Current Projects chat and miscellany

I got mine skimmed on a lathe worked a treat.

So options:

1) Try to find a new 27mm crown race and hope it works with the existing Campag headset
2) Find and buy a new JIS 1" threaded headset
3) Attack the fork crown with a lathe
4) Revert to the nasty headset that came with the frame

Option 1 is probably out as I'm not so optimistic about interchangeability of crown races and I don't have time to bugger about trying a solution that won't work. Option 2 seems like a good bet but I searched and couldn't find any on the obvious websites - either they were ISO/italian or didn't say (assume ISO). Option 3 sounds scary and I don't have a lathe. Sadly option 4 is probably the front runner (at least for now) but the original bearings have been lost - How on earth do I tell what size ball bearings my generic headset should take??

There is a specific tool for fork crown cutting which any frame builder will have, so option 3 doesn't actually have to involve a lathe, there's a standard, and better, way to do the job.

Option 5, ream the crown race. A job for your tame machinist, but it would only take a moment in a lathe to add 0.4mm to the crown race bore, and if it goes tits up you've only trashed a cheap component, not an expensive fork. Measure everything carefully before you cut any metal.

final product:

i dont know why, maybe due to picture's composition, but bike looks very heavy and thick in the front, and very light and skinny in the back - even the rear clearance looks too big
i generally dont seem to like black bikes...

I had option 3 done recently on some old JIS forks. No problems. I don't know what tool was used but as tester says - a frame builder will be able to to it.

I had some corrosion on fork crown seat so emeried that down a little, but then found crown race still wouldn't fit. It was a supposedly 'NOS' headset. Figured out why in the end that it has sat for 25yrs+ without being fitted to a bike......... it was egg shaped. Must have been dropped at some point onto a hard surface and the race was oval enough not to fit. No point reaming the internal as the bearing race track would still be oval. >>>>> NOS???? >>>> NO> >>> FUCKED >>> BIN

Fuckin'g hell, are any of these precious to you at all?!

This one is because it replaces the one that got smashed by a motorist whilst riding back from the track.

if you don't mind me inquiring, has the motorist coughed up then kc? or was it through their insurance?

Coughed up day just got this last night.

i do like it in white.

makes a nice friend for the panasonic.

Looks like agony to ride, but I like it. A lot.

i finished "her" today... Well, she's not as i wnat her to be. I will try to find a half link. I use 48t/17t and with that the wheel does not fit as i want. A half link will resolve that. I want the rear wheel closer to the seatube.

today i will ride her for the first time. I never rode a bike with 165mm cranks and with such a tight frame. Firts thing i've noticed was the position of the saddle. I'll have to set it a bit higher. The BB on this bike is higher than on my other bikes and that changes my position.

Lovely, Noca!

Does anyone know of any (semi-)'low profile' early 90's saddles, besides the Regal, Flite, Turbomatic and Trimatic?
I want to replace my SLR..

Very nice Noca! Rear wheel looks fine with front and rear clearances matching.

Nice one Noca.
You've now beaten the great Scoble, in number of times posting your own bike.
Well done ;D

Oh, nice bike too!

well, i think that Scoble will have alot of time to beat me... i will not start a new project so soon. Now it's time to let some of my bikes go. ;)

Vast amount of envy coming from me here...

+1 you see loads of track bikes running ridiculous fag paper rear clearance and polish sausage clearance up front (genuine technical terms).

What stem is on this? (from page previous)

24" Dedacciai Zero frame.
10 speed.
Built up with mainly Record except Chorus shifters and calipers.
Ambrosio Excellight rims on Record hubs.
Spin titanium skewers.
Cinelli Grammo stem.
Ti Chorus post.
Ti Flite saddle.

Nice. Love to see a frame like that brought up to date. Excellent!

looks like an origin8 logo on the stem, but can't be bothered to hunt down confirmation.

hunted, and failed. i dunno.

also agree, looks better as it is.
