The OG DISC is built for riders who appreciate the smooth ride feel of steel but still want the responsiveness and efficiency of a modern road bike. Whether it’s fast road rides, long days in the saddle, or everyday riding, OG DISC keeps things balanced, comfortable, and predictable.
Constructed from MKPT seamless heat-treated double- and triple-butted chromoly tubing, the frame delivers a solid riding feel without losing the natural comfort steel is known for. The heat-treated chainstays help improve power transfer while keeping the bike stable and composed under hard pedaling.
Clearance for up to 700x32C tires gives extra flexibility for rough pavement, all-road riding, and longer-distance comfort without sacrificing the quick handling feel of a road bike.
Flat-mount disc brakes provide clean integration with reliable braking performance in all conditions, especially during fast descents or wet weather riding.
Details like the steel fin dropout and machined double-collar headtube bring a timeless steel bike character while blending naturally with the modern frame design. ED coating inside and out helps protect the frame for long-term durability and everyday use.
Simple, fast, and comfortable in its own way, the OG DISC is made for riders who still believe a good steel road bike has something special that modern materials can’t fully replace.
