Shimano 105 Rear Hub Query

Secteur

http://www.evanscycles.com/products/shi ... ear%20hubs

How do I know if it's the "36 Hole" or the "32 Hole" version I need (what does this mean?)

Also, how do you get the spokes off the old one and onto this new one?

Can you not just buy the internal part that contains the bearings etc? (sorry dont know what it's called)


Reason: despite having only done 1000 miles, I can hear the bearings grinding - due, I think, to my over-zealous cleaning with degreasers / chain cleaning spray.

You can buy spares. Strip the hub down. Inspect ball bearings, cones and, races for wear/pitting. Replace worn parts. Ball bearings are cheap and easy to get hold of (1/4" is the size. 18 are needed).Cones are also available. Repack with waterproof grease and adjust cones.

Sorry - to clarify, these are apparently sealed hubs - they can't be stripped down

EDIT - the ones currently on my bike are sealed hubs - I dont know if they are 105 hubs, it says shimano on the cassette and it's a full 105 groupset bike.

Are you sure they are fully sealed? It's likely that either (a) the have a rubber weather seal, which protects cone & cup bearings (see advice above), or (b) they use press fit bearings which can be drifted out and replaced for a few quid wit shny new ones.

If you aren't site, either bung a photo up here and we'll be glad to tell you, or amble over t your LBS.

OK cheers - will sort a photo.

According to the bike spec, this is my hub (no manufacturer given, and none marked on the hub);

"Rear Hub: Forged alloy, sealed, 32h, for J bend round spokes"

36/32 id the number of spokes.

you can buy the hub and swap all the internals over if you want.

But TBBH just give yours a clean and service. bearings are available separately for any Cone and cup hub.

From the spec site;

"Rims: Mavic CXP-22 S, aluminium triple-wall, sleeve joint, CNC machined sidewalls, w/ eyelets"

count the number of spokes in your wheel, thats how many holes the hub needs. if youve never built a wheel and arent pretty handy dont try it. maybe £25 30 quid to have one built.
its quite do-able but that said there are many pit falls.
