SB5 Beti Carbon GX Eagle Complete Mountain Bike

The Yeti Beti SB5 uses a frame that's identical to the critically-acclaimed SB5, but with a lighter shock tune as well as touch points (grips, handlebar, saddle) that are better suited for smaller and lighter riders. Born on the rugged trails of Colorado, the Beti SB5 represents everything a modern trail bike should be: lightweight, nimble on the climbs, and dominant on the descents. With 5in of bump-gobbling Switch Infinity travel out back paired with a 6in travel Fox 36 fork up front, this bike is capable of tackling everything from all-day rides on raw backcountry singletrack, to quick laps at your local trail network, or even ripping the bike park on the weekend. On this SB5 Beti Carbon GX Eagle Complete Mountain Bike, all parts are high-performing and durable enough to withstand multiple seasons of use while coming in at a price point that leaves you enough to fund riding trips to epic mountain bike destinations to see just how far you can push this bike. For 2019, Yeti beefed up the fork stanchions from 34 to 36mm for more lateral and torsional stiffness on the front end to help it track better, and also gave the bike clearance for up to 2.8in wide plus tires. This significantly expands your tire options so you can run the right tread for the conditions at hand. Whether it's fast-rolling 2.3's for snappy handling on buff singletrack, meaty 2.5 or 2.6's for a mix of rugged conditions, or high-volume 2.8's for the chunky rock ledges of places like Moab, the SB5 can run them all. This build comes with 2.6in tires that find a nice middle ground between ground-hugging traction and reasonable rolling resistance.

A huge part of the Beti SB5's success is the Switch Infinity suspension design. It's certainly one of the best platforms we've ridden, made so by the translating main pivot with two Kashima-coated stanchions that switches directions as you move through the travel. The mechanism moves upward in the initial travel, providing excellent anti-squat characteristics in the pedaling zone for superior pedaling performance and mid-stroke support, all without sacrificing small-bump compliance. The link switches directions and moves back downward as you get deeper into the travel, dropping the anti-squat drastically and decoupling chain forces from the suspension, allowing the rear shock to better absorb impacts. Simply put, Switch Infinity is buttery-smooth throughout the entire travel, inspiring confidence on technical descents while remaining exceptionally efficient on the climbs by preserving your energy with minimal suspension bob.

We'd be doing you a disservice if we didn't talk about Yeti's carbon and the bike's geometry. This build is constructed from Yeti's C-Series carbon fiber, making for a frame that weighs just over 6lb with shock, depending on the size. This puts the bike on the lighter end of the trail bike spectrum despite the minor 250g weight penalty compared to the Beti SB5 frame made of TURQ carbon. This weight difference is due to a different carbon lay-up that allows Yeti to offer the C-Series frames at a lower cost, without sacrificing strength, stiffness, or ride quality compared to the TURQ frames. Yeti is quite confident in their carbon so starting in 2019, all frames come with a lifetime warranty against defects in materials and workmanship, including the Switch Infinity link itself. Available in sizes ranging from extra-small to extra-large for riders from 4'11 up to 6'6, the slack geometry inspires you to test your limits, while the low-slung top tube and short standover height give you confidence to lower your center of gravity for more control on tricky sections of trail, as well as easier dismounts in surprise situations.
