Has anyone had a successful Shimano hollowtech BB warranty claim? my SLX BB is totally knackered after 5 months use and i plan make a claim under warranty. Has anyone tried anything similar for a shimano hollowtech and what was the outcome?

I though it best to check before i poetntialy throw good money after bad posting the knackered BB off!

you’ve got no chance.

Mate, I have never had a successful warranty claim on anything off any of my bikes!

What jam bo said.

It’s not faulty is it? You’ve just worn it out – it is a poor design though – even Superstar are better. But that isn’t a warranty issue.

thanks for the advice, whilst it is good advice it only spurs me on further. Ive got a long history of suprious warranty claims and i’ve never been unsuccessful yet.

I dont quite know why i asked the question.

I can’t see you having a snowballs chance in hell, it’d be like trying to get the windscreen wipers warrantied on your car, they might be rubbish but they are a perishable item, and in 5 months you could have done lejog 5 times for all they know.

Do you mean “spurious”? As in false or fake?

Well, if you compare to a similar item, say my oldest XT square taper on its third bike and over 10 years old, you could go with ‘unfit for purpose’.

I’ve had a new chain under warranty before now. With this in mind, surely they can be culpable for a defective BB?

Its a £15 part its not worth your time and effort. Hope you faced your BB shell, before installing it… without that you haven’t got a chance.

You’ve had 5 months of use out of it, so what’s the problem? It’s an item that wears out. Do you claim when your tyres are worn as well?
I used to get a year at most out of XT square taper bottom brackets. I never understand why people always talk about how great they were.

Superstar are better.

Have you jetwashed it and be honest, I remember a guy complaining about a bb and after repeatededly claiming he had never used a jetwash on his bike admitted to frequently jetwashing it when we found the bb to be full of water and totally banjaxed.

Its a £15 part

– I thought it was more a £37 rrp.

Can see both sides. It is a consumable part but not (imo) in the same regard as a set of pads or a tyre. A part that needs reasonable levels of stripping down to replace and comes with a year’s warranty. I would think that it should be reasonable to expect a little more but we seem to accept this level of engineering.

On the other side as said above, this is a component that can be expected to be renewed after a certain number of miles and this can be significantly shortened depending on the conditions you ride in and potential misuse (use of a jet wash pointed directly at the seals or installed in an unfaced frame). How does a consumer prove this?

I must be very lucky as my hollowtech BB is in its second bike, is about 4 years old and still absolutely fine. Must have done a good few thousand miles on it by now.

What’s this “jetwash” you mention?

Apart from the ocassional gentle ride all ive done for the last 5 months is follow the correct maintenance regime as recommended by the manufacturer.

5 months isn’t a reasonable life span for a non-perishable component designed for the purpose for which it has been used.

In terms of forseeability its too remote a loss for me to have anticipated.

Expect to see a new SLX BB in the for sale forum shortly.

£12.90 at rosebikes no one pays rrp

Depends on how often you ride your bikes, and in what condition.

My shimano BB has lasted 2yrs so far, and it’s still smooth.

I would have thought you will have to show that the 5 months is an unreasonably short life and that it is a design fault. IMO both are true but showing this is difficult and also that you have had a some use of the part so only a partial refund needed under SOGA

Worth a try if you like a fight. Me I have better things to do with my time

Its a £15 part its not worth your time and effort.

+1 – Its a consumable.

And if you shop in Germany, you can get HT2 BBs for less than a tenner

Like?

“Apart from the ocassional gentle ride all ive done for the last 5 months is follow the correct maintenance regime as recommended by the manufacturer”

Which is?

Was your BB shell faced before you installed it?

About a year from my experience for the XT/SLX, but that was with some serious jet washing which i’ve now stopped 😳

Still, at approx £12 form Rose, i’d rather pay that, than a larger whack up front for a Hope BB.

Get your tyres and brake pads done at the same time 😐
