I had this exact situation a few years ago. I filled the slots in front of the barrel with JB Weld, thinking the cable tension would keep the barrel at the back of the slot.. It fell out about 3 months later. The tension on the cable keeps the barrel in the "rear" part of the slot, but you get very little cable length on the pull.

A mountain bike mechanic looked at it and said "dude, those holes on top are for show." He was pretty much right, and not because he was experienced. He didn't know a Campy part from a Coleman lantern. However, his logic was different, and correct. I was trying to solve a problem that he didn't see. \ I ended up buying plugs at Lowe's. I should have just squirted some Plasti-Dip in there from inside the hood.

The wood fits very tight but still allows the barrel to rotate when the lever is pulled.

Pretty good solve.

I was intending to use them on my Masi so that the bike could be ridden in Eroica-type events. The usual configuration will be Chorus 10s shifter/brakes. My plan was to fit these, cut the cables and housings to length, and then put them aside. I'll have to re-wrap the bars to install them, but that only takes a few minutes. Adding a set of VO DT shifters, which don't require any housing, just cable, it's ready to go.

EDIT: Maybe filing a radius in the top of the slot at the front would provide a way to more easily keep the barrel at the front. There is plenty of metal there, so it shouldn't cause any weakness.

I might look into 3D printing a spacer to use in these levers, radiused at the front for the barrel. Maybe I should just build it without shifter/brakes from the start and leave it with brakes and DT shifters. I could sell the Chorus shifter/brakes easily. Something to consider...

You could also use some real 10sp indexed Campy downtube shifters. There are people on BF who sell them.
Classy look, old-school technique, modern precision. Makes you look down the road a bit, anticipate. No chicken winging.

And you know where to unload the Ergos….

Can I just jump in with some inane questions about Chorus brake levers?

The exploded diagram of the Record version shows a BL-RE006 return spring, but there isnít one on my Chorus levers, although Velobase seems to think there should be. Is this correct or am I missing a part?

How does that quick release pin work? I canít see how it Ďreleasesí as it hits the lever body in every position.

I don't think so, most cable stops are wider than the cutout in the lever. Press the lever against the handlebars and thread it in from the top.

@speedevil did you do the 3D printing? Where is the file available? I have my own printer.

@pbekkerh, I didn't pursue the 3D printing, as I traded the levers for other components. I decided to use Campy brifters on my Masi. I picked up a 1983 Pinarello that will be my Eroica-style bike, should I ever need such a machine.
