Any question answered...

Is there no Piers Morgan is a cunt thread on here? It would surprise me if there wasn’t, but maybe Google is currently overrun with searches along those lines!

That’s a bit like having a “we need oxygen to survive” thread.
Goes without saying really

Piers Morgan is a cunt

tautology innit

@PhilDAS @campervangogh LOL, completely true!

Plugging Di2 holes on my frame that aren't used anymore, anything more elegant than a carefully cut bit of electrical tape?

Assuming the holes are round - rubber grommets

My turbo wheel has an old (not sure which gen) 10sp ultegra freehub, but I want to use my road bike with 11sp 105 (I think 5800) on the turbo. What is the best way to do this?

I know I’ve done it before but it was a few years ago and I’ve forgotten. Presumably if I mismatch a 10sp cassette with an 11 derailleur, the spacing will be all wrong? I think what I did before was swap the 11sp cassette onto the 10sp freehub but there was some extra faff about removing a sprocket and adding/removing a spacer that I can’t remember?

presumably the turbo with the 10sp cassette on it will also have a spacer.

Remove the spacer and put a 11sp cassette on without a spacer. That should be all.

Older 10sp hubs can’t take 11sp cassettes. They didn’t need the additional spacer to accommodate a 10sp cassette.

11 speed MTB cassettes fit on 10 speed freehubs.

I have an Altec bonded cx frame with an Alan 1" fork.
The A2C is ~15mm too short, headtube slightly ovalized.

The options I can think of are:
a)wait indefinitely for a 1" canti Wound-up to turn up.
b)get Mielec to make a suitable fork.
c)machine and bond a lower headtube extension. Possibly with a stepped joint?
d)spacer between fork crown and crown race.
e)some combination of above?
f)sell it on and get an arkose.

I thought you could get around this by removing one of the sprockets from the 11sp cassette so that you would preserve the 11sp spacing but you’d just be missing a gear?

I just tried this and fitted it to the 10sp freehub without the spacer and I was at least able to tighten the locknut. I won’t have time to test ride before my turbo session tonight but I guess I just have to remember to avoid the 11t (don’t worry I’m not that strong anyway!).

Mtb (or ground down 11sp cassette) isn’t an option in this case because I want it sorted for tonight and hopefully it’ll only be for a few rides until I get my tt bike rebuilt.

Does this type of screw as used in an FSA Seatpost saddle rail clamp have a specific name and does anyone know where spares could be purchased?

Shimano do specific grommets for this. What size do you need as I have some spare, would happily post over.

It's called an "FSA Seatpost saddle rail clamp screw", and can be purchased from FSA, but probably only as part of a complete seatpost.

You might be able to hack a repair using a conventional screw with a matching pair of male and female spherical washers. These you can find in brake shoe kits.

What’s the best (economical, secure, reliable) option for acquiring 10 or so EAN? Paying £100 a year for a GS1 license and 990 spare EAN is pretty dear...

Helpful advice as always, I'll try giving that hack a go. Cheers

What is the statistically sound way to find out if the the length of projects are decreasing over time ?

The obvious one is to just take an average of all finished projects each month and see a change. But at the start of records it will be unstable and as you get to the present it will become more and more stable and harder to move the average.

Bin the projects by duration (quartiles, perhaps) and start period and do a chi-squared test?

Although I guess then you'll have periods where projects have been started and not completed. Hmmm.

Some sort of cohort analysis then.

I didn’t die, shifting was ok, only difficulty was the sprocket I removed was exactly the one I wanted for my easy spinning. Road bike gave me a few extra watts.

Can't you just plot a scatter chart of start date (or end date) vs duration, and then add linear best fit line?

It’s fucked now, look at current projects like DBAD, the gift that keeps on deteriorating
