Profile Design A2a / A2c TT Riser Kit

Adjust the stack of your Profile Design A2a / A2c cockpit with Dabrace™ kevlar polymer flat risers for its dual-tower, flat-handlebar setup. Choose from five heights between 10mm and 50mm. A separately selectable polymer BTA Cross Bridge is also available with a 135mm mounting-hole centre spacing, so you can order the bridge independently of your riser height.

How to Order Your Setup

Flat risers and the BTA Cross Bridge are separate purchase options. Select your required variant, add it to your cart, then repeat for any additional component.

• Flat Stack Risers: Choose 10mm, 20mm, 30mm, 40mm or 50mm.
• BTA Cross Bridge: Select the polymer 135mm option if required. Check your mounting-hole centre spacing before ordering.
• Cockpit Compatibility: Match the components to your installed Profile Design A2a or A2c cockpit, not the bike frame name alone.

A BTA Cross Bridge is not included when you select a flat riser height. The bridge option should not be treated as a complete BTA hydration mount.
