Cervelo HB19 One Piece Handlebar Stem

HB19 uses Cervelo's “Plus-Four” concept, meaning the dimension at the hoods is 4cm narrower than in the drops (e.g. 38cm/42cm). This approach helps riders maintain a more aero body position while their hands are on the hoods, and provides stability in the drops for descending and sprinting. All bar sizes are UCI-legal, even in light of the most recent regulations change.

The new S5 features an advanced, one-piece bar/stem that makes both bike and rider faster. However, we know that achieving a perfect fit is a critical component to not just speed, but comfort on the bike. As part of our development of the new bike, they made a number of additional stem length/bar width combinations to make sure all riders can get as close to their ideal fit as possible.
