2025 CERVELO S5

The S5 has one job—get to the line before everyone else. Under the likes of Wout van Aert, Marianne Vos, and Christophe LaPorte, the new model has already proven itself as a tool without equal. In the 2022 Tour de France, this bike propelled Wout to the highest ever Points Classification score of the modern era. At 480, Wout was some 194 points ahead of his nearest rival—tangible proof that Cervélo keeps delivering aerodynamic gains to our World Tour athletes.

The new S5 has reduced drag by 65 grams, and increased the frame’s surface area while still reducing overall weight. The deeper frame sections maximize the shapes allowed by the UCI. Meanwhile the iconic V-stem has been further refined and a new fork designed to simplify the entire front end.

What’s more, a ground-breaking new wheel design concept has been co-developed with Reserve to increase stability and reduce drag in turbulent aero conditions.

In pursuit of speed, everyone wants to try different positions to find their most aggressive fit. The S5's iconic V-stem not only inspires confident handling at high speeds, it's now also remarkably simple to dial in your perfect set-up. All the necessary spacers come with the bike, and there’s now only one bolt length, reducing complexity and making the system 53g lighter in the process.

Wider wheels and tires are faster aerodynamically, and more comfortable to boot. S5 comes specced with 28mm tires but has clearance for up to a 34mm (measured) tire. The frame is optimized to complement the wider Reserve 52/63 turbulent aero wheels. In addition to the handling benefits, this saves over 5 watts compared to the previous Reserve wheelset.

The UCI’s new regulations on aerodynamic design allowed us some additional room to deepen our aero profiles and squeeze 65 more grams of drag performance out of what is already the fastest aero bike on the market. You’ll notice a deeper head tube and BB area, and more aggressive shaping on the trailing edges of the tubes. Since the new S5 is only compatible with electronic shifting, we were able to tidy the dropout a bit, and update the shaping all over the bike.

We’ve improved the comfort of the handlebar, and tweaked the shape to get a perfectly flat bar-to-hood transition. We now use a two-bolt interface that allows for infinite tilt adjustments between 0 and 5 degrees.

Bike fitters at every level are moving away from longer-offset seat posts, and the new S5 comes stock with a 15mm offset post on most sizes (vs 25mm offset on outgoing S5). The old seat posts are forward-compatible, and we’ll keep the 400mm-long, 25mm offset post in stock for those looking for a more extreme fit.

Red and Force builds include Quarq Zero powermeters integrated into the crank. The integration of a powermeter results in better stiffness, lighter weight, and improved accuracy over aftermarket solutions—and the DZero delivers power measurement accurate to +/- 1.5%, even in variable temperatures.

I've ordered a bike for pickup. Will it be assembled?

Absolutely! We take care of all the assembly work for you. Our experienced mechanics ensure that every bike is fully assembled and goes through a safety check before it's ready for you to collect. So, if you'd like, you can even ride it home from the shop right away!

Just a small note: a few bikes might not come with pedals included, so you might need to buy those separately. If you have any doubts or questions, feel free to ask us!

When will I get my order?

We strive to process and dispatch parts orders promptly. If we receive your order by 12 pm from Monday to Friday, we aim to have it shipped out on the same day. However, during peak sales or exceptionally busy periods, there might be delays.

Once your order is on its way, you will receive tracking information from our carriers, which will allow you to monitor the delivery progress.

For more specific estimated delivery times, we recommend visiting our carrier's website.

If you need further information or have specific shipping inquiries, please refer to our Shipping Policy or get in touch with our customer support team for additional details.

Can you ship a bike to me?

Certainly! We offer bike shipping directly to your home. When your bike arrives, it will come fully assembled, although some basic mechanical skills and tools may be needed for the final adjustments.

If you're unsure about assembling the bike yourself, we highly recommend seeking assistance from a local bicycle mechanic. Please note that if you choose to have a third party assemble or inspect your bike, any additional fees incurred will be at your own expense.

Our goal is to ensure that you receive your bike in the best condition possible, and we're here to support you throughout the process. If you have any questions or concerns about the shipping or assembly, please don't hesitate to reach out to us.

Can you post overseas?

We're sorry, but we are unable to ship our products overseas. Our shipping services are limited to within our own country, and we do not facilitate shipments to international destinations.
