The D50 Compressor is the resulting product from real world racing experience. By gathering information and comments from the riders, RATIO developed a truly exceptional product. In fact, many bikers complained that many headsets loosen after few cycling rides and produce an annoying vibration noise. RATIO has examined and carefully studied the issue and noted the need to increase the contact surface between the inside of the fork tube and the expander to reduce unpleasant vibrations. By doing that, a greater expansion surface is also achieved. And here is the D50 Compressor: 50 mm surface, instead of 20 or 25 mm as all other commonly used expanders. The D50 Compressor from RATIO is super light and features a top cap in AL7075 alloy black anodized.
