Which Elastomer should I run?

Tunable to your preferences through our compression and rebound elastomers you control how soft or stiff the bar is. What’s remarkable about Flexx Handlebars is what you don’t notice. You should not notice, or notice very little, depending on your preferences, your Flexx Handlebars moving.  

Your Flexx Handlebar will come with yellow compression and rebound elastomers installed which is a good baseline for most riders. In the package are red and orange compression and rebound elastomers. The reds are soft, the yellow are medium, and the orange are stiff. Riders that weight less than 150lbs. or that are riding smoother trails or gravel grinding prefer the red compression elastomer with either a red or yellow rebound elastomer. Yellow rebound elastomers will provide a more traditional, solid feel. The orange elastomers are stiff, mostly reserved for aggressive down hill riders.


Some riders prefer a stiffer rebound elastomer than compression, this perfectly acceptable, and aids in the fine tuning of the bar to your needs.  

We are continuously working on different elastomer set ups, reach out to us if one of the above set ups are not working for you and we'll do our best to get you one that does. 

Please call or email us if you have any questions or need any help, we love to work with our riders! 

How to change elastomers

Tools required: T20 torx, 4mm allen

It is imperative to apply blue loc-tite to both the nut and bolt when reinstalling. 

The nut requires a 4mm allen, while your bolt uses the T20.  Loosen the the nut from the bolt. It may be easier to loosen the nut if you apply downward pressure on the handle with your forearm like in the picture. 

By taking some of the load off of the nut/bolt it is easier to unthread.  Notice when removing your elastomers how they sit in your FlexxMTB. It is important to install them with small side into the handle and the round side against the center section.  Orientate the elastomer so the bolt hole does not protrude from the handle or center section. It's important for the bolt and nut to have interference from the elastomer.  

With the elastomer in place install the nut with the rebound elastomer on it. The radius'd side of the rebound elastomer should be facing out with the square side against the handle.  From the center section the it should look like this:  

Now install the bolt, ensure there is blue loc-tite on both the nut and bolt threads.  As when removing the elastomer it can be easier to turn the nut if pressure is applied downward through the handle unloading the tension on the bolt/nut from the elastomer.  Tighten the nut until the bolt bottoms out.  With the bolt bottomed out in the nut the bar will have 5* of up sweep.
