It's not just a vanity piece.
Oh no.
This is so much more than just a vanity piece.

It's a beautiful vanity piece handcrafted by an artisan. Can you not see the mug dangling in potentia? The instagram likes just waiting to be clicked?

Just wanted to show (with some back-of-the-envelope-typed-during-a-coffee-break sums) that you didn't need anything too crazy to sustain that kinda load.
Also worth noting that this is a classic plane-stress situation (ie very thin walls) so you only really have the axial load to consider. Would be interesting to see how much the load of the rider etc cancels with that of the internal pressure...

You need to calculate the hoop stress for the given pressure. This is the force balance between the walls (F=stress*t*L*2) and the projected area the pressure acts on, not the curved area (F=P*L*2*r).

I think you've quoted the ultimate tensile strength there (1.4 GPa) which would lead to true explosion-style failure. The yield stress would be a better target, you'd be able to ride the frame after that loading. For typical 4130 (Cro-moly) steel that's ~460MPa (ref) and gives a radius-thickness ratio of 15/460, or a wall thickness of ~0.46 mm for a 28.6 mm tube. Not dainty, but not a gas pipe by any stretch.

She's locked down her twitter feed now too

Found another one, just in case

Can't find it either, she says she deleted it. Any luck finding a copy?

Is that George Osborne who lets himself in at the beginning?

Old loyalty card works really nicely, a penny might be a bit thick.
Better pads also help. If they're salmon (ie wet weather) ones then they're gonna squeal a bit in the dry whatever.

Just buy value (ie not chinesium) spanners in the right size as you need. Much easier.
Don't bother with fancy grips, they just take up space!

If you were nearer (you're Edinburgh right?) I'd offer to lend you the one you need!

And now it works. How odd.

(unless you changed something you sly devil you)

Broken links aside, you will find that not all headsets are the same size. If you want a pin spanner then I actually would recommend the park one purely because the springiness of it keeps it in place slightly/allows for slightly different sizes.

Still broken. Try this one

ASO have made their move. http://www.cyclingnews.com/news/aso-try-to-block-chris-froome-from-racing-tour-de-france/

Needs some poo though...

Edit: too slow...

I think I have a bnib deore triple mech you can have for not much

Tandem stoker? Should have turned them off while on the move!
Nothing worse than having your eyes nuked by someone's light only to then be unable to see them until the next shockwave hits you...

Loctite 243 if you want liquid or 248 if you want a pritt-stick style thing.
@BernardRenault I also have a headset press available in NW10/SW7.

We have a Wild Country Hoolie 3 ETC that has turned out so well our friends copied us. Masses of space for the weight, great quality. Not so good (ie. impossible) if you can't use guys but flipside is easy pitching.

Edit: too slow

Came here to post this. Left pleased.

I have a set of these I'm going to swap out (not a fan of the smaller hoods) if anyone wants them
