Any question answered...

Presumably you are trying to fit a 3/32nd chain on a 1/8th sprocket?

Yes, that looks a lot like a 3/32” chain on a 1/8” sprocket.

Also interested as I have the same lamp!

I may have got the answer to this on another forum:

thats a really curious lamp the GX23 13W PL-S lamp was a US only size of lamp, originally the PL-S line up was 5W 7W 9W 11W, but the problem with the 11W one is its arc voltage was too high to be run effiecently on 120V mains (would of required complex and lossy autotransformer ballasts)

so a 13W PL-S lamp was developed which can be thought of as a high current version of the 9W PL-S lamp, now the 5W-11W PL-S lamps all and ran at roughly the same current and where designed to be interchangeable with each other

but the 13W PL-S lamp on account of its higher lamp current was not interchangeable with any other lamp so was given a modified cap to stop the wrong lamp being installed

note the double notches

as this 13W lamp was less efficient then the 11W PL lamp (they both where designed to target the same 850-900 lumens) it was never introduced, marketed or sold in any 220V-240V country

so I find it very curious that your handheld lamp claims to use these lamps! gawd knows where they expected you to get spare/replacement tubes from, 13W PL-S lamps just dont exist here!

I imagine such a portable light uses an inverter-electronic ballast, those generally are not compatible with LED retrofit tubes (and you would struggle to find a 13W PL-S type here in the UK anyhow)

so if your looking for an LED worklight, your best off just getting a whole new unit im afraid

This probably explains why I’ve struggled to even find a like-for-like replacement. I’ve had pretty good use out of this one though and it lasts a good 7+ hours on the 3AH batteries, so I shouldn’t feel too bad about replacing the whole thing when the tube dies.

I’ve got 20% left on my DI2 how many kilometres or hours is that?

^ Thanks both, I was not aware this was a thing.

Believe it or not, depends entirely on how much you change gear. I believe front uses more power than rear.

Would you go on a four hour ride in Essex 20% on your di2?

Why chance it? I think you'd probably be fine for four hours, but surely the simplest thing to do would be to charge it first.

Should be fine in theory, but bear in mind that the front will automatically stop working at 10%.

Someone’s borrowed my charger.

Ah ok thanks for digging out that info. Mines been going for years so I've defo had my money's worth.

Which flat pedals for under £40 should I be looking at?

About time they returned it then!

I always recommend the MKS MT-FT.
People laugh but it’s comfortable, cheap, pretty tough, has a chromoly axle, and replaceable bearings.

Oh yeah, and incredibly light.

Thousands of either if you don't change gear.

Nukeproof neutron evos for a tenner at CRC?

(And chuck in a rebuild kit for 7 quid)

My favourite pedals. Code EXTRA10 worked on my order too.

I need to get a cassette off today but i’m stuck in the country side and don’t have a chain whip- how do i bodge something to hold the cassette (i do have the other tools)

This sort of thing?

i’ll see if i can manage that, thank you

The clue is in your photo at about 3 o'clock on your sprocket. It says NARROW. What you do want is a single speed chain

I once used a strip of fabric, wrapped round several times.

I've fucked up the timings for dinner (lasagna).

I'm 15m short.

I par boiled the pasta. If I blast it in the microwave now for 5min can I catch up?

Edit : yes

Can anyone identify which tool I need to tighten this BB back up?

It looks like a Shimano external bottom bracket (Hollowtech or Hollowtech 2 or sommat). It’s usually a big cup thing that goes on the end of a ratchet, but it looks like you can get open-ended wrenches if you’re stuck and don’t want to take the crank off.

Sorry for Bezolink but this is the sort of thing: https://www.amazon.co.uk/Shimano-HollowTech-bottom-bracket-spanner/dp/B000NONYD8?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=A32CWL50OXRGYH
