Any question answered...

you can't file the top to make it square to the steerer

Damn, I've been doing it wrong all these years. OK, not strictly speaking a file, but I always smooth them off with a stone in the Dremel® even if the saw cut is perfectly flat.

Carbon?

I'd have thought that would lead to fraying of the fibre.

Carbon?

Yes, never had any suggestion of de-lamination. For something people trust with they're lives, people seem to have a low opinion of carbon fibre's ability to hold together :)

I have a frame that takes a 386 bottom bracket. I have a Sram GXP chainset. How do I make them work together?

ali canyon?

no.

This looks like a circular argument to me.

I had a mate who swore by scissors as the best way to cut pizza.

It'll change your life.

She showed me, I just bottle it when faced with the challenge myself.

I had a pair of BB7s with Campag levers. They were awful, no modulation, no bite but most infuriating of all, needed near constant adjustment as every time you used them they'd slacken off. This was way back in 2009 though, when their weren't many options for cable discs.

I've used both BB7s and Spyres with SRAM S500 levers and the latter were much, much better than BB7s. I'm not sure if they would work as well with Campag levers though, as I'm not sure if the cable pull on them has changed in the last 8 years. But then I don't know if it was the cable pull or the BB7s that were shit, always assumed it was the latter.

Understandable. I was overwhelmed too, but it helped to practice on toast first. NOT wholemeal obviously.

It kind of is, by the DVLA. They wanted an easily read typeface which worked with simple metal embossing tools in the olden days, and concluded that they couldn't tell O from 0 without making the production process more complicated than it needed to be. Therefore, they came up with a registration mark allocation system which, while distinguishing between O and 0 for administrative purposes, never required the reader to make the distinction. If somebody told the cops they'd been run over by ABC12OA, the cops knew it was really ABC120A because ABC12OA is not a valid registration mark.

Forrins tend to use the slashed zero, but English people would not have seen those until computers started appearing in every office with dot matrix printers which had the same O/0 distinction problem.

Despite what Park Tool® would have you believe, your mate was right. You can even get special scissors for it

I should have said elliptical.

Your friend's a genius

Currently only have that pipe cutter or the shittest junior hacksaw imaginable- will prob either need to get the right tools (good blade and something to guide it) or maybe just lbs

Thanks Andy!

@edscoble has been a proponent of scissors for cutting pizza for years

Not me.

I do have a low opinion of mistreating it though, which I'd say filing across the cut end is.

I dare say using a high-speed (relative to hand filing), smooth (relative to a file) abrasive around (not across) it is fine.

But that isn't what I cautioned against.

that isn't what I cautioned against

Fair point, and you're right that files should be avoided, as should ordinary saw blades. The right tool is a carbide coated abrasive blade. HSS tools will be blunt long before you've finished the cut, and then they will start tearing the composite apart rather than cutting it.

No, really!

I'd loan you mine, but considering postage each way, unless you've pissed your LBS off, it hardly seems worth the effort.

Most especially for Roman Pizza al Taglio.
