We don't like jacka$$, however.

An 80's Nishiki ain't rare. I've filed the front end of a fork a few mm's often on various frames to get better tire/fender clearance, and have modified dozens of frames for 650b conversion. And note that the pro peleton is riding 28+ nowadays. Lottsa races being won on "Lincolns". Pretty sure they wouldn't be riding wider tires if they were slower. And my God wants everyone to ride wider tires. So there.

OP, The Bike Butcher of Portland sez mount 28's, heck 30's or 32's if they'll fit.

Oh, we have a name for that already.

But I do agree that fixie idjits castrating perfectly good road frames is very bad form. The Atelier has received several bikes that I've brought back to the world of rear derailleurs and restored other tiddly bits. Here's one I did for a forum member.


New derailleur hanger brazed on


Filed and sanded. After that, derailleur hanger alignment tool goes on for fine tuning. It's a common repair at the Atelier

Nope. I file 'em down all the time, usually when I'm building a scratch fork. It only takes a couple of minutes with a coarse half round file, followed by a fine one to remove visible file marks, then 80 grit garnet cloth to finish. And having the steerer stick out a bit from the fork crown while brazing is the typical construction method. You can introduce the filler material more easily that way, then file the excess. As noted by others, a production fork shop for a mid-range quality frame didn't bother to file them back in the day (saving labor), whereas a custom framebuilder definitely would.

Touch up paint in an area that no one will ever see except the OP.

I just had a Rawlands in the Atelier to move some cantilever bosses so the owner could go from 650b x 38 to 26" x 52 (we did a fit check with wheels to check clearance and BB heigh change first). I asked if it was getting repainted or powder coated, he said he'd just mask the areas off and rattle can it. He told me he likes to ride bikes, not stare at them in the garage.

My dad, who was an Army cook in Europe during WWII, occasionally sang what might have been the origin of that bit of doggerel:

Oh, it's beer, beer, beer, that makes you want to cheer
In the Corps, in the Corps
Oh, it's beer, beer, beer, that makes you want to cheer
In the Quartermaster's, Quartermaster's Corps
(My eyes are dim, I cannot see
I fear I have not brought my specs with me)

Oh, it's wine, wine, wine, that makes you feel so fine
In the Corps, in the Corps, etc.

Oh, it's whiskey, whiskey, whiskey, ... frisky, etc.

Yeah unfortunately that was the high point of my comedy career and it's been downhill ever since.

In a desperate attempt to bring this back on-topic... Here's another fork I applied the bastard to:

The scratches you see are from the sanding drum I used to take the file-marks out. I could have just done the whole job with the sanding drum, but it's slower. The half-round bastard takes off metal in a hurry.

The bottom of this crown, on a Soma fork, has the dumbest shape you ever saw. Before filing, there was this projection down towards the tire that does nothing for ya structurally, just removes scads of tire/fender clearance for no good reason. And the crown designer put that downward projection in there on purpose, i.e. not just a lack of trying to remove the extra, like on the OP's fork. This stupid thing was intentional!

I didn't take a pic before filing, but in case you don't know what I'm talking about, here's a pic from Soma's website that shows it:


I don't blame Soma for the dumbness of the design — they didn't design it. The crown is actually pretty decent, other than that dumb downward projection, and this fork is now a good fork, now that I've filed off the offending part. The steel will rust there where I took the chrome off, but I can live with that.

The crown is made by Long Shen, I think. Here's another view of the LongShen crown:


But the design is a faithful knock-off of a Cinelli "OR" from the '80s.

Above is the Cinelli catalog drawing, below is a raw crown:

So I blame Cinelli for the dumbness.

Here's a "real" Cinelli OR (cast in Italy I believe) that I heavily re-worked for one of my MTBs:


You can't necessarily tell from the photo what-all I did, but I lightened it up considerably. (I "heavily lightened" it??)
I raced and toured and knocked around on that fork (built in 1984) for about 20 years, and I am a clydesdale+. Still have that bike in fact, though it doesn't get ridden much anymore. So it's definitely strong enough, despite all the metal I removed. Which tells me it was not an optimised design, as delivered from Cinelli — or the Long Shen copy.

'Heavily lightened' - I used to do that
