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.

Sway Alert!! This is a beautiful suite!
Color: Beige, Size: 5, Color: Beige, Size: 5
This suit fit great my son loved it. The quality is good. My son is five about 40 inches tall around 40 pounds. He’s very slim but the length was great. The suit jacket fit well. The pants waist were a little big, but the adjustable strap helped with that, but the fit overall was great . I would purchase a suit again in a different color.

Great Looking Suit with Lightweight Material
Color: Light Grey, Size: 7
I got this for a beach wedding and it worked out really well. It looked nice without feeling too formal, which was perfect for the setting. The material is linen and it feels lightweight and breathable. It kept my kid comfortable in the heat and didn’t feel stiff or heavy like some dress suits do. The appearance is sharp. The double breasted style makes it look more dressed up, but the linen material keeps it relaxed and appropriate for outdoor events. The fit was true to size. It sat well without looking baggy or tight, and everything stayed in place throughout the event. Quality feels good for the price. The fabric and stitching don’t feel cheap, and it held up well after a full day of wear. Suitability is great for things like weddings, parties, or photos. It works especially well for warmer weather because of the material. For value, I think it’s worth it. You’re getting a nice looking suit with comfortable material that actually works in real situations. Overall, great fit, breathable material, and a clean look that works really well for events.

Very nice linen suit for boys. Well worth the piece
Color: Beige, Size: 12
This JPF Double Breasted Linen Suit for Boys is the cutest thing I've ever seen! I got itt for my 8 year old and he loves it! He tried it on at soon as we received it and wore it all evening. Lol. He looks so grown up! He's about 4'3", about 75lbs. I ordered a size 12 and it fits him the way I'd expect it to. A bit big but he has room to grow into it. It is a 2 piece suit, with pants and blazer only. It's a summer suit, it's meant to have a more laid back, casual style. It is so nice! The style and color are identical to the photo. I got the beige color, that's the color my kid picked. I do worry a bit about staining, considering an 8 year old boy will be wearing it, but hopefully any stains will be easy to remove. The quality is excellent and the price isn't bad either. I highly recommend this suit
