NOTHING worse than having arm pump while out on a really long dirt bike ride!

On some multi-day riding trips on the mountains, I would have given my kidney for a set of Flexx Fasst handlebars, just to alleviate the terrible arm pump. 

I try to ride a bunch but sometimes it’s just not enough for those really long dirt bike trips where my arms do not have time to heal and I just am trying to hang on. 

Flexx Fasst Handlebars help with arm pump, shoulder, and wrist impact.

They’re billed as the ultimate performance upgrade for your dirt bike or mountain bike, and they’re priced accordingly. 

Fast Flexx handlebars put a pair of shock-absorbing elastomers between your hands and the contact point bars on your bike to provide a completely unique handling experience, so let’s take a look at the pros and cons of this unique product and see why they’re considered the best dirt bike handlebars. 

The differences come from the variation in height of each elastomer, which works in conjunction with the varying durometers. Each combination gives you an upsweep of 5 degrees, but they take up the same amount of space within the pivot area. All of which means you can match the level of stiffness to the terrain-it's an advantage that's hard to match, and it's one of the biggest reasons why you should choose Fasst Flexx handlebars.

  • Tunability. There are four sets of compression and rebound elastomers that come with each bar, which means you can set your bike up for soft, medium, hard, and extra hard. 
  • Horizontally, the bars allow you to pinpoint your steering line more precisely, and vertically, they smooth out the normal pull you’d feel from roots and rocks. This allows you to ride harder in rough terrain and even use roots for landings, giving you a faster ride with extra control.
  • Braking hard is easier as well. The sharp vibrations you’d normally feel when going over rough terrain are muted, and once again the result is more control. That means you can go longer without fatigue, and longer race runs are easier, too.
  • Less Arm pump, shoulder and wrist impact.
  • No more big hits. The hard elastomers definitely take the edge of the big hits and smooth out the roughness of the trail, not to mention lowering the aforementioned fatigue factor that comes with longer rides.
  • There’s a 30-day “Ride it, Believe it” money-back guarantee that gives you 30 days to try the product and justify the cost of the product. If you’re in love with the product but not the price, there’s also a more affordable aluminum version that will allow you to save some bucks.

  • Price is the most obvious drawback of the Fasst Flexx. At around $400, it’s a tough upgrade for most riders to justify, at least until they experience the benefits they provide.
  • It’s easy to forget that the bars are a moving part, and over time the torque of the elastomer bolt can work loose. You won’t lose the bolt because the slippage occurs in a downward direction and it can’t fall out, but you may want to use some Loctite 243 to make sure it stays in place.
  • It takes some time to get used to riding with the Fasst Flexx. Most riders need to experience the “bendiness” of the bars to get a handle on how to use them, as they alter many of the perceptions that come with normal riding in rough terrain.
