Any question answered...

At least the one in the picture still has enough steerer tube left to be used with one of my low stack headset covers 🤣

Cervelo sent out a brass shim to sort it. He claims it’s been fine

@specialist had a metal P3 with the shim, seemed to work. Rider weight is obviously a factor.

The chap I bought it from was, er, quite a big chap... So thats sort of reassuring that it wont slip, assuming that he wasn't lying through his teeth of course.

I read that article about the snapped steerers. Thats fairly worrying, but the steerer on my fork looks ok, no deep rusty bits. But after seeing that article, I think I'll be putting a new fork on it.
I now really regret selling an EC90 Aero fork that I hoarded for years.

That would imply some level of competence.

gov.uk website? They appear to combine incompetence and malice in a mixture never seen before outside the innermost circles of hell. If the M25 is the work.of the devil (hat tip to Good Omens) the gov.uk dev team is Satan's crack squad in action.

Condensed for clarity

I already measured it and the difference ist about 0.5 mm.
Also put a shim under the rotor for good measure to rule out any possibility of bottoming out.

I'll stop spamming the thread now. Thanks for all the answers and suggestions.
In case that I'm able to solve the issue, I'll report back.

It’s frustrating that we can’t get to the bottom of it :(

My final suggestions: loosen the Quick release axle then do it back up, but to the point it only takes light pressure to push the lever up but still clamps the wheel in the fork.
Check if the issue gets worse with the quick release fairly loose. Then go to the other end of the spectrum, try get the quick release clamped as tightly as you can and see if the issue goes away.

The only other thing I can think of is checking that the brake is actually operating at its full potential. Is it a hydraulic brake?
Are you sure that it’s properly bled and has full power?
Can you lock the front wheel from a moderate speed into an endo/stoppie?

Have you tried switching the Rotors around? If you put the rear rotor in the front, does the issue persist?

Which end of this component connects to the battery and which leg on the LED does the other end connect to?

Longer leg is positive, resistor normally goes on that one.

Anode is the proper name for the long one, cathode is the shorter one.

The resistor doesn't care which way round it goes, or which side of the LED.

And does it matter if the resistor connects to the positive or negative terminal of the battery?

Noticed a crack in the headset cup of my tandem. its threaded 1 1/4” which seems pretty hard to get hold of.. Anyone know of a supplier?

It matters only insofar as it has to make the LED polarity correct. Each of these circuits is equally valid

Have you tried

https://www.sjscycles.co.uk/

They are usually pretty good for harder to get components

Thanks, they don’t seem to have any 1 1/4 headsets listed. Maybe I’ll try email if I can’t find anything elsewhere !

threaded 1 1/4

is this any use?

Avanti West Coast - anyone taken a bike on their trains recently?

Last I looked Deore Xt 1 1/4" headsets were available NOS. Can't seem to Google my way to one now though. I'll have a look through my bookmarks later.

How do I post a gif? Can’t find info or figure it out 🤔

The same as posting any other picture, either link to it with the appropriate code, the little picture at the top of the text entry box does the hard work, or upload it directly to the site with the "upload a file" but below the box.

If I want to check what the OLN is on a frame for a new back wheel, do I just measure the distance between the dropouts? I've no idea what the old (now defunct) wheel is.

How many gears did the old wheel have?

do I just measure the distance between the dropouts?

Yeah, measure it, discover that it's halfway between two valid numbers, try to guess which way it's sprung 🤔

Ha! Actaully, the new wheel I had been looking at was adjustable between 130mm and 120mm which might prove useful if that is the case...

@PhilDAS One. It was a fixed/free flip flop hub.
