Any question answered...

Lidl and Aldi are also good for picking up general fastenings, hooks etc.

It's the more random sizes that don't tend to come in those boxes of screws that I need to stock up on. Mainly longer screws, tamper proof ones and the like.

Does anyone have a suggestion for a weekend getaway within reasonable driving distance from nw london? Wife’s 8 months pregnant and we would really just like to spend a night somewhere thats not our house, so a nice B&B somewhere in the countryside.

Cotswolds - 75 miles, reasonably easy drive, some nice countryside.

What's a wall rocket?

A type of wild rocket (the edible plant) that likes to grow in nooks in walls

Cheers, that's the kind of thing I was looking for. Will order a selection from there

snot rockets ofc

Anyone got a good quality 1" threaded headset knocking about? shimano 105 type etc. 26.4mm crown race please. Based in north london but heading south briefly later.

What mm/gauge(?) of rebar do I need for 2m metal tall "canes" to secure plants?

¼—½m will sit in the ground.

Cheers

I would go with 12mm, anything much less is liable to bend if you hit a brick or whatever as you're whacking it in. You probably know, but it comes in 3m lengths.

How do you go about looking for a new saddle? I've never had anything other than what came as stock so I don't know any different and i've never had any problems but I just want to change it because bikes.

Buy used on here? Try out a few? Don't bother?

There are a few main different shapes depending on if they have curve front to back, side to side, or both. There's no real way of knowing if you get on with one type until you try it, be it from buying and returning from a shop, borrowing from friends or doing a saddle fitting at somewhere like Condor or Cadence.

Once you've found what shape roughly works best for you then you can guess which fancy new saddle will work best. For example I like ones that curve front to back but are flat side to side, I used a Romin for a long time so when looking for a new one I went with the Fabric Line Shallow and it feels very similar.

Another broken saddle clamp bolt.
This time it isn't so easily replaceable.
Bolt resembles an M5 but not the standard M5 thread, possibly finer.
It has bamboozled Orbital Fasteners of Rickmansworth.

#10-32 UNF, 3/16×32TPI BSC, 3/16×32TPI BSF-Whitworth, 2BA
The first should only be found on US manufactured product, the others are candidates if the product is very old and British. An actual fine thread ISO M5 is the least likely, and once you go down that rabbit hole you're into a choice of almost any thread pitch according to the predilections of the engineer who specified it.

Rebar or studding?
You could even treat yourself to galvanised or stainless studding.

Stainless is 6 times the price of rebar, go directly to the LFGSS Golf Club, do not pass 'Go', or a Range Rover dealership.

12mm, anything much less is liable to bend if you hit a brick

If you hit anything stout enough to bend #3(US)/#10(Metric)/⅜"/9.5mm rebar, you'd be better off moving to one side of it than trying to plough through it with #4

Stating the bleeding obvious. The point being that a lighter bar could bend BEFORE you manoeuvre it around the obstruction if you are giving it a good clout,12mm won't.

If you don't notice you're hitting an immovable object before you bend a #3 rebar, then I'm definitely not letting you wrench on any of my bikes 🙂

Thank you for the reply.
It is a BBB aluminium seat post that, I believe, was standard on this
'Team C' carbon Boardman, so shouldn't be 'very old'.

I'm currently trying to emerge from the rabbit hole of near-Ruislip bike shops.
The least useful answer so far, inevitably is from the Ruislip High Street Specialized Concept store where I was told that they didn't have anything 'that looks like that'.
('That' being the other intact bolt).
I asked whether they had any bolts that could give the same function, but of course not.
And, of course, they do not stock any 31.6mm diameter seat posts.

In that case it's definitely a regular ISO coarse metric thread, and any fit issues are down to damage.

Cheers.

I didn't realise it came in 3m, but the closest seller to me on ebay cuts to the m for an acceptable price.

Saddle was changed maybe two months ago,
and,
I don't remember the bolts being particularly hard to loosen/tighten.
Would neglectful, (no grease), corrosion of the (barrel?) nut lead to such an amount of play?
A standard M5 bolt wobbles in the remaining thread.
