Tioga Power Block OS20 Tire

20" IS FAST OS20 is FAST2!What is OS20 PowerBlock?OS20 is NOT 22". OS20 is 20", but bigger. There are two wheel sizes under the 20" category – the 20" on Jr/mini bikes uses the 451mm diameter wheel in narrow widths (for 20-1/8" & 20-3/8" tires), and the conventional 20" which uses the smaller 406mm diameter wheel but in wider widths. OS20 is 451mm wheel diameter in widths similar to 406mm wheels. OS20 tires are not compatible with Jr/Mini sized rims; OS20 rims are not compatible with Jr/Mini sized tires. Why OS20? OS20 rolls faster and retains greater forward momentum. This is achieved by a few factors. First, it is well understood that minimizing the energy loss from the tire casing's deflection is key to reducing rolling resistance. The tire's sidewall compressing when weight is applied is one example of casing deflection. When compared with 20", OS20, with its larger diameter and greater air volume, exhibit a smaller proportion of its casing deflecting as it rolls – so smaller casing deflection, less energy loss. Second, the shape of the tire's contact patch also affects rolling characteristics. The contact patch the shape of the tread as it meets the ground. OS20 tire's larger air volume creates a different contact patch due to less casing deflection (see above). OS20 tires exhibit a smaller footprint resulting in lower rolling resistance. Another benefit of smaller casing deflection is being able to maintain more forward momentum. As larger diameter tire casings deflect less when rolling, less energy is wasted in overcoming the casing deflection, thus more forward momentum is maintained. OS20 has potential for higher top-end speed and more efficiently maintains the speed. When the difference between first and second is a fraction of a second, OS20 has the potential to be your winning edge. Is OS20 legal? Independently verified, OS20 wheel and tires are within UCI and USA BMX sizing regulations for 20”. What do I need for OS20? OS20 specific frame, OS20 specific wheels and tires (including OS20 rim strip and OS20 innertubes) are essential for OS20. Many current front forks made for 20” bikes will work with OS20. we stock the alienation OS20 rims and can build you a set up today!
