Yes but they will be massively expensive. But that said you'll probably never need to replace them ever again.
You would need a ceramic equivalent for 2 off 6802-2RS (the actuall wheel bearings) and 2 off 6903-2RS + 1 off 6902-2RS for the freehub rotor if you want to do the full set.0 -
Cheers Dave, I'll have a Google using those part numbers you gave me and see what I come up with. I just hope they're not silly expensive.0

just looked on superstarcomponents and it adds up to £90.45 :shock: i would imagine they can be found cheaper though surely0

Stainless is the shrewd option.0

To be honest that sounds cheap for ceramic!!0 -
local bearing supplier is by far your best bet, you'll often be amazed at what they sell for in trade......0

Came across this place http://www.bearingshopuk.co.uk/ceramic-176-c.asp
They do the 6802s and 6902s for £5.95 each plus delivery. Thats £22.83 for three bearings delivered. Is this too goood to be true?0 -
sounds about right.
but for your first bearing buying experience i would pop the old ones out and then get down to a LOCAL bearing shop and have a chat.
or go down with the bearing numbers and have a chat."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

exactly as nick says! If you can take your old ones down to a local beraing supplier then you'll probably be shocked at the prices, they may seem too good to be true, but in reality they're not that expensive at all. Bearings really only start to get expensive on heavy duty applications or split roller bearings, neither of which are relevant to bikes.
Ceramic balls on steel races are very good, but fully ceramic is better. for those of you that have money to burn, and want only the finest, then a silicone carbide or silicone nitride full complement bearing (no internal cage for the balls) really is the best, make sure you get them with at least an RS (rubber shield). It'll cost a fortune but you'll never change them!
If there is enough demand for bearings then I might look into getting a bulk trade order, if people make a list of the common sizes required then I can provide some idea of costs etc.0 -
Thanks guys,
I'll do that.......... There's a bearing supplier not to far from where I live I'm gonna call in next week.
What's the minimum ABEC spec you would go for, ABEC 5? Is there any point in going with something that has a higher ABEC rating or would I just be wasting money?

ABEC 5 is the highest you should go, any more would be a waste as you'll enter the realms of prescision bearings. They'll do the job but you'll never tell the difference, remember that you're bouncing all over the show! That rating is for how round the balls are, and its massively precise at 5. Have a chat with the local supplier, and if it seems a little pricey, ask to see if its a trade price :shock:0
