. Before my 1st Flexx bars, it was a MAX of 4 hours a day and I had to take off a week at least. Since riding with my Flexx bars, I'm a solid 6 hours, and there is no limit to how many days in a row I can ride because of my wrists. Absolutely a game changer for me.

Aside from having multiple bikes myself, the ones I borrow to friends/family (that they eventually buy) all go with the Flexx bars because they won't go back to traditional bars after spending a day or two riding with these. I feel like I missed 10 years of good riding because I didn't know these bars existed.

My advice -- get a set, DO NOT WAIT. Once you do, you will be hooked. Grip strength and wrist pain, hand numbness --- all improved with these bars drastically for me.

100% recommend 100% of the time in 100% of situations. Even without bad wrists you will find these to be the most comfortable bars you can have if you like gravity and have weight on your bars.

Thank you FASST!!

These are a excellent upgrade to my trek rail, I’m 60 years old and have started to have wrist and hand problems, these have taken out the chop to the hands, high quality and great product! Thanks Jason!

Great handlebar well engineered with a perfect rise and sweep

If you’re reading this you’re probably considering buying one of these handle bars. I have arthritis and carpal tunnel in both hands and this handle bar provides a lot of relief. After multiple rides I decided to swap out the stock elastomer and go for the softer yellow elastomer which provided a little more flex. At no time have I ever felt that the bar flexed too much thus causing a lack of performance. I have been very pleased with this purchase and highly recommend this product.

I wish these bars weren't as effective as it would make it easier to go back to normal bars on my other bikes.

I love the comfort these provide in the bump axis while still being VERY stiff in the steering axis

I first started riding these on my 170mm travel enduro bike and I think it's most effective on higher frequency chatter (like braking bumps). It allowed me to run a firmer, more supportive setup without compromising comfort.

I also tried it on my shorter travel 140mm trail bike and I found the improvement to be possibly even more important. It extended the range of capability of the bike as speeds increase since you just don't get as beaten up. Again, I could run a firmer suspension on my fork without reducing comfort.

Downsides... You need to service your handlebar. And it is also a good idea to have some elastomers spare as these do degrade over time. Just a little TLC now and then.

Been using it for five years! This handle provides comfort, stability and after-sales service. I am very satisfied! Thank you for creating a great product!

I have Fasst Flex bars on my Levo's and my KTM. Big fan!

I have Fasstflex bars on all my bikes now. Four mtb and two dirt bikes. Ridiculous and unnecessary right?
No, I have these because they are that beneficial. I receive nothing for this review. I am just a firm believer in the bars. They absorb quite a bit of the braking bumps and small chatter you experience out there in the dirt and when hitting G-outs or harder impacts they do not flex too much to make it awkward. They also come with three densities of rubber compounds to adjust to any specific rider’s needs.
I’m an older guy so it really helps me with fatigue and numbness in my hands. These bars allow me to continue enjoying myself out there and I would recommend to anyone

I've been running carbon bars for years for its famed vibration mitigation, but I still get hand numbness and fatigue in DH runs. I've even tried OneUp bars: but it still didn't help much. After enough research, I discovered Fasst Flex Bars and have them a shot.
It was a world of difference in vibration mitigation compared to carbon. The elastomers do a way better job at absorbing vibration of both small and high speed trail chatter. For the first time, I don't get hand numbness and fatigue anymore.
The bars come with different elastomers with varying degrees of softness in how much flex you need. I've kept it at the stock elastomer, as it's recommended for more aggressive riders: stiff, but enough flex for dampening. I ordered the 12° backsweep, and that makes a world of difference in how your hand sits comfortably in the bars.
Setup is simple, but you must run the bars direction of flex must be in line with your fork. I had typically ran my bar rolled forward to increase reach and rise, so following these directions shortened both, especially since I ordered the 12° backsweep. I compensated by installing a Renthal Apex 60mm with a 6° rise, and that helped with the reach (but I wish the rise was a bit higher). The bars come in 800mm, but I cut them down to 760mm: cutting them didn't affect my leverage on the bars during flex so I still kept the stock elastomer.
Overall, it's the best bar I've ever had. Though a bit pricy, it's worth every penny for the best vibration mitigation bar that eliminates hand fatigue. Heavier than most bars, but in an ebike it doesn't matter.
(My only wish is if they make a 40mm rise, I'd gladly buy it)

These bars are amazing, no other way to say it. I've been running them for a season and a half on my Yeti 160e, a big heavy ebike. Shoulder and wrist pain went away within days, and the ability to tune the bars to your riding style is excellent. If you ride aggressively, sooner or later your body lets you know it's time for a break. These bars extend your season and are burly enough to handle any terrain.

I have tried the carbon bars such as the Oneup that are supposed to absorb vibrations and reduce arm/hand fatigue and I must say that there no comparison in the damping you get with the Flexx handlebar compared to standard carbon bars. The Flexx bar drastically reduces the effect of brake bumps and allow me to loop the chair non-stop for hours.

I quickly got used to the flex in the bar, which does not impair the ride quality in any way. The only drawback I can see is the weight of the bar itself ~600g.

I had a cosmetic issue with a bar and I can attest that the FASST company customer service is simply the best one I have ever encountered. They were super responsive and solve my issue in no time. I see lots of company that advertise themselves as having no BS warranties... until you have a problem. The team at FASST truly care about their customer service.

Just get one, it works.

Huge kudos to Jason and the team for taking care of my Fasst mtb handle bar for service. They stand by there commitment to their product.

I have been riding mountain bike for sometime and that took a toll on my forearms. Unfortunately I injured my forearm recently and had chronic tendonitis. Which is aggravated by riding mtb. I have to stop riding for several months despite of therapy up until i found and tried the Fasst Flexx mtb bars. It is amazing how it works and tremendously helped my forearm. Still with some soreness after riding but no excruciating pain days after. Now i can ride longer and continue to enjoy my passion. Thank you
