Find yourself wanting more out of your rear suspension? This RockShox air can kit will transform the way certain bikes ride and provide you with the ability to tweak the shape of your air spring.

Introduced alongside the Lyrik Ultimate fork and Charger 2.1 damper update, the MegNeg air can kit more than doubles today's already large negative volumes. This results in a noticeable and tunable boost of mid- and end-stroke support (and a lot more pumping). Join Vital MTB's Product Editor, Brandon Turman, to learn how it came to be, what the tuning process is like, the upsides, downsides, and an overview of what types of mountain bikes will gain the most from the MegNeg upgrade.

The MegNeg inches RockShox air shocks closer and closer to that coil feel while maintaining the ability to make quick pressure changes and adjust bottom-out support. It's fun to wrap your mind around and experiment with, seeing what works and what doesn't work for your bike and riding style specifically. There's a lot of tuning capability here, and this product will help people create more enjoyable rides.

If you are constantly banging off the bottom of your bike's travel, have that sucker stacked full of volume spacers, run the lowest suggested sag value and still aren't getting the support you're after, you absolutely want to consider the MegNeg.

You can tune compression stacks all you want, but addressing the spring curve is always more impactful. This is an excellent upgrade for a reasonable price and will make a big difference on bikes that could benefit from added mid- and end-stroke support. You've got to be willing to do some back-to-back testing though!
