Bike built from new parts is now 5 months old and have just had to replace headset lower (Cane Creek 40), BB (SRAM GXP Team) and lower pivot bearings (6000 2RS unbranded). For the former two items, I’ve not replaced bearings, instead I’ve bought entire new Hope headset and BB (having lost all faith in Cane Creek/SRAM). Obviously should have paid for Hope in first place (by cheap by twice etc..)
All 3 sets of bearings were way beyond serviceable. I’d already removed bearing seals, cleaned up, inserted new grease etc… but that didn’t last long. Most riding has been dry-ish, and never used anything like a jet-wash and never had issues like this on all the other bikes.
The failed bearings weren’t particularly corroded inside, e.g. no brown rust. The drive-side BB bearing had completely seized up – I couldn’t even turn it using a chisel and hammer (crank axle had been spinning round on plastic top-hat seal all this time !). Same with pivot bearings – feel like they’ve got square ball bearings inside. And headset lower bearing inner race had completely pitted up, despite plenty of grease.
Cane Creek 40 isn’t exactly cheap rubbish…or so I thought.
Lower pivot bearings use a steel 10mm OD thru-axle, and very sturdy, and all other pivot bearings are perfect still. So not exactly something you expect to fail quickly.
SRAM BB….well, I didn’t expect much given the bad reputation, but for the bearing to complete fail just due to load (and not rust) is very poor.
Suppliers of all parts all state that warranty doesn’t cover such items…
Am I just unlucky, or can certain bearings really not last half a year. I’m ‘only’ 73kg btw….
I’m well aware that expensive stuff will last (I’ve got 240s hubs, CK headsets etc.. and they’re like new after many years). But I didn’t realise how crap cheaper stuff could be.
rant over 😉
