Strummer Superdura SLR HR-800 Carbon Disc Brake Wheelset

Strummer Superdura SLR HR-800

Performance does not come from a single innovation.
It was born from experience, testing, and an obsession with detail.

Strummer Superdura SLR HR-800 was developed to deliver a modern road wheelset that balances power-transfer efficiency, high-speed stability, and real-world riding comfort.

With a 23 mm inner width, this rim profile follows modern road-performance standards—supporting wider tires for better grip, greater stability, and more optimized rolling efficiency than the previous generation.

With its exceptionally low wheelset weight, the HR-800 is also an ideal choice for climbing performance, helping maintain momentum on long climbs while delivering noticeably more responsive acceleration whenever exiting a corner or navigating a change in gradient.

Next-Generation Materials & Structure

The rims use a T1000 high-modulus carbon blend, delivering a combination of:

• Very lightweight

• High structural stiffness

• More direct acceleration response

Combined with the latest rim geometry design and TRS (Tubeless Ready System) technology, this wheelset provides maximum tire-use flexibility.

TRS allows the use of both tubeless and regular clincher tires.
This means the wheelset remains easy to use with a familiar conventional tire setup, while still allowing for a future upgrade to a tubeless system without replacing the wheelset.

In addition to setup flexibility, the TRS design also helps optimize rolling resistance and improve riding comfort across various asphalt conditions.

Precision Wheel Engineering

Each wheelset undergoes a multilayered quality-control process:

• Spoke tension release

• Alignment inspection

• Rim flatness measurement

• Spoke tension uniformity verification

Strummer Carbon Straightpull Spokes are manufactured with a high degree of precision, using length tolerances of up to 0.5 mm—approximately twice as precise as the general industry standard (±1 mm).

This level of precision helps produce a more balanced wheel structure, more efficient power transfer, and more consistent long-term performance.

HR-800 Ratchet Hub System

This wheelset uses the HR-800 Straightpull Hub with a 54T ratchet engagement system for fast, responsive acceleration.

All hub components are processed using high-precision CNC machining to maximize material efficiency without compromising structural strength.

Compared with the previous generation of road disc hubs, the HR-800 is designed with a focus on:

• Weight reduction

• Higher rotational efficiency (due to ceramic bearings)

---

Designed for Real Road Performance

This wheelset is optimized for road performance riding on asphalt surfaces, with a focus on:

• Stability at high speeds

• Efficient power delivery

• Long-distance riding comfort

• Climbing efficiency thanks to the extremely lightweight wheelset

Designed for today’s performance while also being ready for the future of riding technology.

⚠ Special Attention – Carbon Straightpull Spoke System

Strummer Carbon Straightpull Spokes use a different system from conventional spokes.

With conventional spokes, tightening and loosening are performed from the inner rim diameter side.
For Strummer carbon spokes, this method is strictly prohibited, as it can damage the product and endanger user safety.

For spoke servicing, you must use:

• Spoke Holder 3.4 mm (Example: Park Tool SW-22)

• Internal Nipple Spoke Wrench 5.5 mm (Example: Park Tool SW-15)

Always use the appropriate tools and follow proper service procedures to maintain the product’s service life and user safety.
