Vitus Nucleus 29 VRS review

May 2021 · Alex Evans

Despite some decent parts, the Nucleus has a disappointingly stiff and XC-biased ride

Highs
  • Shimano Deore-based drivetrain works well

  • Good grip from tyres in most conditions

Lows
  • Geometry compromises all aspects of performance

  • Fork suffers from stiction

  • Stiff-feeling ride

Vitus Nucleus VR - MBR

Dec 2019 · Alan Muldoon

What can we say about the Vitus Nucleus 27 VR that’s not been said? As winner of this test four years in a row, its accolades say everything.

Highs
  • Ride quality and build kit belie its price tag

Lows
  • Still no clutch mech to help keep the chain on
