bloody hubs
Another hub on the blink.
the supposedly bombproof Dt Swiss ratchet system.
Hub failure today. Only 150km ish on the hub. It wouldnt engage leaving me with a bit of a stroll / roll home.
On the bench at home you could hear it trying to engage and just catching a little.
Pulling it apart you can see damge to ratchet and re assembling it will engage on the bench ok
I can only summise that the admittedly minor looking damage started at some point during the cold weather, parts perhaps freezing in place And starting the damage. It then failed climbing the steep cobbles next to kinder res.
New ratchets needed and eye keeping on it

Re: bloody hubs
That's p1ss poor ... are the 'teeth' undercut at all?
May the bridges you burn light your way
Re: bloody hubs
undercut?
As in they effectively pull themselves together once they start to engage?
Yes. They are.
Once the edges are gone though...

Re: bloody hubs
Yeah, same as the dogs in a gearbox ... I thought that if they weren't already then it might help. However, seeing as they're already undercut that backs up my first comment about 'p1ss poor'undercut?

Re: bloody hubs
Uh huh. Better start taking spares on long rides. It's a 1 minute fix if you have the parts.
I've written to Dt to see what they say.

Re: bloody hubs
If you have done 150km it will be under warranty. Hopefully.
Too much power!!

Re: bloody hubs
You need to stop trying so hard Dave!!!! You're obviously putting too much effort in with your recent hub breakage record! You riding Wednesday?
Re: bloody hubs
manufacturing standards are dropping if you ask me.
Wednesday, hopefully. my cars in the garage just now but should have it back.

Re: bloody hubs
You've not broken the car as well have you! I've never had a problem with dt hubs, so hopefully
You've just been unlucky and it will get sorted out quickly.

Re: bloody hubs
Mostly been lucky with hubs, but had a new AC fail on me last summer, and a Hope on my old Marin seized a few years back after a year. In fact everybody I know who owned that model had the same problem - dodgy batch I expect.
Re: bloody hubs
I've had I think 2 or 3 freehubs go on me over the years.
1. cheap thing, running it well past it's best when I was young.
2. Shimano XT, due to it being frozen (and a bit worn really), flushed through with engine oil and continues to use for another 6 months..
3. I'm sure some other time.
Anyway, I think I tried to cable tie the cassette to the spokes - and it kinda worked for a tiny little bit.
But thinking of the consequences running out of drive in the middle of nowhere...I was trying to think of a "get me home" method. Then I remembered the disc mount sprocket.

Obviously you'll be fixed gear which is a right PITA when off-roading and you need to coast...but as a get me home it's about the only thing I can think of.

Re: bloody hubs
Are you thinking of carrying the cog and bolts and removing the disc rotor?
Flipping the wheel round?
Would the cassette miss the caliper? should do I would guess.
Or running a 135mm wide fork?

Re: bloody hubs
I imagine the chainline would need some adjustment, but there are plenty of people that are happy to ride fixie off road.

This sort of thing is a "good" example of what I had in mind when I posted this thread:Zippy wrote:But thinking of the consequences running out of drive in the middle of nowhere...I was trying to think of a "get me home" method. Then I remembered the disc mount sprocket.

Conceptual thought at the moment, haven't done any further work on this sir.
In my mind was thinking if freehub went, take wheel out, unbolt the disc, bolt on cog, flip wheel round 180 degrees and put back in bike. Like you said, cassette may be an issue, but can undo brake caliper and put out the way if the cassette does foul it.
Could store the cog on the outside of the disc I guess too - but I wouldn't.
Shouldn't need to bring extra bolts, bolts for the disc should be fine - braking forces I expect to be larger than the force my legs can produce.
