Shimano XTR Di2 SM-FD905 Front Derailleur Adapter for FD-M9050/FD-M9070

The Shimano XTR Di2 SM-FD905 front derailleur adapter is a component specifically developed for the electronic front derailleurs FD-M9050 and FD-M9070 of the Shimano XTR Di2 group. These adapters enable the front derailleur to be mounted on different frame constructions, offering a flexible solution for various mountain bikes. Shimano provides several variants for this purpose, which differ in their mounting type and weight, to meet the requirements of different frames and preferences.

For direct mounting to the seat tube, the SM-FD905-D adapter is available, representing a lightweight option at approximately 13.8 grams. Another option is the adapter for bottom bracket mounting, designated as SM-FD905-E, which weighs approximately 27.1 grams and allows for stable attachment to the bottom bracket area.

Furthermore, there are two clamp band variants suitable for frames that do not offer a direct mounting option on the seat tube. The "high clamp" adapter, SM-FD905-HX, weighs about 33 grams and is designed for seat tube diameters of 34.9 mm, with adapters for 31.8 mm and 28.6 mm diameters included. The "low clamp" variant, SM-FD905-LX, is slightly heavier at approximately 38.5 grams, but also offers compatibility with 34.9 mm tubes as well as adapters for 31.8 mm and 28.6 mm. This selection of adapters ensures that the Shimano XTR Di2 front derailleur can be mounted precisely and securely on a variety of mountain bike frames.
