Good luck with them. There is no standard, or quantified tolerances, on what actual inflated dimensions of a tire need to fall within to be classified as a certain size. I’ve had 25’s measure out at 22mm.

If you are using the original skinny road rims, with around a 14mm internal width, you’ll have a better chance than the newer wider road rims.

There are tons of threads discussing tire width based on rim width. In my experience I have found this to be true. As an example, when going from MA-40’s to TB-14’s, my same tires grew a mm.

This only becomes a problem when pushing the tire size limit and you need automotive feeler gauges to check the tire clearance… lol.

I guess I will know in 5 days when they finally arrive. I lucked out on my 1986 sr400, from all I know, it's the same frame, so I'm hoping it will work.

The rims are mavic MA40

I asked my LBS if they lace up rims and there's only one guy who does and he may or may not be in the mood to do it I was told... Want to keep the Superbe pro hubs, go black spokes, was hoping to keep the mavic rims, may be a folly.

During the winter, my 48cm SR800 run Vittoria Corsa 2.0 28 on older 14mm rims. Similar DiaCompe brakes to the RGC, and the rear is as tight as possible. The closest point on mine is the mount on the rear brake bridge. Clearance to chainstays and seat tube not a problem. Have non-stock forks, so can't comment of front clearance.

Rear chainstay bridge can be an issue in getting the wheel in. May need to install before inflating the tire or remove the quick release skewer.

Your rims seems to be OK. Maybe get them trued and plan to rebuild them yourself at some point. Lots of resources available to learn this. Building a wheel with 32 or 36 spokes is not too difficult. Sheldon Brown's web site has good info and tutorial on wheelbuilding.

I couldn't agree more. I only wish I could re-anodize and re stencil, but these are out of my abilities. I will continue to search for another just to use this one as a backup or sell. I needed a new nut for the dia compe Gran royal brakes, yellowjersey quoted me $41 for one conical nut, and two stock washers delivered, glad PayPal was giving me difficulty paying it after 6 attempts I was on the 'bay and found a complete black pair in case I go full Darth Vader/Batman, at least I got 2 sets of brakes and hardware in better shape than mine for $38.

Turning this thread to a (pre) Black Lightning restoration update

So far, need to install new gatorskin rubber arriving soon, black silicone tape is on, it's been cleaned and lubed, next up is a thorough tear down from a passionate veteran racer and mechanic who is a huge fan of this exact bik, it was the first bike he raced on in the 90s, was his stepmother's, she had the coral version with the pink bar tape.

Got a 1990 Selle Flite for my buns. Cinelli goes in storage.

Such great advice, love the idea of installing them deflated!

@StuBotNYC Looks awesome! Well done. You did justice to this little slice of Cannondale history. I am glad you picked this up and saved it instead of someone that would just continue to neglect it.

Thank you!

What a joy it is to ride, just rode it to the bike shop to thank the head mechanic, and after joking to him how my wife wanted me to ask him for a job, he said YES! Wants to talk to me in January when they start hiring, he said he would teach me how to be a mechanic! I have been working on bikes since 1978 believe it or not at the age of 10, creating Frankenstein bikes but never learned more than simple bike mechanics, I am floored that he thinks I have the right stuff

Oh btw, here's the drivetrain before and after...
No new parts besides brake cables and a saddle, the Cinelli went in to storage.

I can confirm, 28mm tires do not fit the 1986 sr800 "Black lightning", probably doesn't fit the other late 80s bikes but hard to tell, mine has Dia Compe Gran Comp brakes, may fit other brake setups on the tange steel fork, results may vary.

I installed 25mm continental gatorskin tires, works great

All good now! With the exception of one bad pilot wheel and worn off lettering on the rear derailleur.

See pics?

Thanks! Funny the term retro to me when all the bikes that interest me still were made in my lifetime. This bike was offered for sale when I was 18, I would have really loved to own it then, but I do now!

Both the drum kit and the bike are from just about the same year! This amazing Yamaha kit is also an outlier: this all black Yama kit pre-dates the subsequent kits named Pro "recording series" and Stage series kits, this kit was the jump off design for these two legendary drum kits, same as my SR800 Ebony Special edition!

It all depends on the tire and the rim. Brakes have an impact when it comes to height. I would think seat tube angle also impacts tire size as it gets slacker.

All 1986 SR's have the same geometry (pre-criterium) regardless of the exact model. The only differences are the groups and the fork material. SR600+ CroMo, SR500- Mangalloy.

All 1988 SR's have the same criterium geometry regardless of the exact model. The only differences are the groups and the fork material. SR700+ CroMo, SR500- Mangalloy.

What is noteworthy is that even though the criterium geometry changed, the chainstay length 15.75" remained the same between the 1986 and 1988 for every size; 48cm to 63cm. Seat angle gets slacker with larger sizes size.

I can fit a 28mm on my 1986, but I don't think it is possible on my 1988. But if I ran the exact same tire on the same rim it should make no difference. I should be able to swap out the rear wheels; except there might be differences in brake caliper clearance.

Something I learned, that is not applicable to this discussion, is the top tube length didn't change with the criterium geometry. I realize that this is not the design approach taken, but it is almost as though someone ran a pre-criterium Cannondale into the back of a car and slightly crumpled the downtube, loved the handling, and it became a revelation for the steeper head angle.

lol don't worry it's happening to all of us. I was playing a racing game the other day and it had the Ferrari 360 in the category of "Retro Super Cars" and I was floored. I was like no... that's modern... but I'm out numbered in my thinking. "Retro" is cool now right now, so we'll enjoy the wave.

I'm glad you got the bike you wanted and it's in good hands. I have never seen this bike before but it looks absolutely amazing.
