This is a Geez tour shaft. The joint is Uni-Loc. The tip is around 12.0mm. This is based on the data at the time of ordering, as I don't have precise calipers. Please understand that there may be some variation. This is a full custom order. It's now quite difficult to order these domestically, making it a very rare shaft. * There is a name printed on the back of the logo. If you are concerned, you can sand it off or have a workshop remove it. Re-tapering is also possible, but it will be a paid service. It hasn't been used for very long, and the condition is very good. I got used to the carbon shaft I was using while waiting for this to be made, so it's a waste and a shame to keep this as a spare, so I'm putting it up for sale. Sets are available for sale. Price negotiation is possible. Please comment if you have any questions. Thank you.
