Our latest innovation, the result of our experience and knowledge over time. We present our best wheelset that is not only lightweight but also offers maximum stiffness. Each wheelset undergoes a strict process, from spoke tension release, alignment checks, to accurate measurements of flatness and uniformity of spoke tension.
Our latest rims utilize cutting-edge materials, a blend of T700 and T800, to provide optimal strength and stiffness at strategic points. With innovative geometry design and TRS technology, this wheelset offers low rolling resistance, providing exceptional comfort on every ride.
The Strummer carbon straightpull spokes used in this wheelset are designed to optimally support strength and aerodynamics. By using our own spokes, we are able to create a wheelset with a higher level of precision. This Strummer carbon spoke wheelset is assembled with spoke calculations that are 50% more meticulous, with length differences of up to 0.5 mm, compared to most other wheelsets that are generally calculated in 1 mm increments. This more precise sizing makes our wheelset more effective and closer to perfection.
Powered by the HR-700 hub with straightpull technology, this wheelset is significantly lighter than our previous road disc hub. Each element is processed with precision CNC, efficiently reducing material to achieve the lightest weight. The responsive 54T ratchet system mechanism not only enhances performance but also provides a satisfying riding experience.
Warnings & Special Attention for Strummer Carbon Spokes! Read Before Performing Repairs or Maintenance on the Product!
The Strummer carbon Straightpull spokes use a different system from conventional spokes. In conventional spokes, tightening and loosening are done from the inner diameter side of the rims. However, for Strummer carbon spokes, tightening and loosening from the inner diameter side of the rims is strictly prohibited, as it can damage the product and endanger the safety and security of the user.
To perform the tightening and loosening of these spokes, two types of tools are required:
- 3.4 mm spoke holder – Example: Park Tool SW-22
- Internal Nipple Spoke Wrench 5.5 mm – Example: Park Tool SW-15
Steps:
- Spoke Holder: Use a 3.4 mm spoke holder to hold the protruding part of the spoke on the inner diameter side of the rims. Ensure the spoke does not move while holding.
- Tightening/Loosening: Insert a 5.5 mm hex key from the outer diameter side of the rims to tighten or loosen the spokes as needed.
Very Important:
- Always use the appropriate tools to prevent damage to the spokes and rims.
- Please pay attention to this step to maintain product durability and user safety.

Innovation, Since Day One
Since our inception in 2008, we strive to make better products that can be depended on. Starting with our CAD technology. Our headsets remove unnecessary clamping to fork axle while providing identical performance. We are also one of the first to sell convertible hubs in Indonesia.
Pay Attention to the Details
We obsessively focus on the details. Improving by the millimeter. Adding the stiffness of our hubs by widening the flange of our hubs, thus increasing wheelset stability and strength.
