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.

FEATURES:

  • V is for Velocity: 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.
  • Frame Enhancements: 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.
  • Turbulent Aerodynamics: Reserve and Cervélo put our heads together to develop a completely innovative way of engineering and testing wheels to perform optimally in turbulent aerodynamic conditions. Wind tunnels usually measure performance in ideal "laminar" flow situations. But such conditions are unrealistic in the real world. So we helped Reserve develop rim profiles that stall less dramatically at greater yaw angles; in riding terms it’s more stable, more planted, and thus more confidence inspiring. It makes you go faster because you feel more comfortable going faster. The Reserve 52/63 is 50g faster in laminar (traditional) flow, and 54g faster in turbulent flow than the outgoing Reserve 50/65 combo.
  • Tire Clearance: 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.
  • Handlebar Refinement: 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.
  • Keeping it Simple: 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.

Great for the price
Size: 9.25in 1 Pack, Size: 9.25in 1 Pack
It’s great, easy to put together, looks nice for a lazy susan but I might be returning it bc it doesn’t hold all my spices in my cabinet. I wish the tiers were spaced out more evenly so taller spices would fit on the top.

Great shelves
Size: 16.5 Inch, Color: Rustic Brown
I loved these for my room, they were easy to install and super versatile, I love how easy it was to assemble them and how functional they became once I was done setting them up. They fit perfectly next to each other and I love how my room looks nice since I don't like relying on bookshelves or anything of that category and rather have wall shelves. They are really stable and I love how they look, they are also really easy to clean since I spilled some baby powder from my last waxing session and they clean up pretty well. Overall, just know that these shelves are super stable, durable and versatile, I love how many things can fit on it if you know how to organize or don't have much stuff to put on them; it's all up to you and what you need them for, so I recommend them 10/10!

Great shelves! Had for years!
Size: 16.5 Inch, Color: Rustic Brown, Size: 16.5 Inch, Color: Rustic Brown
I love these shelves, I’ve had them set up both ways, as a floating shelf and the other way where you get some side support. I’ve had them for years, moved with them, and they continue to work great. I’ve had a lot on them too weight wise (I love books) and they don’t cave in the middle. Great shelves and easy to assemble (I’m a newbie with a drill). Great value for the money, durability is great, adjustable, and great for what you get!

Budget-Friendly with a Rustic Charm - WOPITUES Wood Floating Shelves Set of 6
Size: 16.5 Inch, Color: Rustic Brown
The WOPITUES Wood Floating Shelves Set of 6 is an appealing option for those looking to add a touch of rustic charm to their home without spending a fortune. This set of six shelves offers great versatility and functionality, ideal for displaying a variety of items such as books, plants, and decorative pieces, enhancing any wall decor with a farmhouse vibe. Upon installation, which is straightforward with the included mounting hardware, these shelves provide a neat and organized look. The ability to arrange them in various configurations allows for creative freedom in decorating, making it easy to personalize your space. The overall capacity and sturdiness of the shelves are commendable, holding up well under the weight of typical decor items. However, while the shelves perform well from a distance, a closer inspection reveals that the materials look somewhat cheap. The wood finish, although attractive from afar, does not hold up to close scrutiny, with the texture and detailing lacking the quality one might expect from more expensive shelving. This aspect might be a downside for those who prefer more authentic, high-quality woodwork. In conclusion, the WOPITUES Wood Floating Shelves are a solid choice for anyone on a budget looking to enhance their home decor. They offer good functionality and aesthetic appeal at a distance, though they may not satisfy those looking for premium material quality. For the price, they are a worthy consideration for casual use and decorative purposes.

Good product. Real wood. Sturdy wall anchor.
Size: 16.5 Inch, Color: Black
4.5 stars. It's a great product. The pictures made me wonder if this was wood or plastic, but it is definitely wood. It is very attractive and fairly easy to assemble. I feel like the harnesses for the wall don't fit the wood well enough, so you can get different distances from the wall, and one of my shelves is half a centimeter below the others, even though I lined it up the same. But they are sturdy shelves and very pretty. My only real complaint is the screw anchors for the walls. They are SERIOUS. I doubt these will ever fall out of the wall, for real. The only problem is, they eat the wall as you are putting them in. If I ever decide to move these, I will have to do some serious dry wall repair.
