R25-45 Wide-Road Rim 700c

With a 25mm inner width, this rim accommodates the latest 28C and 30C tires (WAM 29-32mm), reducing air turbulence at the tire-rim transition for optimal aero performance. The increased tire volume improves rider comfort and control, even on rough or poorly maintained roads. The 45mm rim depth strikes the perfect balance, offering versatility across varied terrains and conditions—whether it’s road racing, cyclocross, or light gravel. It’s built to handle all the challenges your customers face, from climbs to crosswinds.

Key Features:
1. Aero-optimized 25mm inner width for 28C and 30C tires
2. Lightweight design: just 320g with 2.25x the impact strength of UCI standards (40J)
3. Versatile 45mm depth—ideal for both competitive cycling and adventurous rides

With the NTP R25-45, you can offer your customers a high-performance, durable rim for any ride.

Product Testing

Impact Test

Impact Test

Our impact tests follow UCI standards for road, cyclocross, and gravel wheels—performed without tires. For MTB wheels, tests are conducted with tires mounted to simulate real-world conditions. Impact standards for private label products can be fully customized.
Stiffness Test

Stiffness Test

We measure both vertical and lateral stiffness to assess how the rim performs on specific terrain and the ride feel it delivers. A static force of 30kgf (lateral) and 50kgf (vertical) is applied to the rim during testing. Test conditions can be customized to meet your product or market requirements.
Tire Inflation Test

Tire Inflation Test

Strong tire retention under high pressure is a key indicator of rim quality. During testing, the rim width variation must remain within 0.2 mm to ensure consistency and safety. Test parameters can be customized to meet specific customer requirements.
Wheel Building Test

Wheel Building Test

A rim is only one part of the wheel system. We verify drilling angles, stiffness, and rim geometry to ensure seamless integration with spokes, hubs, and nipples.
Spoke Pull-Through Test

Spoke Pull-Through Test

Spoke holes are critical stress points. Each new rim design undergoes pull-through testing to ensure proper reinforcement. The minimum pull-out strength must exceed 320kgf to pass.
Greenhouse Test

Greenhouse Test

The Greenhouse Test is designed to simulate extreme conditions, such as when a wheel and tire assembly is exposed to high temperatures during transport in direct sunlight. This test is conducted in accordance with ISO 4210-7:2023, section 4.4.

Customization Services

We offer a wide range of customization options to help your rim and wheel products stand out — even when using shared open molds. From layup structure and stiffness tuning to surface finishes and branding, our private labeling solutions give you full control over product identity and performance.
