Sorry, wrong album.

I did something similar to my Cannondale touring bike before having it
refinished. But the dimples I added to the inside of the chainstays were
not nearly as extreme as yours. I'm wondering why you went so deep. And
I'm a bit surprised the titanium had the ductility to accept that.

I'd be curious about the tools you used for the job.

But if there were no cracks or other obvious problems, I think it'll be
fine.

Thanks, I can see it now. No narrow spaces in any bikes that
I've ever seen. Not to the point you can't fit "normal" tires.

The world is a very big place; What's 'normal'?

There are people who install big block V8 engines in
Corvairs too.

The range of possible is almost limitless. But we each see
problems differently with our own criteria for which things
are important and which are not. Many would sell that bike
(or frameset) and buy something designed for fat rubber but
Mr Muro chose his own path.

Is a chap near to my folks who has a business converting classics into EV’s
sometimes giving quite dramatic results! These like any classic cars aren’t
going to be daily runners, and most are more sensible ie motor and weight
ie batteries appropriate to the vehicle!

I’m unsure what I think of this, some cars are very much about the engine
for example the Porsche 911, others not so much!

Just a curiosity. I know you collect them. In Brazil if you
change ANY characteristic of an automobile(or motorcycle) you have to
re-register it as if it was new. There's a lot of legal stuff too,
best handled by a "specialist"(we call them despachantes). So it's
expensive.
For example, if you decide to paint your bumpers black, and
they were blue, and you haven't completed all the legal bureaucracy
before taking it for a spin, you can be arrested for driving an
unregistered vehicle.
If a touch of paint can get you in jail, imagine messing with
the engine. LOL
No idea why. Most of these laws are from the right wing
military dictatorship of 1964..... in a dictatorship, the government
doesn't need "reasons".

Neither Dima nor Bolsonaro nor Lulu freed you from

oppression? That sounds like a serious structural problem!

Neither Dilma nor Lula had a majority in Congress. Though
Brazil did have a massive increase in industry, employment and
salaries during their terms. Brazil went from 18th to 7th largest GNP
in the World. Both are Center politicians. Dilma was originally from a
party (the PDT)slightly to the right of Lula's PT.
Very few laws changed, though. A President cannot make
permanent laws. Just "emergency" ones.
Vehicle laws remained practically the same. Lula did manage to
pass a law forbidding drunken driving and was heavily criticized by
the press for it.

Bolsonaro was a daily reminder of the problem and the
oppression. When he assumed, he thanked a torturer from the military
dictatorship for "teaching him all he knew". His "hero" was fond of
torturing and killing political opponents in front of their small
children. He would then dump the children in far-away places, where
relatives could not find them. He would also masturbate during the
tortures. Ustra and Bolsonaro - two peas in a pod.

I guess when a regime has a practice of murdering political opponents in
front of their children, getting arrested for having different colored
bumpers isn't the first issue people think of at the ballot box.

Uk need to inform the DVLA of colour changes and at some point if the car
is massively changed then would need to inform them, and possibly be a Q
number plate. I believe that is some tidings up of that legislation
planned.

Sorry, wrong album.

The titanium frames I used in 2023 to build our new bikes didn't need
such a procedure. Neither did the earlier road bike that I bought in
2010, which had enough width for 25 mm tires.

On the new bike, I installed tubeless Continental tires, nominally 28 mm
wide, or almost 30 mm, when measured after inflating to about 4 bar.

I built our bikes as road bikes, but based on a gravel bike frame, so
much wider tires are possible. 28 mm is wide enough for our purposes,
though.

I'm almost always on 28s, but I did want the option to go wider than 32.
That's why I dimpled the stays on my Cannondale.

Hm. I have nothing against the option of mounting wider tires than 60
mm, given the frames I've used because of other reasons, but I wouldn't
risk weakening a frame for an option that I'd perhaps never use.

But ok, some things you do simply because you want to know if you can do
it. :-)

Here's how my motivation came about: We rode from Washington DC to
Cumberland Maryland on the C&O Towpath Trail, carrying full camping
gear. That was part of our coast to coast tour. That stretch is
literally a mule trail, very much unimproved. Since I was carrying a
heavy load (to make riding easier for my wife and daughter) I wanted
wide tires. 37mm fit, but just barely, and were scraping the chainstays
within a couple weeks.

I thought it was unfortunate, because the bike has plenty of room for
wider tires everywhere else. Since the bike was disassembled for powder
coating, I decided to increase that chainstay clearance.

I very much doubt the frame was weakened.

Doesn't look indented. Appears to be cut and shaped titanium

I briefly wondered that, but I was under the mistaken impression that

Back when CX was first becoming a thing in the US in the early 90's
legit CX bikes weren't really available. Most of us took an old frame to
a local frame builder who modified them by fitting canti bosses and
pinching in the chainstays. I found a Schwinn Tempo frame for cheap
(True Temper tubing) and he took the additional step of moving the brake
bridge up for better clearance.

I have done many of those, mostly well worn Italian race frames.
