As many of you know, we have formed a partnership with ELKA suspension to custom-valve all available CHUMBA suspension frames to reach the pinnacle of performance with respect to your bicycle.  We have analyzed all of our frames with ELKA, to attain the perfect combination of compression and rebound depending on your weight, riding style, and frame you choose.

The proper amount of compression and rebound designed around your linkage is vital in suspension performance.  The EVO G2 uses a patent pending system, that alters the frame's suspension feel when using either a coil shock or an air shock.  Other frames don't make this differentiation.  The ELKA then further fine tunes this linkage and shock combo to give you unsurpassed performance climbing, descending, and handling all technical terrain.  In short, the performance is taken to new levels not offered by other manufacturers.

Here is what a rider who recently participated in this service had to say, "I am able to climb further up the same technical slopes than on my Ellsworth Moment or Ibis Mojo.  Does it mean that it is better?  I would think so.  Compared to the dw-link, the EVO G2 is definitely more plush, and the ELKA definitely helps...the rear end doesn't flex like the Ibis Mojo..."  

Attached, you will find a sample report that is made available at the time of shipping your frame. Sample PDF Report for Custom-valved Rear Suspension
