Deda Carbon Blast Clip-On Extensions

The Deda Carbon Blast Clip-On Extensions are built for riders who want an aero position on drop bars — not a dedicated TT setup. Standard extensions are dimensioned for a full time trial position: arms stretched far forward, rider low and long. On drop bars, your contact points sit farther back, which means standard extension length puts your hands too far out. These clip-ons are sized to match the geometry of a road position, so you can tuck without compromising handling or comfort.

At 135mm long, the carbon extensions keep your hands close and controlled. The clamp-to-tip rise is 34mm, and the ITU and UCI-legal bridge sets the bars 90mm apart — a measured position that suits criterium racing and road time trials alike. The 31.7mm clamps are designed to accommodate standard drop bar diameters, and integrated armrests with dense padding sit atop the extensions to support your forearms without bulk. Total weight comes in at 226g.
