Zero Stack 41/30 Headset Bottom Cup / Bearing

[Wannabe]

I'm looking for the above headset cup/bearing to get my Gravel Grinder / Hybrid bike turning properly.

I do not have have R800 to pay for a Hope or similar top of the range item.

Contact Evobikes.

The cheaper ones are usually only available in a complete headset assembly so you would probably have to buy the complete one.

For the bottom cup that I wanted for my Cannondale the Hope one was R900 for only the cup, excluding race or bearing.

My bad, Guys.

After some more precise measuring of my headset cups (using a vernier), it transpired I need a ZS41/30 cup/bearing. These seems to be more readily available.

Must add for more clarity, this is for a 1 1/8th Straight steerer fork. (rigid fork on my hybrid bike)

Been to Janos, they do not have in stock what I need.

I still think I'll have what you need.

PM sent.

Thanks Robert.

Received the package this morning, fitted it (after a bit of a pow-wow with Robert) and most of the flex/movement is now gone. There is still a bit of flex, but I suspect that could be from the Shimano cup 'n cone hubs that will need a bit of fine tuning. (if I grab the fork and try and move it backwards and forwards, there is no flex. With the wheel fitted, there is some flex. When I grab and hold the wheel firm whilst rocking, there is no flex, therefore my presumption that it could be the hubs that's the culprits now) Hope my ramblings makes sense. ☺️

 

[RobertWhitehead]

It does yes, I do have cones for Shimano hubs as well.

You may also feel some "rocking" from the brake action. 

To check the cup and cone bearing play hold one fork leg with one hand and the tyre/rim with the other and feel for lateral play.

[Wannabe]

David, I did check it the same time, and there was lateral play.

Will take some time tomorrow to try and fine tune it a bit more. (spent about an hour on it a few weeks back)

Can't wait till I can upgrade to proper wheels with sealed bearings, so over this Shimano crap.
