Well maybe I was just unlucky, but the bearings in the front hub of my new wheelset started to disintegrate during my sunday ride, re-enforcing my reputation as the hub killer.
Shimano Ultegra 0 Ed holland 1
I dismantled the hub to find some destinctly non-spherical ball bearings on one side. There was still grease present, in pretty good shape apart from some debris from the break-up. Fortunately the cups and cones had survived without damage, so I think the problem was caught as early as possible. I re-assembled, taking care to allow play for the axle compression caused by the quick release and everything seems smooth. A lucky escape.
This was rather disappointing, since I have only had the wheels for about 5 months, in that time putting a couple of thousand miles on them. I'd had very bad luck with Sora hubs in the past and was hoping that moving to Ultegra would give a significant improvement in reliability. Perhaps it this was just a freak bearing failure?
I would be interested to here if anyone else has had difficulties in this vein.
Cartridge bearing hubs seem to be the way to go - I have a "posh" wheelset with Hope road hubs - absolutely fantastic, but these are no longer manufactured. I have another a set of wheels built using Deore MTB hubs (fairly conventional cup and cone technology) and these have run many trouble free miles by comparison to the Ultegra and were clean & smooth at the last service. Can anyone suggest good hubs, based on experience, that will stand up to every-day use.
Sorry for the long posting, I'd be grateful for any input.
Cheers,
Ed
