Our review

Unique amount of adjustment for extreme positions but heavy and droop-prone
Skip to view product specifications

Profile’s T4 Plus, the latest model in the highly popular and long-running T+ series, has a unique design that adds extra adjustability but extra mass too.


Separate arm rest and over-bar clamps are able to slide forwards and backwards independently along the ski-bend extensions, which have gear entry and exit slots. Deep, Lycra-wrapped pads are removable via two wrapover straps, which means none of the inevitable peeling off of stuck-on Velcro.

The pressed alloy plate F-19 arm rests are angle-adjustable but there are no height gain shims. The arm rest clamp bolts are hidden by the plates too; make sure they’re properly tight as they’re a right pain to secure if they start to droop, which has happened to us several times on test bikes.
