Specialized Turbo Levo 4 Comp Alloy 2026 E-bike review: Frame
The Gen 4 frame introduces significant geometric refinements. The structure is based on the S-Sizing system, which prioritizes riding style (more agile or more stable) over the rider's height alone.
Adjustable Geometry: Thanks to the Flip Chips on the rear pivot and eccentric headset cups, the head angle can be adjusted from 63.5 to 65.5 degrees.
Mullet Configuration: The 29-inch front wheel ensures obstacle rollover, while the 27.5-inch rear wheel keeps the chainstay compact to favor responsiveness.
SWAT Compartment: Even on the Alloy version, there is integration in the down tube for carrying tools—a unique functional design plus in the industry.
