Cane Creek 40-Series Steel Crown Race – 1.5

If you're building up a bike with a tapered fork and need to fit it to a headset, this Cane Creek crown race is the piece you're looking for.

It's the 40-series steel version, part number BAA0009S.

This specific race is designed to convert a 1.5-inch steerer tube down to accept a 1-1/8-inch crown race.

It's a crucial little part that sits at the base of the steerer tube and lets the headset bearings do their job.

It's made of steel, so it's durable and will last.

It's brand new, still in the package from Cane Creek.

If you're building a custom fork and headset combo, double-check your measurements, but this is the standard part for many conversions.
