Shimano Sora ST-3503 9-Speed Triple Shifter Set
Notes from MyBikeThing The ST-3503 Sora shifters deliver reliable performance with Shimano’s proven dual-control design, featuring their classic black finish and ergonomic hood shape. The internal mechanism uses Shimano’s trusted 9-speed indexing system with positive click engagement. What sets these apart is their optical gear display window, making it easy to confirm gear position while riding.
Condition Internal inspection shows clean mechanisms with proper spring tension and pawl engagement. The black finish is well preserved with normal wear. Hoods are supple and intact with no tears or degradation. Windows have yellowed and faded. Need better pictures or have questions? Reach out – no AI, no voicemail, just direct conversation about bikes. “You put in the miles, we put in the work! 30 day Guarantee, rest assured of fit, function and condition.”
Workshop Wisdom These shifters benefit from annual cable replacement – when installing new cables, pre-stretch them under tension before final adjustment to prevent shift drift after installation.
