Just a recieved a wheel in the post. Its second hand and unused. Condition indicates it really never has been used.
But the wheel bearing don't feel great. If I spin the wheel and hold the axle it has a slight notchy feels. A sort of slight increase in friction then release.
It won't be noticable once the wheels on but is this normal for new cartridge bearing? Will they bed in?
There will always be "stiction" in the seal, if that's what you mean.
As long as the bearing turns smoothly without roughness or play that's fine. If it is rough, it's no train smash; just remove the bearings and take them to a local bearing stockist for a match. Alternatively your Hope dealer can fit new without the butchery you will need to undertake.
Evo?
I've seen a pair returned to hope due to an incorrectly machined axles. Felt just like you describe.
notchy? Knackered bearings IMO
The bearings will be slow moving because of the seals but not notchy if they have never been used.
Oh I'm stuck now. There is a notchy ness beyond the seals dragging, you can feel a few positions where the axle is slightly keener to sit
But its obvious that the wheel has never been ridden
Thinking aloud
I paid 87 plus 10 for the wheel (hope hube and mavic 819) unused. It camewith an unused michelin wild gripper UST and an unused sram 990 11-32 cassette. I'll get something for the casette and tyre so even if i new bearings I don't feel I've done too badly. So at the moment I feel like seeing if a ride helps bed things in....
Stop worrying about it and just get riding. Those bearings are very robust though once water and mud get in they will wear fast. You can carry on riding with a fair bit of slack in the bearings, nothing's going to happen.
It's a bit like the old Land Rover doctrine on transmission noise: "Keep driving the vehicle until the noise becomes unbearable for the operator. At this point, consider an overhaul".
I agree with globalti, just ride the wheel till the bearing stops turning. Do you think you will notice a slight notchy feeling when riding on rough ground?!
I recently bought some new Hope bearings to rebuild my rear hub. Of the two main axle bearings one had no grease in and the other had very little.
IIRC the bearings site pretty flush with the outside of the hub so without removing them you could gently lever the outside seal off and check if there is any grease in there. Tip of a Stanley does the job nicely
I feel better already
Just ride it and then worry about bearings when I have areal problem with them, cheers
Might look at grease but use will mean that I can't dend them back and I need to stop wondering about that

You jammy dodger! You've had a right bang result and no mistake!
Just ride the flippin' thing. New bearings often have a slight 'gritchiness' IME, this soon goes after a couple of rides. And if it does go, then it's simple enough to swap the bearings over.
[s]as others have said, you got a bargain, you can easily lift the seals and regrease the outer bearings without dismantling the hub (just take end caps off), then ride it. Worst case scenario you need to pay a few quid for a new bearing (it'll only be one giving the notchy feel). [/s]
Its about to explode and it will kill you. I'll give you a tenner for it, for your own safety.
I would use a needle or a pin to leverage out the seals, a lot better than a blade!
I will try and do some kind of guide for greasing up bearings later on if I can find the time.
1) lift seal carefully with pin
2) add grease
3) replace seal
