Delta System

AKA - Dave’s Extra Legitimate Travel Apparatus

As much as we would like to think that everyone will have the opportunity to test ride an Evil, the reality is most of you will buy based on reviews, friends, or Weagle's past successes.

So the following is straight from the horses mouth (Dave Weagle being the horse). The DELTA system was conceived to, among other things, achieve very complex leverage rate curves that can be used to tune for varying track conditions, spring, and damper parameters. The dual progressive leverage rate curve was developed for coil sprung downhill applications to take advantage of the speed sensitive shocks on the market. Mechanically, the system uses very compact links that can achieve a lot of angle and velocity change through the travel. We can tailor the leverage rate curve to really take advantage of the shock's valving and the way that a speed sensitive damper is designed to work. Ultimately the design achieves a high degree of suppleness early in the travel, with a very predictable high traction stage through the middle and a bottomless ramp at the end of the travel.

The whole suspension system, every attribute, is developed concurrently with each other, with the shock absorber, and with the bike's intended use and geometry in mind. Main pivot location was carefully chosen to give the best balance of acceleration and braking performance. This careful positioning lets the bike accelerate without the need for excess damping, which in turn helps us push the limits of shock setup as far as possible to achieve ideal damper setup for any World Cup track. One of the biggest advantages of the system is its ability to let riders and mechanics adjust frame geometry without changing leverage rate and wheel rate at all.

Behind the Black Curtain

Peer behind the curtain of Evil Bikes and see how we prep and build the rigs you know and love. Our rigorous QC and assembly process ensures that the bike arriving on your doorstep is ready to turn heads and stir up dirt before it leaves our headquarters in Bellingham, WA.

Unboxing

MTB Unboxing

Our packaging process aims to minimize the time between the delivery van and the trail. This video shows all the necessary steps to prep your newly ordered Evil.

Chamois Unboxing

The Chamois Hagar arrives 95% built but follows a slightly different unboxing process. This video shows that process and details resyncing AXS components if they become disconnected.

SETTING SAG

Dialing the suspension on your Evil is dead simple. Our bikes are built with the best suspension available, and setting SAG is the first step toward max performance.

The Flip Chip

At the heart of the Delta System, is a simple chip that we call the Flip Chip. At it's most basic, the Flip Chip allows riders to change bottom bracket height and head angle by flipping the chip. This adjustment, like we said above, leaves the leverage rate curve and orientation of the linkage unchanged. The slight offset in bearing bore creates a simple interface that allows the rider to personalize their ride. It's about finding what works for the way you ride and the terrain you ride in.

Re-setting your Revives Air pressure
