Wanted: Large black helmet, 42t chainring

55-63cm black skid lid please. (preferrably only Londoners, i dislike posting fragile items)

42t 130BCD 3/32" chainring. not too used but doesn't have to be spanking new either.

ring- what BCD please?

I'm having a 'mare day. OP edited.

Width of the ring?

Would a inner ring from an older road chainset not work? They were commonly 42T (now 39T) - You'll just have to look for ramping and pins on the chainring...

I have this helmet for £10:

It is hardly used. I doesn't have a size label but I can measure if you tell me how. 55-63cm seems huge for a helmet, no?

Is that the Bell equivalet of the stylus?
Not huge, just big. As a savant raffiné I have a greater cranial capacity.
No labels whatsoever, even under the headband? Measure around the headband (using flexible measuring tape or paper/tissue and a ruler) when it's fully expanded and do the same for the smallest adjustment.
How much btw?

Apologies, I think [deliberate] you were being funny. Cheers but too small (my small fro' only just fits in my current helmet). Do u know anywhere I can get a cheap 3/4spd coaster brake hub?

Sorry, I went off somewhere. Do you still want my chainring? I'll be central London this afternoon, or in SW14 for most of the weekend.
