Our latest innovation, the result of our years of experience and knowledge. We present our finest wheelset, which is not only lightweight but also offers maximum stiffness. Each wheelset undergoes a rigorous process, from spoke stress relief and alignment checks to accurate measurements of rim trueness and spoke tension uniformity.
Our latest rims use advanced materials, combining T700 and T800, to provide optimal strength and stiffness at strategic points. With an innovative geometric design and TRS technology, this wheelset offers low rolling resistance, providing exceptional comfort on every ride.
The Strummer carbon straightpull spokes used on 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 using spoke calculations that are 50% more precise, with length differences of up to 0.5 mm, compared with most other wheelsets, which are generally calculated in 1 mm increments. This greater precision 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 hubs. Each component is precision-machined using CNC, efficiently reducing material to achieve the lightest possible weight. The responsive 54T ratchet mechanism not only improves performance but also provides a satisfying riding experience.
Warning & Special Precautions for Strummer Carbon Spokes! Read Before Repairing or Servicing the Product!
Strummer carbon Straightpull spokes use a different system from conventional spokes. With conventional spokes, tightening and loosening are performed from the inner diameter side of the rim. However, with Strummer carbon spokes, tightening and loosening from the inner diameter side of the rim is strictly prohibited, as it can damage the product and endanger the user's security and safety.
Two types of tools are required to tighten and loosen these spokes:
- 3.4 mm spoke holder - Example: Park Tool SW-22
- 5.5 mm internal spoke nipple wrench - Example: Park Tool SW-15
Steps:
- Spoke holder: Use a 3.4 mm spoke holder to hold the spoke section protruding on the inner diameter side of the rim. Make sure the spoke does not move while being held.
- Tightening/loosening: Insert a 5.5 mm hex wrench from the outer diameter side of the rim to tighten or loosen the spoke as needed.
Very Important:
- Always use the appropriate tools to prevent damage to the spokes and rim.
- Follow these steps carefully to maintain product durability and user safety.

Rear Hub Maintenance Note (Freehub)
Grease lubricates the parts that come into contact with each other in the rear hub's freehub mechanism, helping reduce friction and wear. Removing all the grease solely to obtain a louder sound is not recommended. Without adequate lubrication, components may wear out or become damaged more quickly, shortening their service life. Use the type and amount of lubricant recommended for product maintenance.
Shimano 12-Speed Compatibility
The Aeroflow Xtreme HR-700 supports Shimano 12-speed cassettes with the appropriate HG Road standard. If the cassette uses Microspline, a compatible Microspline freehub is required.
Conversion to Quick Release
It can be converted to QR using the appropriate adapters/end caps. Match the frame and fork sizes; for a 135 mm QR rear, use a 10×135 end cap compatible with the HR-700.
