Hello all
Quick one (I hope) I could do with replacing the bearings in my Roval hub.
A strip down (but not yet removed) reveals the bearing code 6903 LBLU, which I think have different seals on the 2 sides (black for inboard, orange for outboard).
Not seeing many of these coming up on Ebay/Amazon searches.
Now I could palm the job off on the LBS and make it their problem but I'm wondering if the 6903 2RS is a good substitute? I will take sealing over ultra performance any day of the week and I'm pretty sure my Hope hubs (similar construction) are 2RS type bearings.
If anyone's done one of these hubs and wants to tell me if it's a pig/easy job and any must have tools that would be handy too. Bearings in the cassette body look like they might be a bit tricksy.
Many hubs are labelled roval. Which bike do you have ?
Which variant of Roval wheels? The CLX road ones for example use Cermaic Speed bearings.
If it’s a DT based internal one then you might need the ring drive tool to replace the freehub bearings.
Be careful as the bearings might be angular contact. sounds like you have the same bearings in your roval hub as mine, haven't established if they're radial or angular contact.
Any shoulders on the axle or a tube spacer between the bearings? If there's no provision to support side loading on the bearings, and they're two different seal colours I'm betting they're angular contact.
Hi guys.
It's the fairly basic wide, alloy rimmed Roval wheelset that was on the 2015 Camber Evo. 142*12 rear.
The drive side bearing could be behind the ratchet ring and I wonder if that's the reference above to ring drive.
The two bearings in the freehub body are separated by a spacer. The others just sit on the axle which is constant diameter externally iirc.
Yes, you need to remove the ratchet ring to swap the freehub bearings.
Thanks and bother in equal measures.
Tool is £55. I might just drop this little job on the LBS after all.
Would anyone who's done this before be able to tell me if they need any particular presses or removal tools (eg pullers).
