This all-new R5 is an incredibly light (5.97kg in RED and Dura-Ace builds) road bike that’s also stiff enough to compete at the highest levels of professional cycling—as Pauline Ferrand-Prevot proved when she rode it to victory at this summer’s Tour de France Femmes.

The new R5 in a size 56 builds up to just 5.97kg, a full 900 grams under the UCI’s minimum weight limit. The frame is just 651 grams (size 56), and the fork is 298 grams. In addition to the 100g reduction in frame/fork weight, we’ve turned our attention to every single component on the bike, for a total weight reduction of 326g from all Cervelo components.

While the handling geometry on the new R5 is nearly the same (aside from a small change to BB drop to account for 29mm tires), we changed the fit geometry to match that of the S5. Whether you’re switching between the models like Team Visma|Lease A Bike or R5 is your only ride, you’ll be in a stronger position for the fastest group rides.

The all-new HB18 bar/stem not only dropped nearly 150 grams from the weight of the bike, but it also helps the bike be two Watts more aerodynamic than the previous R5. We applied learnings from the S5 handlebar to develop a comfortable, fast, and stiff handlebar, ideal for big days in the saddle and hard fights to the line. All bar sizes are UCI-legal, even in light of the most recent regulations change.
The new S5 and R5 feature advanced, one-piece bar/stem combinations that make 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 bikes, we 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.
Any rider that purchases a new S5 or R5 will be able to request an additional bar/stem in a different size at no extra charge. This request must be made via the Authorized Cervélo retailer where the bike was purchased, and must be made within the first 60 days of ownership. These new stem/bars will be provided by Cervélo free of charge, but any labor costs or cost of parts that may be required for removing and installing the bars will be the responsibility of the rider.
