"If you're offered a seat on a rocket ship, don't ask what seat! Just get on."
? Sheryl Sandberg
The Fizik Tundra M5 VS Kium rail saddle is your seat on your rocket ship. Comfortable, lightweight, hungry for XC, the Tundra M5 features a carbon reinforced nylon base with Wingflex technology that is stiff enough for powering up steep climbs, yet flexible enough to keep the ride smooth and supple; a perfect combo for smashing the cross-country course.
The extended saddle length provides more riding position options, while the Wing Flex technology allows the shell to flex downward in the critical area where the inner thighs contact the saddle, allowing for a more efficient, full-range movement while pedaling. Spanning the length of the saddle is an ergonomic channel that acts as a pressure relief zone to keep blood properly flowing through the perineal region. For 2016 the Tundra M5 sees a new softer foam formulation to increase comfort while maintaining its superior support.
On top of it all, Fizik's unique integrated clip system is a built-in clip receiver for attaching Fizik accessories, such as bags and lights, for simplicity, practicality, and security.

DT Swiss has released a new high engagement hub for trail and gravity riders.The new DEG hub still utilizes DT Swiss' ratchet system, but the ratchet itself is almost twice as big as the current ratchet in order to match the large hub shell of the new hub. The max number of teeth available used to be 54, but the new DEG ratchet has grown to 90 teeth, which provides 4º of engagement angle, greatly reducing the play between engagement points.
For 2025, Fox has come out swinging with an all-new lineup of forks and dampers.

There have been some pretty solid improvements in performance and longevity of this line of suspension and we're excited to share the information with you!
Race Face has recently released the new Era carbon wheels, with many features that rival some of the best carbon wheels available on the market. Race Face was nice enough to invite us up to check out their new products and take them out on the trail to get a feel for ourselves. After just a matter of hours spent on these wheels, we're extremely impressed and wanted to drop a video going over some of the features that makes us think that they're some of the best carbon wheels available on the market.
The Norco Optic and Sight are a couple of the most popular trail and all-mountain bikes available, respectively. New for 2024, Norco has completely updated their suspension platform, moving from a traditional 4-bar design to a high-pivot 4-bar design to increase versatility. No matter how much travel you choose, a high pivot bike will be able to punch above its weight class.
