I have bad memories of those old Campy brakes. I do have a set of Potenza brakes I could put on there. Maybe that with a Racing T drivetrain. I hate to give up the Synchro indexed shifting though. I was actually pretty impressed with how well that worked. |

Andy, I like the monoplanars, have them on several bikes and they are capable of locking up the wheels, so less hand effort is what you get from double pivot. I think more power just makes it easier to lock up, and once you're in a skid, what then?
The Campy switch to double pivot brakes plus the monoplanar migration through the years from Chorus all the way down to Mirage made them available NOS and in VG used condition at bargain prices for a while, so it was a no brainer back in the early 2000's, when I built my bikes. New pads will make a big difference and there are better pads available now than when they were new. Don |
That’s a really neat bike. Congrats on the cool score! I always liked the red polka dot look, but not being much of a climber myself, I’d be out of place in a KOM Jersey. That bike on the other hand, I’d be glad to ride. :thumb: Do keep working on those brakes. They’re not always ineffective. I have those same Chorus monoplaners on my Look and they stop well. I can easily lock up the rear, and I’m using original pads. Try sanding off a little with a file to expose some fresh rubber. And double check the quick release at the lever isn’t open. Mine tend to stop better when adjusted fairly close to the rims (though they look fairly close already in the photos). |
That bike makes me smile, Andy. Love it!

Hey, the decal says "King of the Mountain", not 'King Of Riding Up The Mountain'! |
Dig!
Kool Stop inserts will transform those brakes. Have them on a Viner of which work excellent even while scrubbing scrubbing GP4 anodized brake walled rims. Found this stock image Serotta 'JOM' https://cimg8.ibsrv.net/gimg/bikefor...6329a77ec3.png |

The dots appear to be decals, but they're under a sort of sparkly clear coat that covers the entire bike and also the stem. The other thing I should have pictured is the rear stays. It has "S-bend" chainstays. Supposedly this makes it stiffer. I think that also may be part of the "Colorado Concept." I actually thought about you while I was out riding it today. I didn't push it much because the brakes are barely functional (almost hit a couple walking their dogs because of that), but the first time I went up a hill I definitely noticed the response. I don't know if that was the Colorado Concept doing its job or the new bike euphoria doing its job. Either way, it reminded me of the way you described your Casati (and my brief parking lot experience with it). You'll have to come down and try this sometime and see what you think. The 24T cog on the freewheel might not be to your liking, but I'm sure I can find a corn cob to put on there for you. ;) As for the gearing, if I put a 14-28T freewheel on it, it will match what's on my Gios. I've got a plan to keep riding on that until I can handle at least moderate hills. I want to test the theory that I'm weak because I never push a big gear. I suspect that I'll find that I'm weak because I'm too old to build new muscle, but you never know until you try. Today I am beginning to enjoy 24 and even 26t cogs out back. My knees appreciate them, too :) Too old to build new muscle? Is that a thing - because if it is, I'd not heard that before. Maybe that's why I don't necessarily get stronger, just faster, with accumulated miles. Lastly, those brakes will work perfectly well if they're set up correctly and the pads are supple. I run them on my Davidson with the Ergo 8-speed and have never had a problem with braking. While not dual-pivots, they still have better modulation than the older Record calipers. DD |

Perhaps Col d'Kaylor as [MENTION=381793]gugie[/MENTION] suggests. I picture a scenario like a couple of years ago when Taylor Phinney went out in a breakaway on stage 2 and got the KoM jersey for a day. He led a group of four riders over two cat 4 climbs and went on to finish 146th on the stage but got the polka dot jersey at the end of the day. I think I could manage the recreational group ride equivalent of that. :lol: |
Thanks to everyone who has encouraged me to keep working on the current brakes. I think I'll replace the pads first then the cables and eventually the rims if nothing else works. All those things need to be done eventually anyway and everything but the rims will be cheap. I didn't see anything obviously wrong with the monoplaner design, but given that people used to choose Deltas over these I had a lingering doubt. I guess some people just don't like stopping.

That looks really fun, I also will be trying out the monoplaner brake and just bought new pads. Now you need the polka dot shirt and hat. :) |

I would note, however, that no one even mentions the world championship stripes on my LeMond or Stella. Perhaps it's because those are slightly more subtle. |

It's actually even more unusual than that. The seat tube and down tube are tapered. They're both 28.6 at the top but around 36 mm at the bottom bracket. I believe this is standard for Serottas of this period (~1987). If I understand correctly, this is the "Colorado Concept" tubing that is (I think) unique to Serottas.

My (Schwinn) King of the Mountain(s) mountain bike is red, white, and blue (see signature), perfect for national holidays.
On a road bike with a 42T inner ring up front, I like a 26T large cog in back for hills. The very common 52-42/14-16-18-21-24 combination is a bit too tall for me. On the subject of Campag. brakes, I have early-generation sidepulls on my Bianchi. They were terrifyingly ineffective with Shimano pads and long-reach Modolo brake levers, but they work well with KoolStops and Shimano (I know, no style points on an Italian bike) aero brake levers. |
I was a mechanic, high end assembler, and occasional salesperson at a Serotta dealer from @'88 to 2000. The quality of those bikes is impeccable, yours may have been custom ordered because the CSI (custom option lugged frames) were sometimes hybrids of fillet and lugged construction when needed to get the customer's needed geometry. Often the main triangle joints were what some builders call "bi-laminate"--one socket cut off the lug and replaced with a fillet. The builders who did that neat **** were Kelly Bedford and Dave Kirk. Lueky you!! You could lower the gearing by changing the crankset and leaving the rear shifting alone--the friction downtime shifter is omnivorous, it'll work with any crankset you want it to work with.

If you are planning to overhaul it at some point, please share a pic of the BB shell mitering. Just looking at this pic of the shell without sockets makes me drool with anticipation regarding what the joint looks like from the inside :)

No offense to anyone here, but I would venture to guess that many of us are incapable of giving our bikes the full measure of what they were built for. Certainly true of me. I would look at that as an exceptional bike with a really cool paint job, and enjoy the heck out of it. That said, your thread title made me laugh. |

Way cool! Great acquisition.

I'm definitely enjoying this one. I'm often impatient about getting a bike on the road and so usually throw together parts bin builds to try it out. Recently I've been a bit more patient about that. In fact, I've got a Raleigh Competition on my workstand right now that I bought almost two months ago and haven't ridden yet. Not so with the Serotta. The day I brought it home I leveled the saddle, put on fresh tires, sanded the brake pads a little, and took it out for a ride. I didn't even have to change the saddle height. |
