Re: [RBW] Saddle height and BPH

2022-12-15 Thread Andy Beichler

I am not very flexible.  Even when I was young, before I hit my growth 
spurt, touching my toes was difficult at best.  I have a 92 PBH and run my 
saddle around 78 cm.  Anything higher and I feel like I am reaching for the 
pedal.  I usually just get it in the ballpark and adjust it if I start to 
hurt.

Re: [RBW] Saddle height and BPH

2022-12-15 Thread Patrick Moore

I agree that rules of thumb are only starting points. The heel-on-pedal at
max leg extension puts my saddle a good 3 cm too low as I like a lot of leg
extension and tend to pedal toe-down. But it's a good starting point.

And get your saddle set back to where it is comfortable before doing
anything else; IMO and IME, saddle height and setback are the 2 primary
adjustments around which all others are determined.

But heck, if you've been comfortable with your previous "4-inches-too-low"
and slammed back saddle -- no hip-rockin', no aching quads, no strained
whatever it is along the inside of the thigh, you have been doing it right.

But I disagree that standover is a negligible part of fit; try an emergency
dismount on a steep slope facing uphill.

Re: [RBW] Saddle height and BPH

2022-12-14 Thread 'Slacky Mac' via RBW Owners Bunch

Thanks (thank you, thank you) for bringing attention to the the Catalyst 
pedal - I think it will be a godsend for me.  I deal with an injury related 
neuropathy in my left calf muscle which prevents me from doing things like 
a tippy toe on that side.  Had to sell my pristine manual ‘07 Honda S2000 
as I could no longer use the clutch safely - a tragedy!  Being able to 
incorporate more of my foot on the pedal will be wonderful as I half-foot 
my left pedal now and it is a struggle.  I measure to a 76cm saddle height 
based on PBH, but it runs closer to 70cm in actual use.  Not ideal, but 
better than siting on the couch.

With a new Sam ordered, I now think I will now request the smaller 170MM 
crank as part of the build to help balance things out.

Sure glad I found this group!

I find a more slack seat tube I run my saddle a bit lower than a steeper 
counterpart. 

Ride whatever is comfortable. Don't worry too much about stand over. French 
fit looks great.

Jay, I noticed your mention of the Pedaling Innovations Catalyst pedal. If you are using a mid-foot position on your pedals ( I do) you may need to adjust your saddle down 2-3 cm. I discovered this on my own then confirmed it with Pedaling Innovations. For this and other reasons I do not favor the PBH method of determining saddle height. It’s more a guideline than a rule.

2022-12-12 Thread Eric Daume

I'm about your same size (36"/91cm PBH), but I run a 32"/81cm saddle height
(bottom bracket center to top of my (of course) level saddle). I couldn't
imagine pedaling with my saddle 6cm lower.

When I played around with mid foot pedaling, I found I had to drop my
saddle, but less than an inch.

Re: [RBW] Saddle height and BPH

2022-12-12 Thread Eliot B


If you put the heel of your foot on the pedal and rotate it to the furthest 
point away from you, you should be just about locked out. When you then put 
the ball of your foot on the pedal like you normally ride, you will be just 
shy of full extension which should be a good ball park. You want the saddle 
as high as it will go without causing rocking in your hips or over 
extension in your legs.

Re: [RBW] Saddle height and BPH

2022-12-12 Thread Justus G

Standover is generally a non-issue and should be of limited consideration 
for fit purposes, all things being equal.

I do believe your saddle height has been very low based on the fact that I 
have an 83cm PBH and run a height of 72cm.  The Riv guidance looks to be 
within expected range.

Generally recommend dialing in saddle setback first and since yours is 
slammed back, I would recommend centering it on the rails and raising it a 
little further.  If you can sit  on the bike (with someone holding it 
upright for you) and hover your hands over the bars without engaging too 
much core strength, you are probably in a good spot with respect to saddle 
setback (and its relation to bar height).  If your weight distribution with 
the new setback leans you into the bars and puts weight on your wrists, 
then still work to do (fore, aft, tilt, relationship to bars etc.)  

Saddle height should be such that your legs come close to full extension on 
downstroke but do not lock out and does not create side to side hip 
movement (reaching for the pedals).

[RBW] Saddle height and BPH

2022-12-12 Thread Jay Lonner

I just took delivery of a new (non-Riv) bike and am dialing in the fit. I’m
a little worried that the frame is too big for me, since I only have maybe
2” standover, which seems tight for a gravel bike.

So I went out and measured the saddle height on my Hunq (which is a size
62). It came in at about 75cm. This gives me a solid fistful of seatpost.
Then I remeasured my PBH, which is 93-94 cm depending on hard I pull. For
reference, here’s the relevant page from HQ:

https://www.rivbike.com/pages/pubic-bone-height-how-to-measure-your-pbh

This suggests that based on my PBH my saddle height should be closer to 83
cm – an 8cm discrepancy. Before riding in this morning I raised my saddle
height to 79 cm, basically splitting the difference. It felt weird, which
of course it would after so many years at 75cm. But I made it in and my
feet were in full contact with the pedals without any tippytoe maneuvers.
So I guess I’ve been doing it wrong this whole time? Kind of embarrassing.
Even so, according to the Riv method my saddle height is still ~4cm lower
than my PBH would suggest.

So I guess I’m wondering about alternative ways of determining saddle
height somewhat objectively, and/or whether I should now be looking at
other variables such as a fore-aft saddle positioning, saddle angle, and
even saddle type (currently a B68, slammed back as far as it can go on a
S83, with the nose pitched up ~10 degrees or so). Other relevant factors
might be crank arm length (175mm), pedal height (Pedaling Innovations
platform pedals), and shoes (Chuck Taylors, typically). Looking for the
optimum balance of comfort, efficiency, and protecting my perineum.
