Features

Release Option
Tired of unscrewing the base from the board after a session just so the board fits into the board bag? The iBase 2.0 has a release option for removing the connection joint simply by pulling the sand-resistant, stainless-steel U-pin. Without tools, you can swap between a conventional Powerjoint and the iTENDON in seconds. With a spare joint or tendon you are also immediately ready for action again if the worst comes to the worst – without having to repair the joint or tendon.

Perma Lock Option
For all safety nuts, the release button can be fixed with a screw, which disables the release function.

Stuck Solution
Should the iBase 2.0 ever become stuck to the board after long storage, two holes let you use a screwdriver as a lever to release the base with ease.

Low Profile
So that the iBase 2.0 can be installed and removed without tools, it has a central screw design. Such designs are normally relatively high, but Duotone’s engineers found a way to make the iBase 2.0 the lowest base of its kind.

2 Phase Washer Plate
The exclusive washer plate is made in a 2-phase over-moulding process (like an electric toothbrush). The upper side is a low-friction PVC material that reduces the force needed to tighten the iBase 2.0 onto the board, and the bottom side is over-moulded with a special rubber mixture to stop any sliding on the board.

2 Year Unconditional Warranty
None of these additional features add weight or sacrifice durability, so Duotone offers a 2 year unlimited warranty (after online registration) – something no other base offers.
