Vision TriMax Carbon Reversible Extensions

The reversible design allows you to flip the extensions to change the angle and hand position of the J-bend. This gives you two distinct ergonomic options to better match your wrist angle and reach preferences without needing to buy a different set of bars.

While these extensions are specifically optimized for electronic shifting systems like Shimano Di2, they can accommodate mechanical cables if you are careful with the routing. However, the internal routing is designed primarily for the clean exit of electronic wires.

Yes, these extensions do not come with armrests included. They are designed to be compatible with most standard clip-on systems, so you can pair them with the armrests that best suit your existing cockpit setup.

The internal routing features a rear exit, which is generally straightforward to manage. Because the carbon construction is stiff, you will want to use a cable guide or magnet tool to help pull the wires through the internal channels efficiently.

The 385mm length is the total length of the extensions. While they offer quick adjustment for positioning, you may need to cut the carbon extensions to your specific length requirements if they are too long for your fit.
