Let me say this upfront—I'm not angry.
Really, believe me.
Due to circumstances, I'm reposting an article that went up on August 20th, as mentioned in the title.
Among cyclists in Osaka, there's a famous pass
called Juusan Tōge (thirteen pass).
It's about 4km (Osaka side), but with steep average gradients,
making it ideal for certain types of training.
I've been running practice sessions here since January 2004.
The "pass13" in this blog's domain name comes from Juusan Tōge.
Almost all images on this blog are my own self-taken photos.
I'm not saying there's anything wrong with grabbing images floating around online and writing commentary,
but personally I find it lacks substance, so I don't do it.
I basically don't post links to other blogs either.
Especially, I don't want to do things like taking credit for someone else's work.
So when links appear on this blog,
they're mostly references to my own past articles.
Of course, this is just a rule I arbitrarily set for myself,
and I'm not prohibiting others from linking to or citing this blog's images or arguments.
People are free to do that
(though there was once some idiot who cropped images from this blog
and posted them as if they'd done the work themselves—that's obviously not okay).
Regarding the Cannondale owner mentioned in this article,
I don't mention it in the article itself,
because I personally don't like saying things like "we built XX racer's bike at the shop!"
or "XX racer using our Nomulabo wheels
won/placed at such-and-such race!"
This isn't about being humble—I just don't like doing that.
If the racers themselves want to mention it, fine, but
I've never loudly promoted it myself
or asked racers to advertise for me.
As for this Cannondale owner,
they were introduced on the blog "Juusan Tōge 13-minute Cut"
and a link was posted to the article before this repost,
which I found annoying
(and I keep saying this, but I'm not angry.
They might get angry about what I'm about to do,
but then don't post the link in the first place).
So I modified the original article
and posted it with a timestamp of 2013/13th month (January 2014) 13th day at 13:13.
If you want to see the original article, searching by date would take forever, so
find the link from the Juusan Tōge 13-minute Cut post (→here) and follow it from there.
Done! Mutual linking! (they went first)
This is a story about what happens when you try to take credit for someone else's work—
sometimes you end up in situations like this.
After stepping into the ring, you suddenly realize
you're wearing women's underwear.
And lots of people have already seen it.
This kind of trap is why I don't post links to other people's blogs.
To Juusan Tōge 13-minute Cut:
Just as I'm free to modify my original article,
you're obviously free to delete and disappear from this situation,
but that would be a cowardly move—no fun at all!
I'm looking forward to seeing you do something clever enough
to make me genuinely impressed and slap my knee.
Go for it!

Original article before modifications follows below.
A customer (sort of) asked me to convert their bike to a front single setup
for Mount Norikura,
so

I did it.
The actual tedious work was fixing the outer cable routing that showed
absolutely no sense from the Cannondale shop that originally built the bike
(not my words—the customer said this, but I agree).

When converting to front single, with SRAM or Campagnolo levers,
you can remove the internals and put them back later, so

I converted the left lever into a brake lever.
With both SRAM and Campagnolo, the return spring for the shift lever also serves as
the return spring for the brake lever,
so doing this leaves the brake lever without a return spring.
But if the outer cable resistance is sufficiently low,
the brake caliper spring alone is enough to return
the brake lever.
If you assemble it so the initial performance lasts,
the result is actually a lighter brake lever feel.
I also fixed the rear brake, which had gotten heavy due to
improper use of beaded outer cable (some knockoff of Nokon-style cable).

The front derailleur clamp can be riveted on, so
I joked that if this frame were mine, I'd blow the clamp off!
They actually asked me to do it, but I declined because it's a hassle.
Pulling the internals from the lever and removing a direct-mount clamp would be
"true front single setup," I think,
but the clamp is irreversible modification, so it's better not to.
I'd definitely do it if it were my own bike! ←so stop egging me on
This customer (sort of) has multiple bikes, so
like I do, creating one dedicated hill-climb race bike with
permanent front single gearing and ultra-light wheels,
used only for racing and pre-race tuning, would be
better all around—no hassle, I suggested.
Also because converting the lever and everything back to front double is a pain.
Bonus
From here on it's about my own bikes.

↑SRAM Rival gen 1 left lever

↑Campagnolo Mirage left lever
Both bikes are front single, so
I've removed the internals from both.
In bracket generations, the Campagnolo is second-generation Ergopower,
the SRAM is first-generation Double Tap. Interestingly, both
also offer dedicated brake levers using just the bracket and brake lever without shifting function.
You could use those, but if you can revert the original, there's no need to buy extras,
so I extract parts from the shifting-capable left lever.



The Rival right lever is on a bike where shifting function isn't needed on the lever side,
so I've removed its internals too.
I run brakes as left front/right rear, and since I don't use the rear brake,
if the material is aluminum, I'll completely hollow out
the right brake lever I never touch.

Same with the Mirage right lever, except it has the shift lever attached.
I've upgraded the internals from 9-speed to 11-speed (→here)—don't worry about it.
