Developed together with New York bike messengers, we created tube pads to be lightweight, wear resistant, and give enough protection to handle U-locking 7 days a week. Tube pads have anti-theft loop, which you can zip-tie to your frame to prevent unauthorized removal. Applied unique pillow-shape design, which lets you fit multiple tube diameters, which fits as tight at 1 inch frame as at 40 mm aero tubing , allowing brake cables inside.
