Any question answered...

Surely if you're concerned about what might happen if things go wrong - and why get insurance if you're not - then you'd have a brake anyway?

Yep. But I had already completely disassembled the bike and put it in bin bags. Spending today putting it all back together. On the positive side, I've finally cleaned everything.

£30 is good if you're willing to pay it and set it up in advance. Next time I will buy a proper cycle bag. And not try to do it on a fixed that really isn't set up for that kind of riding. :^

I did London/Paris fixed this easter too. And took the eurostar back. What route did you take?

A colleague of mine told me today that insurance companies won't cover bikes without a break? Anyone heard of this before?

Well it makes sense that they only pay out if your bike actually breaks somewhere.

Sorry, I meant theft insurance.

What size would people peg this as?


Chap selling it reckons it's a 58cm, which I am not sure I agree with.

Could be 58cm ctt

Good point. I've asked the chap for measurements anyway.

these guys are good and in the area but I think £30 is probably too low an expectation for a wheel build. All the best.

Thanks!

Hmm:

Hi N***,

So from the seat tube to the bottom centre bracket 26inch
From the seat post to front head tube 26inch also.

Hope these are the measurment you require.

Cheers,

Nonsense. Shame on them

I know it sounds like that, but it's actually spelt imbecile

How large and/or protuberant would my ears have to be in order to have an impact on my overall aerodynamic efficiency?

Positive or negative impact?

Either, just interested in general.

I resemble a dashingly handsome FA cup, in certain lights.

I would say it has the same proportions as this, for example look at the distance between the top tube and down tube at the head tube
This is 57.5 cms centre to centre
Look also at Eyebrows pro, the gap between the same tubes is noticeably less. The only problem with the one on ebay is the gash colour. And wtf is going on with the steerer?

Target:acquired

Also, the eBay seller reckons his Quantum is CF, which I don't think is true.

So, a potential purchase fraught with potential disaster.

And it's in Cheshire.

Hah!
If a 10 kph breeze can move them, consider them impactual.

Wanders off in search of hair dryer and anemometer

Frame is alloy, forks are carbon with alloy steerer.
One of the problems with that paint, and the white silver, is the propensity to fall off, really notorious for it.
There is another that colour on ebay at the minute where the paint has already started coming off.

I’ve experienced this a few times with my steel frame. I’ve tried many different preventative measures (normal grease, copper slip, anti-seize grease and carbon assembly stuff) and they’ve all failed (although it’s more me that’s failed in that I don’t move it enough). That said I usually clean the bike every month so it’s managing to seized up quickly.

I’ve looked at these two threads about using a carbon seatpost in a steel frame:

http://www.lfgss.com/thread53913.html
http://www.lfgss.com/thread35410.html

and I was surprised to see seizing was still an option. Question is will a carbon seatpost seize as often as an alu one? And if it does would a steel on steel seatpost mean there was little/no galvanic potential and would not seize. Do steel seatposts exist? A quick Google search suggests not but I may be searching for the wrong thing.

Basically short of just using my alu frame or paying more attention is there anything I can do to stop this happening again?

Firstly, why are you worried?

Second, to date the 3 carbon seatposts I have had in steel frames have not seized. I have used carbon assembly paste in all. None have been in there for years though.

I'm worried whether getting an alu post out of a steel frame is easier than a carbon one (i.e would you be able to use the heating up the frame method to get a carbon one out as you can an alu one).

Aluminium seatposts seize in steel frames because of corrosion (electrolysis and all that).

That should not happen with carbon, as the carbon & epoxy is relatively inert.

It may seize due to physical reactions (if the epoxy swells, for example).

In any case, getting a stuck carbon seatpost out would be a piece of piss - A hammer and chisel would make short work of it.

Indeed, though Alu seatposts can seize in carbon frames, and that really is a fucking pain to shift.

A nice polar solvent ie NMP would swell the epoxy, and make it soft enough to prise out.

Messy though.

Luckily if you fit the post with a nice layer of carbon assembly paste. It'll both slip and seize less.

Thanks all - unless someone says different it looks like a crabon fiber seatpost it is!
