Custom built wheels - Cvhorus or Record hubs?(4 posts)

Custom built wheels - Cvhorus or Record hubs?altidude
Jan 19, 2003 6:51 AM
I have read several posts on various websites that Chorus hubs are superior to record hubs on custom built wheels because the record hubs use titanium pawls which have limited durability compared to Chorus's steel pawls, is this durability issue true or not? Also, some have said that the grease port on the record hubs is used to expel the old grease in the bearings while others have said it just a place to inject some oil 9not grease) on raceday, which is it and do the chorus hubs have a greaseport and if not is that an advantage or disadvantage compared with Record hubs?

The grease ports are for grease, not oil. This comes directly from the hubset instructions on the campy website. The greaseports are only on Record hubs.

I suppose the titanium pawls could be an issue. Hardened steel should last longer, but I've never read of anyone needing to replace the titanium pawls.

If you ride in the wet, maybe having the greaseports would be handy.

Thanks, that kind of confirmed what I was thinking. Some guys say the greaseports are useless, but they seem like a good idea if you don't have the time to do a complete breakdown. By the way, do the campy hubs used sealed cartridge bearings or are they non cartridge type?

The bearing balls are in cages, but the races are separate, not a cartridge type. Check out www.campagnolo.com. They have all the info. including overhaul instructions in pdf form.
