"We have a range of adapter plates for the most popular Tri and TT bikes, but for those models we don’t cover, this universal adapter will fit. Replaces the elbow cup and extension bar brackets on Tri bikes that have mono risers or twin stack systems. Reduces cockpit clutter and simplifies aero bar installation. You drill the bolt holes to suit your mono riser/twin stack bolt spacing, so it will always fit perfectly. Features a pre-threaded BTA mount for a bottle cage or top-mount hydration system. CNC precision machined from aluminium for maximum strength and a superb anodised finish
 
NOTE: this adapter is NOT UCI compliant."
