Found this being sold for cheap locally, and I was wondering what type of frame this is, or if it is even a legit cinelli frame:
Tried googling it, but I can't find any leads. Thanks for the help!

Start by contacting Cinelli with your frame's serial number, and whatever details you've got, like country of origin.
I would suspect its a `90s bike based on the fat frame tubes, back when Aluminium frames were overbuilt to account for the material properties of AL.
It may have had downtube shifters, but those bosses were also a normal fixture for integrated brifters.
The Maxzone headset is out of place - that brand seems to have origins in the Philippines. Decidedly a long way from Italy. I suspect this is more of a local replacement rather than an original part.
We can't see details of the outboard BB, but presume its been replaced too.
The frame clearly has a derailleur hanger, possibly non-replaceable, but can't really tell. Whereas googling "cinelli mash" returns a lot of single speed and fixed gear stuff from the 2010-2020 period. So I presume that MASH was something and has been "pivoted" to single-speeds because of trends.
Or its a sticker/decal that someone has slapped on the frame.
The only thing that puts me off the frame is that horrendous weld around the headstrap reinforcement. It looks like painted bubblegum, and while I have no welding skills, that looks janky.
If you give it a good inspection all over, and see no damage then its probably okay to ride. As long as the frame's a good size for you and not damaged, and seems like quality then whether its "real cinelli" or "Chinelly" doesn't matter that much.
Ultimately, you need to guess the cost of all the other parts you'll need, and the cost of the frame/fork, and see how that total compares to buying a complete bike, either new or used. And availability comes into it too, this post-C19 world has some messed up supply lines.
The decals say that the bike is a Cinelli MASH. Based on the documentation in the Cinelli catalogs this is not a Cinelli MASH. All MASH bikes were track bikes - this one is not.
It's a track bike that was inspired by a movie that appears to have been made in 2007 about "the fixed gear bike scene in and around San Francisco".
According to this timeline the MASH model was introduced in 2009.
I can find no Cinelli MASH models with frames that look like the one in the original post. The MASH model was a single speed track frame.
The current evidence leads me to believe that the decals are not original.
I can't find a bicycle in a catalog anywhere that has a frame like the one in the original post. There is a large gap in the catalog record between 1988 to 1992 and another large gap between 1992 and 2009. In 1992 Cinelli has all steel lugged bicycles so the area to focus on would be '92 to '09.
You have been given a number of answers suggesting the frame is not genuine Cinellli, perhaps because the welding is so obvious or because the decals are not correct.
I think it is obvious that the decals are incorrect, it looks to me like the frame has been repainted and a cheap set of Cinelli Mash decals have been fitted over the new paint.
Most of the earlier Cinelli frames -- and maybe the current ones too -- use Italian bottom bracket threading and if yours is Italian thread, it's a good clue it's a genuine Cinelli frame. The fact you have a stamped plate with the Cinelli logo suggests it is probably the genuine article too.
If you look back over the Cinelli catalogues, you can see this syle of aluminium welding is quite common at different times and was considered perfectly acceptable -- even desirable! -- at certain times in cycling history. All the Cinelli bikes cannot really be considered "mass market" as the volume of production was much smaller than many rivals. Image search may give you only one or two examples of each type of frame from a given year - if that - so not being able to find a match doesn't tell you anything. It's worth asking the distributor for your region if they recognise the welded C plate on your bike and can suggest the model, not that it really matters. It should be light and built up, it will ride like any quality mid range early 2000s aluminium frame; if that's your thing, it'll be great.
The paint looks nice. A beter decal kit would improve the look of the bike slightly. If you build it up and like it, that's probably the most important test.
It's a shame there are no Cinelli catalogues for such a big time period, it makes it hard to identify so many models.
