Product Details
Key Features
C/Series Carbon Frame – Over the course of hundreds of virtual simulation comparisons and back-to-back carbon prototype testing, Yeti has refined their carbon layups to deliver consistent torsional stiffness and flex profiles across all frame sizes. The feel is precise yet compliant while structurally balancing light weight and durability.
Travel – 160mm Front / 140mm Rear
Wheel Size – 29"
Lunch Ride – The "LR" designation stands for "Lunch Ride" edition, which features 10 mm more travel at the front than the conventional SB140 model & is designed for enhanced fun & stability.
Switch Infinity Suspension – The new line of Yeti Switch Infinity bikes builds on their award-winning performance with subtle refined leverage rates that have been adjusted for the added travel of each new bike. This balanced approach to leverage rate results in an incredibly predictable ride.
Internal Cable Routing – Internally routed cable tubes with secure closures at entry and exit points eliminate rattles and cable rub. Whether running a mechanical drivetrain and dropper or a wireless setup, cable management is intuitively easy and quiet.
UDH Compatible – If a hanger bending crash occurs, the new Yeti models use the Universal Derailleur Hanger (UDH) interface — the industry standard mount for a rear derailleur. The UDH is available in nearly any bike shop, Yeti dealer or not.
