Hi. I am 44 years old and 191cm tall without shoes and i am looking to order a Cinelli Supercirsa Road Bike frame set. Also note thet my shoe size if that matters is 14-15 US

I am confused between size 59cm and 60cm Size Frames.

The 59cm frame has 57.5cm top tube and 587 Stack and the 60cm has 58cm Top tube. and 597 stack.

My inseam is around 89 - 90 cm .

Both Sizes have 73 Degrees Seat Angle and Head Angle.

Any help will be appreciated.

Thanks in advance

Stack and reach are the values that define the fit. Stack affects the possible saddle to bar drop, as does stem angle. This frame has a threaded steering tube, so it must use an old fashioned quill stem. What's confusing?

You didn't post a saddle height or a saddle to bar drop. That's more important than inseam, unless you're considering a size that you can barely stand over. I visit a forum where a very experienced rider always deliberately buys a frame that he can barely stand over, based on how little post is showing. That's not what I would choose to buy, over and over.

My last steel frame was a Tommasini Sintesi, back in the mid 90's. With an 83cm inseam, I rode a 55cm, but if I was buying one today it would only be a 52-53. I use a large saddle drop in the 10-11.5cm range.

Well my preious bike which was a fixed gear bike was 58Cm Seat tube and 58 cm Top tube. This is going to be my first road bike and i just want to get right the size. It confuses me because the cinelli corsa is a vintage bike which sizing was different than modern bikes . I still think that the lowest i will have to go for Cinelli Supercorsa will be 60 size. I might need a 61 which has same top tube (58cm) but a little higher stack but i just want t be in the safe side

Toe overlap is not generally considered a problem, but with 14/15 size feet, it might be a concern. I am 186cm tall (44 cycling shoe), best frame fit is 60 +/-1cm with top tube of 58 +/-1. My wingspan exceeds my height by about 7cm and I use mostly 12cm stems.

Such a nice bike, being 1st road bike, maybe a fit is in order? Without info about your current riding position and flexibility picking a size is mostly guessing.

Assuming you want to replicate the position on the fixie (not stated), I would measure the distance from seat post to handlebars on the fixie and buy the Cinelli in the largest frame size that equals the same measurement with a 10cm stem.

At your height a 61cm frame seems small - but I'm just guessing.

not sure what you mean by this?

most bikes with sloping down tubes will have a size chartt, and many still size as a 58 or 59 cm, but that is not actual measure, it is a measure to give an equivalent to a flat top tube size, measuring from center of of Bottom bracket to a level line from the head tube

so 58 "modern" is equal to 58 classic

For the physical fit, there is basically no functional difference between the 59cm and 60cm frame. There are enough varieties of stems, and enough adjustability in the seatpost, to make either frame fit you fine.
Now the most important question is... the look! Depending on how high you set your handlebars, on the larger frame, you could end up with too much stem showing, which looks bad. The taller frame will hide more of the stem, and look more proper. If you are in the habit of slamming your stem, then this is not an issue. Or you might even prefer the smaller frame so you can slam your stem down further.

I am 6 foot 1 inch, (185.42 cm) and initially purchased a 60 cm Paramount in 1986. Was probably a tad too big for me. About 20 years ago, I bought a Cinelli Super Corsa frame, in 58 CM. That fits me much better.

You, at 191 cm, are about 6 foot 3 inches, so I'm thinking the 60 might be better for you. This would also help with any toe overlap.

Spending this kind of money on a frame, I might take the advice to get a professional fit. It might be worth it.

EDIT: Oh...and with threaded steerers, "stack height" means something different to us. 58 cm below:

.
...59 cm frames and 60cm frames are close enough for me, that I can ride either, adjusting saddle height and reach, using different stems. At 6' 2", I have short legs and a long torso, other people have longer legs and a shorter torso, relative to overall proportions. If I were spending that kind of money on a custom Cinelli SC, I would seek out someone nearby who does this kind of thing, to take some measurements of my body, and act according to his (or her) advice.

You'd probably be better off buying a used steel framed bike in size 60, cheaply, and riding it around a while while you tweak the fit.

At age 44, I don't know how flexible you remain, or what sort of riding you do. Generally, now that I'm an older fellow, I tend toward the larger frame and almost no drop from saddle to bar. I'm not fast any more, so I might as well be comfortable.

Here are two Cinelli SC's, set up for me as I now ride. I think the frame sizes might be a 1cm difference. They both work fine for me.

that is pretty

Thanks, SD.

Couple of nice looking bikes, 3A. No pump pegs or second set of bottle braze ons...about what years are they?

Some people with your measurements might prefer the 59cm and some people with your measurements might prefer the 60cm frame. Some might be okay with either. You won't know till you get one and ride it for a while.

The last bike I bought I tried out two different size frames. For the ride around the parking lot I liked the larger frame. The salesman actually offered to let me ride them both on the local MUP. So after ten miles on each bike, I found that the smaller frame was the one I preferred.

If you can't ride the bike or a similar frame geometry bike before you buy then you just have to roll the dice.

Man, georgehomme, after looking at the Cinelli Supercorsa page, with its photos of bare frames, bottom brackets and fork crowns, I hope you'll share this journey with us! Keep us posted about what frame size you decide on, how you decided, what color you're getting, the ordering, building and delivery process, and definitely photos as you're building it up. I bought my frame from a shop, so I never got to go through the whole ordering process from beginning to end.

EDIT: Didn't realize 2023 was Cinelli's 75th Anniversary. Wonder if there will be any special touches on Supercorsas built this year?

...honestly, I have no idea. They showed up on the local CL at prices I could manage about a year or two apart. The Tuscan yellow one had rough paint, and there was some rust spotting on some of the chrome, so I stripped and painted it. These are the only bikes I ever bought that came with the early Super Record rear derailleurs, and the white one is pretty likely bearing the original components. So probably in that same time period of early Super Record. '79-'83. I'm not real good at aging stuff like this. It's not what I rode for most of my life.

Fair enough!

georgehomme

I will go for size 60. Probably my size is 61 but i will go for a size smaller. Both sizes have a 58cm Top tube which i am familiar with. 61cm has a 86.1 Standover height which i think is going to be on the edge of my height and inseam. My height is 190 cm and as far as i understnd i am between sizes 60 or 61. I have chosen to go for size 60 and Verde Jaguar Color which has standover around 85 cm

I will kep you udated with the build.

Delivery time is 3-5 months

That’s what I remember when I ordered my Paramount. The cost of quality.

What parts are you thinking of using?

I ordered a Cinelli SC 59cm early Feb this year. It will be ready late July.

I'm exactly 6' (183cm) tall with 35.5" inseam. My usual bike size is 58cm with 58cm horizontal top tube. I run 110mm stem. Reach around 400mm Stack around 589mm. My saddle height is about 79cm. For reference I ride a Factor O2 58cm, Cannondale CAAD12 58cm, Canyon Ultimate CF SLX size Large. According to the Cinelli SC geometry chart it's 59cm is about as close as to my other 58cm bikes while the 59cm size horizontal top tube is still on the short side at 57.5cm(reach 396mm stack 587mm). The Cinelli SC 58cm would be too short for me(top tube 57cm). I could even go with a 60cm SuperCorsa(580mm top tube), but I was afraid the frame is too big to be esthetically pleasing. I debated myself for a while between SC 58cm and 59cm. I went with 59cm in the end.

The classic horizontal geometry lugged small diameter tube steel frame bike looks best in 54cm or 56cm sizes. It creates the best visual balance with the 700c wheels. For we tall folks, sizes beyond 58cm the bike looks is bit out of proportion, IMHO.

I think you went about right (although I'd have gone for the 58).

Looking forward to the build!

at 191 I'd say the larger frame. if you get the 58 cm, you will need a taller stem that will look ... Fred.

bike in the pic is a 62 cm to top. I am 190.5 cm. Was just a tiny bit too big for me.

Not really true. I'm 6'1" riding a 58cm, and I don't need a "taller" stem.

Aero-X

Judging from how far back the saddle is on your SC 58cm, the top tube of a 58cm size is a bit short for you. Those traditional steel frames tend to have shorter top tubes. The Cinelli SC is especially so. They were designed for an era which has different riding position and bike fit methodology. On my other 58cm carbon bikes, my saddle is already at the forward most mark on the saddle rail. All of my seat posts have 25mm set back. I have pretty good flexibility(yoga/swim regularly). So if I got with a SC which has even shorter top tube, then I have to get a seat post with a bigger set back which changes the esthetics.

BTW, your SC looks gorgeous.

smd4

Thanks. The saddle has since been moved forward. Just haven't gotten an updated pic.

I would never choose a traditional road bike frame size based on top-tube length.

mpetry912 

that's a nice lookin SC you have there, "silver frost" color.

As for sizing, well, every "body" is different. Ben Serotta told me that top tube length is the sizing metric. I don't completely agree, but that's one way.

I look for the "equilateral triangle" angle of arms and body when riding on the bar tops, and legs not over-extended.

but sizing is an art, too complicated a topic to fully cover here.
