Internal steerer tube diameter
18 Jun 2018
Hello, what’s the maximum internal diameter steerer tube this will work with?

This item has a diameter of 23mm & is for use with 1 1/4 inch carbon steerers only. I hope this helps.

Kind Regards

Hi Guys:

Wondering if you carry:

Shimano PRO Headset Expansion Nut for Carbon Steerer Tubes 1 1/4 Inch "but 50mm" length not 25mm like online
Part # PRHS0081

Let me know thanks! and cost.


Unfortunately we only carry the 25mm version as this is all that is available from Shimano's UK distributor so we would also not be able to order the longer version in either for you I'm afraid.
