Any question answered...

Cheers guys for the leads on the foldaway bags. I don't think zip is important, I think he just wants a couple of these to put in his backpack for food shopping etc etc...

Will see my local co-op has some tomorrow, I don't remember seeing any in that store but maybe I just wasn't looking nearly hard enough.

So what is the solution? Two clamps seems excessive.

Might get him one of these for comical effect.

So what is the solution?

The solution to what? Making seat posts under nominal size is the solution to getting a proper fit when the seat tube bore might also be under nominal. There has to be a clearance when assembling, which is then closed by the clamp.

The solution to slipping might be one or more of the following:

1. Reduced load (lay off the pies)
   
2. Increased radial pressure (more hoop stress from a burlier clamp)
   
3. Higher coefficient of friction (friction modifiers like Tacx paste, eliminate slippery anodising as raw Al is stickier than Al₂O₃)
   
4. Double clamps. These have advantages which might not be immediately obvious. The clamping diameter on the post is smaller than the clamping diameter on the outside diameter of the seat tube, so greater radial pressure is developed for a give hoop stress in the clamp. The coefficient of friction between an aluminium clamp and an aluminium seat post is typically substantially higher than that between a steel or titanium seat tube and the same seat post.

Well, a pop rivet. I solved a slipping post issue with one of those by drilling through the post via the stress relief hole at the bottom of the seat tube slot and riveting the post in place. It does limit the adjustability a bit :)

1 never
2 the new clamp was meant to be burlier
3 could try carbon assembly paste
4 or could stick with the double clamp as is

Being fat and lazy it’s probably 4!

5 is possible

Correlating increase in security though.

Anyone used appliances direct before?

Thinking of buying a tv but found tesco direct somehow close down the other week so a bit stuck for places to shop.

Why you no assembly paste first?

I use assembly paste on a ti frame with a carbon post. The paste wears out quite often and needs replacing regularly so I don’t think of it as a permanent solution.

I've heard people sticking correct lengths of wood or pipe into seattubes to stop the post going further down. No good if you have Di2 in there but was an option for my old TT bike before I got the carbon paste onto it.

How often are you moving the seatpost? Mine was fit and forget.

Bought an induction hob from them for a good price. No issues at all.

My seatpost is moving because my arse is so heavy!

The ti frame/carbon post slips every few months. It’s the canyon leaf spring post, the flexy nature seems to grind down assembly paste.

theres a piece of software thats good for coding mathematical / geometric GIFs - cant remember what its called (example at the link below)

But I want to buy it next week when I finish painting the spare room.

How can I watch that new Sasha Baron Cohen thing? Is there a way around that Showtime malarkey?

Isn't it being broadcast on C4 in the UK?

Ah, it's on at 10. Gotcha.

I keep getting spammed by my energy provider to say they are in the area and want to install smart meters for my gas and electricity. Should I say yes? Getting annoying now.

Kinda ties you into that supplier, no?
