The 40 Crown Race 52/30 is a replacement steel crown race from Cane Creek's 40-Series headset range. It pairs a 52mm lower bearing with a 30mm crown race seat, so it's the part you need when running a straight 1-1/8" steerer fork in a frame with a 1.5" lower cup.

It's a simple, hard-wearing part - handy to keep in the workshop if you're swapping forks between bikes, or if your original race has seen better days.
