Same performance level as the CD, but designed for triples. Will work with standard road triple cranks, but it is optimized for smaller rings such as 48-36-24t or 50-36-30t.
• Braze-on style, but this includes an adapter clamp for 28.6, 31.8 or 34.9mm.
• Two models:
Alpina-d is designed to work better with Shimano's drop bar/STI shifters.
Alpina-f is designed to work better with Shimano's flat bar road shifters.
