Description
What do I need to know about this headset?
Shimano’s 600 groupset wasn’t just a product, it was an era. Debuting in the 70s and reaching its peak in the late 80s/early 90s, the 600 embodied reliable performance for everyday riders. While eventually succeeded by the higher-tech Ultegra, the 600 holds a special place in cycling hearts.
Why the Shift? Shimano aimed for a more modern, racing-oriented image with Ultegra. But the 600’s legacy lives on. Praised for its durability and user-friendliness, it’s the ideal choice for vintage restorations and a favorite among enthusiasts.
Condition
In excellent condition. I threw this in my ultrasonic cleaner and it unfortunately cleaned off the 600 logos. There are some marks to the bolt heads from removal, but otherwise in great shape. Threads are excellent, no missing bearings, and the races are smooth and clean.
