Did it work before?
If so have you done anything to it?
If you have, what?

Er, that's kind of odd. I can't fathom how it couldn't hold the saddle.
Is the saddle clamp all built up in the right order, with everything in the correct orientation?

cooldad

Can't have been that important.

sigorman85

The clamps that's hold to the sadle rails have worn some how seems like the metal is quite soft that grips the rails

cooldad

I don't believe it.

cooldad

On second thoughts, it is Crank Bros. Probably changed the grade of cheese.

YeehaaMcgee

can you supply pictures? I'm almost certain something's not aligned properly. I've crashed mine badly loads of times and even though the clamp is damaged in many ways, it still holds the saddle securely.

sigorman85

The clamps have some burs on them where it's griped the rails in guessing this is the problem every think is in the rite position where the clamps must be a soft metal it's created the burs causing it not to clamp properly..... I'd this sounds better the clamps that hold the rails on my sdg aliso are full done up but still there is a gap

Sorry for the typo's im on the Iphone

YeehaaMcgee

Can you file the burrs off?
The clamp is made of aluminium, as are a hell of a lot of saddle clamps, and aluminium is a fairly soft metal.
However, it shouldn't cause any major problems.

I didn't realise it was impossible to type on the iPhone.
Sounds like an useless device.

sigorman85

Is when you have had a few beers lol.... Yeah can file it and probly make some bodge job thing at work Gd job Im a Cnc miller but wanted some ideas so I can go for a ride tomorrow

sigorman85

Thing is if I file off the burs I'm loseing the material so it's still not going to hold the sadle guess iljust have to whack the old pole on and try to source some new clamps or make some

sigorman85

Basically this part and it's hard to find a new part

You're a cnc miller? Strange, machines usually struggle to ride bikes.
Just ask your lbs for a new clamp. Funnily enough I did exactly this yesterday, and they're ordering one in, nay bother, like.

sigorman85

You no what I mean ... So what's the site they are getting the part from?

cooldad

Bike shops get parts from distributers, not random websites generally. And it's 'know'. Believe it or not, words that are spelt differently often have different meanings. Which makes it easier for people to understand your random ramblings.

YeehaaMcgee

"burr" is one of those words that was very misleading in this context, since a burr is something you could have filed off.

cooldad

I believe that iPhones contain a secret chip that reduces the users IQ to mong level, to aid the Apple/Illuminati world conquest.
I, for one, welcome our shiny white overlords.

YeehaaMcgee

Is that because it will result in you being the cleverest man alive?

FTFY because I am an equal opportunity genius.
But glad you noticed.

sigorman85

cheers for the ideas of fixing the clamp the ride was brill

YeehaaMcgee

Did you manage to file it then?

sigorman85

nope i inserted somer rubber where the clamps are its working at the mo but im sure it will fail tomorrow. so im taking it to work to see what i can do. if no joy looks like i will have an exspensive paper weight

YeehaaMcgee

Or you could just buy a new clamp.

cooldad

Or just clean up the old one.

sigorman85

from?

cooldad

A shop. Probably a bike shop. One that sells Crank Bros stuff.

sigorman85

I can't find any where on the net for the part that I need it keeps coming up with forums talking about crank bros buying the design from maverick as the Joplin was a maverick speed ball

YeehaaMcgee

I'll type this in capitals since you seem to be repeatedly missing it.
LOCAL BIKE SHOP

An actual shop that sells the stuff. Phone them, visit them.
