Why our Vert Junkies® love this

Fast bike. Sharp fit. Zero fluff.
The RK90 is a 273 gram saddle, plus or minus 10 grams, built for high cadence road days, MTB laps, and long, low TT positions without the dead weight feel. Big center cutout. Slim nose. Race ready shape.

Key Features

  • Ultralight build: 273 grams, plus or minus 10 grams

  • Size: 270 x 140 mm platform for a locked-in, efficient stance

  • Full-length center cutout for pressure relief in drops and aero positions

  • Chrome-moly steel rails for durable clamping and hard use

  • High-grade EVA padding that supports without turning mushy

  • Nylon cover for grip and wear resistance

  • Engineered plastic base for stiffness where it counts

  • Four colorways: Black, Black with Red speckle, Black with Blue speckle, Black with Green speckle

Recommended Use

Run it on MTB, road, TT, tri, and trainer builds where grams matter and the position stays forward.
Best for riders chasing a clean pedal stroke, stable sit bone support, and cutout driven relief during long efforts.

Bottom Line

Cut weight. Keep pressure off. Hold speed.
