Deda IN-5 Headset

This fully integrated 1-1/8” - 1.5” taper headset is light and has a very low stack-height. The large 1.5” lower bearing, mated to our signature tapered carbon fork steerers, spreads riding forces and gives flex-free braking and instant response to steering input.

Integrated, 41.8ø upper, 51.8ø lower, for taper head tube. Both bearings are stainless-steel ‘ACB’, meaning ‘Angular Contact Bearings’. The head-tube seat angle is 45º.
