Thanks, Eric. I've very recently experienced the same with my saddle
height. I suspect my self-estimated pbh was low, as a 73 saddle height
feels fine and, yes, faster. That brings the 60cm within range, but I'll
keep looking. And will do!

Hi Matt — Welcome! And I hope you find a Platypus that fits you well. Where
are you located? Maybe we can help find someone in your area so you can
have a test ride before you buy a frame. I think a 55, as you say, would be
more versatile.
I have a 2009 Hillborne that's a 57cm and a 2021 Appal
It may work for some but I have never been comfortable going by riv's
sizing standards of going big.

I just pushed my saddle height to 73 and was pretty comfortable, so the 60
might be within reach according to Will. I've spent so long on recumbents
and Bromptons that I haven't really needed to know the optimum height.

Tall guy!
If you’re in NJ or eastern PA, Delaware area you’re welcome to try my bike.
At that height, you might be able to do a 60. It is pretty big though. I’m

Thanks, Roberta. This experiential data is very useful. I'm 5'11 with
long-ish arms and torso, but a 60cm does look a little too large. I can
ride a saddle height of 73cm, but I'm just as happy at 72cm, so the 55cm
seems to be more versatile.

Welcome.
I use the heel to pedal method also for saddle height, and modify as needed.
My PBH is also 83 and I ride a 55 Platypus, which is perfect. Years ago I
test rode a 60 Cheviot and it was way too big. I think 55 is your size.

This is all very helpful. 55cm seems more versatile. I'm unlikely to put
drop bars on it, but, still. If I can find a used bargain I'll try a 60,
else I'll go for the 55. Really appreciate the kind and quality of feedback
here.

Of the methods I've read about that is and older one (1960s?) and gives a
lower saddle than others; for me, a saddle quite a bit too low -- I did use
it myself long ago. Of course, all of these methods are simply starting
points.
To the OP: be sure to get your saddle fore-and-aft position in place
I use Joe's method as well.

I heard somewhere a million years ago that you should be able to rest your
heel on the pedal with a straight leg. If you stretch it's too high, if
your knee is bent it's too low. Sounds ridiculous but it's never failed me.

Hi Matt, and welcome.
A standard starting height is PBH minus 11. If you’re rocking back and
forth to keep your feet on the pedals, it’s too high. If it’s not too high,
maybe it’s too low. Play around.

The most accurate SH would be using a gonimeter to measure your leg angle
and adjust SH to get the optimum leg angle (I forgot the value). The bike
is bike is on a trainer and the front wheel is leveled. The gonimeter
measures the leg angle at the bottom of the pedal stroke.

Like others have intimated, it sounds as if you’ve been running your saddle
much lower than recommended. I would suggest measuring your PBH one more
time with an assistant to be absolutely sure it’s correct, then adjust your
saddle to PBH minus 10-10.5 cm.
Alternatively, you could use the LeMon
IME, there's no objective way to get the "right" saddle height, but the Riv

so, even on the same bike, depending on the kind of riding I'm doing
(single track vs path/road/gravel) and how flexible I'm feeling at any
given

15 yrs ago I measured my PBH at 83.5 and my saddles were at 72.5 with B17
and up to 73cm with a Flite using 170mm cranks and clipless MTB pedals.
I am currently measuring my PBH at about 83.0 and my saddles are 72.0 +/-
5mm. I notice with thin flat pedals and thinner shoes I can be comfortable
Steve Hogg is the master wizard of real world fit, IMHO. His use of a
goniometer to measure leg angle and thus determine saddle height has worked
for me. My local shop has one, so they set the height on the two bikes I
ride the most. I then measured from crank center, in parallel to the seat

I've never measured saddle height, well, I suppose I tried once and I
observed that there appeared to be enough room for error and variability in
measuring based on the type and position of my saddle that I wasn't sure I

across
Good point, I do shove the saddle back as far as it goes on an offset seat
post. I've been measuring along the seat tube. That would make a difference.

Hi,
I haven't seen anyone else mention this, but when I set my saddle back,
like way back on the Nitto lugged seat post, I have to measure my saddle
height from BB to where my sit bones go, not parallel to the seat post
tube, thus lowering the saddle more in relation to the ground.

Thanks for the input everyone. Seems like the 10cm delta holds for a lot of
folks, but they're riding with "normal" shoes and pedals. For those of you
in that camp, are you also able to reach the pedals in the down position
with your heels? Just curious.

PBH x 0.8*8*3 = Saddle height.
I ride just a bit lower than that.

I have a couple of formulas in my garage, using cm:
PBH x 0.69 = Frame Size
PBH x 0.833 = Saddle Height
I believe I got these from one of Grant's writings. My Riv custom follows
these formulas. My PBH is 89.2 and Grant built me a 61.5cm frame and my
saddle height is 74cm using 175mm cranks an
Don't forget to factor in your crank length.
5mm difference in cranks equals 10mm in the full revolution.
5mm shorter means 5mm less at the top and bottom of the stroke.
Go from 165mm to 175mm cranks and you may find your hip flexor, knees and foot
muscles as well as calf and Achilles' tendons

I ride in sandals as well, and with a midfoot pedal placement, which has my

My PBH is 88 cm and I put my saddle heights at 78 or 77 cm. That works
well with thicker-soled shoes like Keen sandals, but if I take a ride with
thin-soled shoes like Vibram Five Fingers, that saddle height is too tall.
It's easier to change my shoes than it is to lower (and then raise) the
