15 Degree Sliding Armrest Wedges / Shims


Our new sliding wedges allow you to achieve a comfortable armrest angle when adopting an upright forearm or Mantis TT position. Designed to accommodate fore aft Tribar Mount bolt fittings with a mounting range from ‘0’ up to 25mm using M5 bolts. As this design features one long slot as opposed to two holes it can allow the wedge to slide back and forth to allow fine tuning to the position of your armrest. The degree of movement will depend entirely upon your existing bolt mounting centres. Please check the image showing mounting parameters. These wedges will also work on smaller bolt centres when our regular type wedges don’t, accommodating frames such as the Cervelo P5 DiscBrake and the Shiv DiscBrake bikes as well as many others. (Note: Shiv stock armrest will require small hole adjustment)

CNC machined using 6082 T6 condition Aluminium alloy (anodised black), supplied with A2 Stainless Steel bolts delivering the highest quality product at just 17g per wedge (excluding bolts).

Lead time: Typical 1-10 days – Contact for availability.

Fitting Guide

Detailed Fitting Guide

Plasma Cockpit Wedges – Three Step Fitting Guide
Our simple wedge design can usually be fitted requiring only a 4mm Allen key tool and without
having to remove gear cables or wires as long as there is enough play to allow the addition of
the wedge and any adjustments in height desired. To maintain the same pad height you are
likely to need to remove 1x10mm spacer from the current stack height. Your current bolts
supplied at purchase are replaced with our height adjustment bolt pack which are in 10mm

Step 1

On one side remove the existing long stack bolts located beneath the carbon base bar to
release the Tribar extension mount. It may be easier to slide out the extension poles as they
will become loose but the bars can be held in place. If no adjustment to the stack height is
required then leave the brace plate between the left and right stack in place to help hold the
stack stable. If height adjustment is required then both stacks will be altered together during
this step.

Step 2

Bolt the ‘Plasma Cockpit Wedge’ directly onto the base of the Tribar mount using the bolts
supplied. These bolts require the use of the small M5 (Black) Spring washers supplied.

Step 3

Bolt the Tribar mount & wedge combination back onto the stack using the appropriate length
bolts supplied. Note that the assorted bolts increase in length by 10mm increments and that the
longest bolt that can be fitted without reaching the top of the wedge should be selected. The
front bolt should be 10mm longer than the rear bolt. These bolts require the use of the regular
M5 (Silver) washers supplied. Remember that your extension poles should be in position before
tightening the stack bolts.

This completes the fitting of your wedges.
