V2 High Rise 3D extensions are designed to work with Shimano Di2
electronic shifters and SRAM eTap CLICS. As such, High Rise 3D extensions
are free of mechanical cable entry ports.
DO NOT DRILL OR MODIFY extensions in the region
immediately in front of the extension clamp (high-stress area). Any such
modification immediately voids the product warranty. Sync Ergonomics
is not liable for product damage and/or personal injury resulting from
product modification.
The length/height of the extension (with shifters installed)
must not exceed the original length/height of the supplied extension.
Sync Ergonomics is not liable for product damage and/or personal injury
resulting from untrimmed extensions.
The correct length and height needs to be set for the athlete in question.
For riders seeking a UCI-compliant position, 100 mm is the maximum
allowable height. High Rise 3D extensions must be trimmed to achieve
this measurement, measured as the vertical distance from the centre of
the arm cup pad, to the top edge of the shifter body.
Please ensure you use a properly designed
tube cutting guide (e.g. Park Tools SG-6) and saw (e.g. 32 TPI hack saw
blade). Post cutting, a fine metal file or deburring tool will be required to
finish the tube ends.
