The All-New Capital SL Wheels

THE FUTURE HAS ARRIVED

More than the sum of its parts, every element of the all-new Capital SL wheels has been designed to function as part of aSystem For Speed. The one-piece carbon design delivers a lighter, stronger and more responsive feel that will make you faster on both road and gravel.Faster acceleration, faster cornering, better handling and unreal Aero performanceis achieved on a wheelset barely tipping the scales. Ride the Future Today.

Monocoque Wheel System (MWS)

  • Deploying a system with low inertia, drag and rolling resistance which at the same time gives good handling and stability would not be possible without the right technology. Our innovative one-shot patented manufacturing technique is the best way to make the fastest wheel on the market.

  • By using the full potential of the material properties of carbon fiber available and a new manufacturing process, MWS delivers the best carbon fiber wheelset.

  • After curing, the spokes are pre-tensioned by an enforced displacement of the flanges followed by inserting and bonding of the bearing tube. A high precision jig ensures the correct and uniform spokes pre-tension.

AERODYNAMIC PERFORMANCE

From the outset, our engineers considered a range of riding conditions to deliver the optimum Aero Performance for the Capital SL. Riding speed, Wind Speed and Wind Direction were all considered from the beginning. The unique monocoque design delivers a 7% aero savings compared to our benchmark – even with a wider tire. As the wheel was developed as a system – wheel and tire together – we were able to balance Aero Performance with Rolling Resistance delivering the fastest overall system in all situations.

Computational Fluid Dynamics (CFD) optimization

Almost 200 configurations of the Capital SL wheel have been simulated with CFD technology, each of them at several different yaw angles. Shape optimizations of the rim geometry have enabled us to reduce the separation of the rim section at high yaw angles. This leads to a drag reduction and makes the wheel more predictable in windy conditions.

Wind Tunnel Testing

To optimize Aerodynamic savings, we took the unique one-piece design with carbon fiber spokes into the wind tunnel. Using a purpose built system that has been designed to measure the rotational and translational drag, we tested the designs for all-new Capital SL Aero and Capital SL.

To test the different rim shape configurations, we developed a specific metal rim with the same rim bed geometry as the final rim which is mounted on a prototyped model that accurately represents the outer shape.The spokes are modeled to have the same shape that the final wheel has.

  • With a hookless design, the rim's structure is improved, resulting in a stronger and lighter rim. Aerodynamically, the absence of the hooks leads to a smoother transition from the tire to the rim, which reduces drag.

  • Stiffness optimization is closely correlated to the handling feeling of a rider, and as such. is an area of focus. We drastically worked on this key component to ensure the best performance and feeling in all riding conditions.

  • The Capital SL wheels were developed looking at the wheel as a system including the tire and its rolling resistance. This led to the adaptation of wider tires offering lower rolling resistance.

CRASH REPLACEMENT PROGRAM

If your Syncros Capital SL wheel becomes damaged by a crash in a non-repairable way and the wheel cannot be used anymore you will have the possibility to take advantage of a special rate on a new wheel.

This offer is eligible for the first owner of the wheel up to 3 years from the purchase date. Depending on the age of the wheel, Syncros will offer you the following discounts:

  • In the first year after the date of purchase a 50% reduction is offered on the official retail price.
  • In the second year 30%.
  • In the third year a 20% discount.

The Capital SL wheels are also covered by a 2 year statutory warranty.

To do so please contact your authorized Syncros dealer to start the process. In case of further questions please do not hesitate to contact us.
