  • Inside diameter: 34mm
  • Outside diameter: 49.75mm, 20mm deep

Details

Reducers are a simple way to run a straight 1-1/8in fork and headset in a frame built for 1.5in. Each reducer presses into the head tube like a headset cup and gives a 1-1/8in bearing seat.

Fit and compatibility

It has a 34mm inside diameter and a 49.75mm outside diameter that presses 20mm into the head tube, with a 55mm lip. Check your head tube's inside diameter before ordering.

Fitting

A headset needs clean, correctly sized cups and the right preload once the stem is fitted. Our workshop can press it in and set it up for you.

Headset fit depends on the frame, so send us your frame model or cup measurements and we'll check it before you order.
