Atlantis Sizing

[Dick Combs]

Hello all, I have a PBH of 83.5, through the years the Atlantis frame sizes fitting that PBH have changed. Could anyone tell me what range of years and frame sizes would be appropriate for a PBH of 83.5, Thanks

[Brian Turner]

I'm right there with you; 83.5 / 84 PBH, and my saddle height is around 72-73cm. From what I've read and seen, you'd probably be a solid 53 on a Toyo-built Atlantis. I've ridden a Toyo 58, and while I found it comfortable to ride, it was really only because it had skinny tires and swept-back bars. I would love to find a 56 Toyo to try out.

Current models, you'd be a 53 or 55 depending on what tire sizes you'd prefer to run. Personally, I like fatter tires and prefer riding rougher terrain, so if I were to look at a current Atlantis, I'd go for a 53.

I'm sure there are folks who have more real riding experience spanning all years of the Atlantis, who could better advise.

79pbh, 31 inseam, and I own a 2004 Atlantis in size 53cm.

Thanks, appreciate it

Here's an original Toyo sizing chart, this will work with Waterford models, too. I'm shorter and would fit a 53, I think you need a 56 in these frames.

I agree, I have well over a fist full of seatpost on my 53 with my 79 PBH.

Not trying add complexity to the topic. I have a 83 PBH and  ride a 54.5 (Toyo) Atlantis I purchased new from Grant back in the 2002/3 timeframe. I am not sure how long Rivendell actually made that frame size but for me it feels like a custom

OP what’s your location? If close to Sacramento you’re welcome to ride my 53.

Ah, Joe the chart you referenced makes much more sense than the one I was looking at, which was from a 2000 RR (#18), where the Atlantis was first introduced. I'm attaching it here, but probably not good to use as a reference for all Toyo Atlantises because you'll notice there's no mention of PBH anywhere in the chart (nor is it mentioned in the article), and perhaps it was so early in the stage of this model that the sizing hadn't been fully worked out? I dunno.

[James]

This is good to see but slightly unfortunate.  There are a couple beautiful 61 cm Atlantis's for sale but as a 92PBHer, looks like I will indeed need a 64

[Joe Bernard]

Well it's all quite subjective and there's so many variables involved, which is why Grant doesn't like to post geometry charts. According to your PBH and saddle height numbers you're kinda on the cusp of 53 and 56cm on that early Atlantis page, and you have to consider that this was still deep into the drop/moustache bar era. The 56 is pretty dang stretched so you'd probably want the 53 unless you're running pullbacks. Simple, right? 😂

[Joe Bernard]

Ah dangit, I think I said that backwards. 

Shorter version: the original Atlantis was designed with drop/moustaches bars in mind, the size you need depends a lot on which types of bars you run. Pullbacks like Bosco or Billie? Go big! 

[Brian Turner]

Nah, your point was understood. This explains why when I ride my friend's 58 Toyo (with the equivalent of Billie bars), it's doable, but just to big of a frame size to try to shoehorn into my riding style.

Now this discussion has me pondering a search for a 56 Toyo (last thing I need bc I haven't even fully funded my current Riv project!). Hmmmm

I'm also at 83.5 / 84 PBH. right on the cusp of 56 & 58 when Toyo was building them in 2003.  I went with the 58 & have been happily riding it since then.  Started out with a 100 mm stem & Nitto Dream bars.  A few years back, I went to swept back bars & a dirt drop stem for a more upright position. 

FWIW, the difference in chainstays (44 cm vs 45.5 cm) was the deciding factor.  I bought it for touring & wanted max heel clearance.  Were I to do it all over again, I would go for 56 for the 26" wheels.  I've ridden a 56 Toyo but the difference is & not worth sweating over.

In 2017 (??) I rode a 56 Waterford.  It fit well & was very much like my 58 but there was something subtley different that I couldn't figure out.  Later I found that the Waterford's had ever so slightly longer chainstays, which probably accounted for improved ride.

A couple of years ago I was at Rivendell & they set up Taiwan Atlantis for me to test.  They knew what I rode & given PBH & saddle height, grabbed a demo & set it up.  After riding it for a couple of hours, including some off-road trails, I really liked it & the long chainstays did not have effect on handling on tight switchbacks.  From the fit, I assumed it was a 56.  When we got back to Riv, they told me it was a 53, which surprised me.  That was the best riding Atlantis I've been on & what I would buy today if I was in the market.
