Shimano Ultegra FC-6603 Triple 39T Chainring View Larger Image

OE Shimano Ultegra 6603 triple specific, 10 speed middle chainring. Although it is a 130mm bolt pattern, the teeth are profiled to match rings on both sides - hence it is a true "middle" chainring. It receives the same treatment as other Ultegra 6600 series rings - hard anodizing, ramping and pinning. Classic Ultegra: great product, great price.
