Description
Will this work?
- Shimano Ultegra ST-6603 (L) / ST-6600 (R) STI
- 3×10 speed, triple front / 10-speed rear
- Integrated brake/shift levers for drop bars
- 26.0mm band clamp (clamps included)
- Flight Deck compatible
- Left and right shifter set with hoods
Condition: Excellent. Lever blades are bright and clean. Hoods are in great shape with no tears or hardening. Shifting clicks through all positions cleanly in both directions. Brake pivot action is smooth. These were well cared for.
Notes from MyBikeThing: The 6600-series Ultegra triple has become a go-to for touring and randonneuring builds — reliable 10-speed shifting with a triple front for loaded climbing. These are increasingly hard to find as a matched set in this condition. If you’re building a touring rig, this is the one.
Workshop Wisdom: Ultegra is the perfect shifter for that power steering feel (vs manual with Dura-Ace)
Guarantee: You put in the miles, we put in the work! 30 day Guarantee, rest assured of fit, function and condition 🙂
