Di2 routing can be a bit of a mess on a tri bike, where aerodynamics can cost you time. The Aeroport RS910 Adapter cleans up your junction box, BTR2 internal battery, and SD50 cables for maximum efficiency and tidiness.

The adapter fits the BTR2 internal battery and Aerosport RS910 bar end junction into the rear of a set of aluminum extensions or 35c+ extension, making the battery placement and cable routing through the frame more secure. It also gets ri of the mess of cables typically seen with an EW junction box and prevents the need to hide the junction box in the stem or frame.

• Adapter houses Di2 components for a cleaner cockpit
• Fits internal battery and bar end junction into the rear of an extension
• Eliminates messy junction box cables
• Adapter will not fit in aerobars where the rear extension is not accessible
• Di2 parts not included with the adapter
