Hope/Chris king Bottom brackets .. worth the money??
My Shimano ones have lasted longer than my Hope did. Cost of Hope bearings means you’re almost as well to get a complete new Shimano one anyway. Chris King apparently use surgical steel, so no matter how rough they get you can clean them up and regrease and pop them back in.Posted 4 years agothisisnotaspoonMember
I had a 2nd hand king one which lasted 2 years, it only died when I drifted the cranks out with a rubber mallet and the inner race of the drive side came out with them scattering the balls across the garage 🙁
They were bone dry, so the sealing isn’t upto much (there isn’t much), but there was no grit and the bearings were still smooth. On that basis I’d buy another for a winter bike/singlespeed/commuter (which is where it was) but I’d get the greasing tool as well. Having said that I’m not sure how much help it would have been!Posted 4 years agosomafunkSubscriber
If water gets down your seat tube and collects in your BB shell then any expensive/aftermarket BB will eventually wear and feel gritty, either take your seatpost out after wet rides or over zealous washing and tip the bike upside down to drain the seat tube and evaporate the moisture or drill a 4-5mm hole in your BB shell to let the water out.Posted 4 years ago
So pretty much what we can deduce from all this is –
Some people like them, Some don’t.
Some people think they last well, some don’t.
Some people think they’re good value, some don’t.
I guess from that, buy what you want at the end of the day, personally I’ve had better results with Hope brackets than Shimano or Sram.Posted 4 years agobigyinnMember
I’ve had an XT one which is on its third year. Its a little grumbly on one side but it still rotates.Posted 4 years ago
I’ve just obtained a secondhand Hope BB so I’ll be trying that out, too early to comment thus far. Certainly it was a little rough, but a good clean out has restored its smoothness.
The key to HT11 is going easy on the bearing preload, regreasing the bearings when they get rough.
Cheap bearings in reused cups seem to corrode pretty easily, so avoid.
The only thing I haven’t yet done is put a decent quality (SKF / INA / FAG etc) SS bearings in my superstar cups. That’s something I may do in the future, but no rush as I’ve got a brand new XT BB in the spares box at the moment.
It seems different riders get different results.
But – that just shows you that water down the seat tube / over tightening them makes them them die fast.
For £13 Deore ones, fitted properly and some care with water down the seat tube makes it difficult to justify anything else.Posted 4 years agoahwilesSubscriber
shimano BB’s DO have a seal, it’s a light-contact jobbie that relies on correct, careful installation.
even then, it’s not as good as others*:
hope BB’s are very good, but £72, i’ve got one.
gusset ext24’s are good enough, with even better sealing/shielding that the hope, and you can get them for £24, i’ve got one of these.
uberbike are similar (perhaps a little nicer* than the gusset?), i don’t have one, but will probably buy when i next need a new BB (with 6 or so bikes in the cellar, it’s only a matter of time)Posted 4 years agoNorthwindSubscriber
Hope seem very resistant to overtightening, Shimano seem pretty easy to damage with overtightening. And mountain bikers overtighten absolutely everything then blame the components when they break 😉
Just comes down to numbers for me- Hope cost 4-5 times as much as XT, and it’s an upfront cost. There’s a labour saving but changing a BB takes minutes so it’s not a big consideration. There’s an increased chance of falling foul of incompatability (since you care less if your relatively disposable Shimano BB doesn’t fit a new frame). So realistically, Hope has to last 5 or 6 times longer than XT to be a good alternative, and they don’t.
If the maintenance side bothers you (or you can’t fit them yourself) then things change, also you might just not like sending bits to landfill prematurely.
Middle ground is the EXT24 from Gusset, and its ilk- as servicable as Hope, not quite as durable, but 2/5ths the pricePosted 4 years ago
Overtightening is an issue – Ive seen riding mates who upon hearing a squeak go round their bike and tighten up everything as much as they can.
Then wonder in amazement when the bolt head snaps off, or wont hold tight for long.
A lack of simple understanding of mechanical things is often to blame for stuff wearing out fast or breaking.Posted 4 years ago
