Can't stop, won't stop.

These days, being a woman in the mountain bike world is certainly starting to seem less challenging, and more welcoming. More capable, aggressive, and burly bikes are being made for us, catering to our wants and needs, and the world of shrink-it and pink-it is beginning to dissipate. With our needs in mind, Yeti's designers offer us the Yeti Beti SB5 Turq Mountain Bike Frame. With all the burly bells and whistles that are offered to the boys, the Beti SB5 is ready to shred any trail, and a couple of ladies-specific tweaks make it even more playful and fun. Saddle up and you just may find yourself sending it down the mountain as an unstoppable force to be reckoned with.

Head to toe, or rather, head tube to chainstay, you'll find the Beti has the same geometry as her brother. With a slacked out, confidence inspiring 66.5-degree head tube, she wants to send it down any trail you point her, and her generous 46-inch wheelbase (medium), she holds strong so you can barrel through bouldery rock gardens where hesitation can be the killer. In effort to prevent sluggish and cumbersome climbing, the bike's seat tube angle saw a forward shift, keeping your body forward on the bike for maximum attack positioning, and efficiency when you have to put down the power.

Short and snappy chainstays make up the rear, which saw a makeover in 2017. The longer chainstays and narrow non-boost spacing was stretched out to 148mm boost spacing, an increase of space afforded the room needed for tucking the wheel closer to the seat tube, and shortening the chainstays to a stubby 17.2in. Shorter chainstays translate to a playful and responsive rear end, happy to pop off of rollers, and help you maneuver through tight and root-laden switchbacks.

Just ahead of the rear triangle, tucked in the bottom of the frame, you'll find the —ahem, pivotal Switch Infinity suspension system. Different from the previously used Switch Link, Switch Infinity offers more linear travel arc, smoothly transitioning to keep the eccentric link from getting caught in a dead spot. Switch Infinity moves steadily through the beginning of your travel, moving a slider along it's Kashima coated stanchions, offering support when you put the power down with anti-squat technology, while still offering small bump compliance to keep the ride comfortable on gravely fire roads. When you begin to compress deeper into the travel, the bearings on the downhill-inspired-slider pivot to travel toward the bottom bracket so you don't lose power mid-pedal stroke. When you've finally made it to the top and are starting your well-earned descent down rock gardens and rooty single track, the suspension works with the upper pivot to provide a path for your wheel to travel vertically to smooth out burly square-edge impacts from a drop to flat, or a tire-hungry rock that came out of nowhere.

Pairing Kashima coated stanchions of Switch Infinity with more of that silky-smooth coating, the Beti SB5 Turq frame comes along with Fox's Factory DPS, Kashima coated rear shock. The shock is where we find the major difference setting apart the Beti from other Yeti bikes. With most ladies on the trail coming in 30lbs shy of the guys out there, men's shock tunes can feel harsh underneath our load, so Yeti offers a custom tuned shock just for us, giving us a more comfortable and responsive ride. Offering supple support as you roll down the mountain, the Factory DPS gives you 127mm of bottomless-feeling travel with adjustable tuning and rebound for the quick changes you need to make when terrain switches from a 14-mile flowy descent, to miles of tedious and exposed climb back up.

Adding to the bells and whistles, this frame is made from Yeti's highest-end carbon fiber — the Turq series. Meticulously laid carbon fiber bonds around a mold to cure with minimal pooling, reducing weight, and increasing strength in joints without excess material being added. Turq is the cream of the crop in the world of carbon fiber bikes, with minimal margin for error, and exceptional weight savings, Turq frames ride with unsurpassable durability for a solid and smooth ride on any trail.

  • Devour mountains on this women's specific 27.5 bike
  • 5-inches of Switch Infinity suspension smooth your ride
  • Ladies' specific shock tune supports lighter weight riders
  • Corner with power and precision with short and nimble chain stays
  • Cream-of-the-crop Turq carbon fiber pairs stiffness and light weight
  • Handles descents like a dream without compromising climbing
