With thoughtful upgrades to the frame and components, the new PUBLIC D8i Disc LTD is a workhorse set of wheels built with the everyday commuter in mind. We’re confident this is one of our most functional and performance-oriented bikes yet.

The D8i Disc is constructed of high-quality, light-weight Chromoly steel that is strong and durable for everyday use and ensures a smooth ride for commuting, errands or longer jaunts on the weekend. The upgraded high-end Shimano Alfine 8-speed hub offers a wide range of gearing and delivers a smooth, silent ride that is virtually maintenance-free, while the Shimano hydraulic disc brakes offer easy, responsive stopping rain or shine. Daily riders will rarely need to worry about adjustments, maintenance or exposure to rain and the toughest of city streets.

Additional upgrades include our Premium Sport Saddle designed to give you the same comfort and performance of a well-worn leather saddle on your very first ride, a threadless headset, weatherproof grips, and minimalist, mirrored decals. Built to endure the long haul, the D8i Disc comes equipped with our strongest double-wall wheelset with color matching rims and puncture-resistant tires. Removable alloy fenders protect you from road grit and make sure you arrive looking sharp, and the integrated alloy chainguard keeps your clothes clean and dry. You won't have to roll up your pants leg to ride in style for the office or the evening.

Combining performance and urban practicality, the PUBLIC D8i disc is ready to deliver on almost any style of riding and is guaranteed to turn heads.  This bike is not eligible for our Ready to Ride shipping option due to oversize packaging restrictions.  We encourage you to select Partner Pickup at checkout or work with a reputable shop in your area to schedule an appointment for their mechanics to build and tune the bike.
