Bontrager Rhythm Pro Stem

Bontrager's Rhythm Pro Stem is engineered for the rigors and punishment of aggressive, all-mountain riding. Thanks to its forged 7050-T6 aluminum construction, it's strong, light and stiff. The CNC-machined 4-bolt faceplate is ultra tough and evenly distributes the clamping force on carbon bars. And, the opposing 2-bolt steerer clamp is safe and secure, even for carbon steerers.

Features and Information

  • See how stem angle and length are measured.
  • Clamp Diameter: 31.8mm
  • Steerer Size: 1 1/8 inch
  • Weight: 150 grams (100mm)
  • When installed on a carbon steerer, this stem requires at least 5mm of spacers above and below the steerer tube clamp area. Call us if you have any questions.
