Replacement Bearings
19 Jan 2017
Can replacement bearings be purchased for these headsets?

These headsets are NOS so unfortunately due to their age all of the original spares like the bearings have long been discontinued so are no longer available.

Shimano Dura Ace Hp 7410 Headset
15 Sep 2016
Looking to purchase above but unsure if it will fit my bike. The head Tube diameter that it has to go into is 30 mm. The threads are 1". Will it fit?

30mm is the standard size for the internal measurements of head tubes for 1" forks so most headsets including this one should fit absolutely fine.

How Tight The Upper Head Cone Housing
27 Oct 2014
As it is a cartridge bearing am I right to assume there is no adjustment to make between the cartridge and the upper head cone housing? How tight must be the later be?

There is adjustment required, it is not quite the same as with a loose ball bearing headset but it still requires proper adjustment or the fork steerer tube will remain loose. We do not have a torque value or anything like that but it needs to be reasonably tight without putting too much pressure on the bearings. It is normally adjusted by feel, if the forks turn smoothly and nothing is loose then it is perfect.
