The Topcap Adapter is for extending the easyLoop system, allowing it to be installed on even more bikes. The adapter replaces the existing top cap, providing the option to install the Reverse easyLoop Adapter above the stem. There are several reasons why an installation above the stem may be necessary:
- For stems that require special spacers that cannot be replaced by the easyLoop Adapter. (e.g. C.I.S System)
- For bikes where the steerer tube has been cut too short and no spacers fit below or above the stem.
- For bikes where the easyLoop Adapter can be installed below the stem, but there is not enough clearance between the easyLoop Adapter and the frame.

Not compatible with stems where the top cap is integrated into the stem or that require a special top cap.

Note: No stem should be mounted on the Topcap Adapter. The adapter is not designed to extend the steerer tube and should only be used with the easyLoop Adapter!
