Front Derailleur Braze-On Adapter Shimano SM-AD91 34.9mm

The adapter fits a 34.9 mm seat tube diameter and provides a secure and stable mounting point, even under demanding riding conditions. Precise compatibility and genuine Shimano quality ensure smooth and accurate front shifting on road, gravel and mountain bikes.

Its lightweight yet durable construction combines aluminium, stainless steel and carbon fiber reinforced polymer for optimal strength, low weight and long service life.
