[RBW] Re: Anyone else have trouble measuring their PBH?
Hi all: Thanks for the good ideas and thoughts. I think that in trying to pull up on the paint sticks, I was actually crouching down/leaning forward a bit, and I also think that the tape measure was off-center.

Does anyone else just measure their existing saddle height and add 10? Seems way simpler, if you are already a bike rider. I thought this was how everyone determined their PBH. Or, you can use the stick and tape measure, and when you get a reading that equals your saddle height plus 10, go with that. :-) -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Re: [RBW] Re: Anyone else have trouble measuring their PBH?
I use a book, like some coffee-table picture book (Golden Age of ... by Jan Heine would work well if it were thicker ...) but thick enough to simulate the pressure of a saddle - maybe a 2x4 with a rounded top would be good. It needs to be pushed up pretty hard, pressing against the pelvic bones. It also needs to keep a horizontal top sufrace, so the tape-measure measures the real height back in there. One easy way to do this is to stand with your back against the wall while your assistant positions the book, then you hold the book while the helper measures and reads it out. Using a book or a 2x4 eliminates pain due to a ridge pressing in, and flexing of the stick. Or just go to a bike shop with a Fit Kit and see if they'll let you self measure on their setup - it's a quick job, they should not charge you, especially if not busy. Carefully positioning all your dangly parts to make sure nothing gets caught on the book and nothing hurts is expected. Starting out by wearing bike shorts is also a real good idea, to hold it in and to eliminate seams.

Yes, pull up with force and off to the side. The highest value of several attempts will be the closest to your true PBH. You can't measure too high.

[RBW] Re: Anyone else have trouble measuring their PBH?
Borrow a framing square and place it against a wall before pulling it upwards. As long as the wall to floor joint is square and you get the square past your junk you can now easily measure your true PBH with a tape measure. Just measure the distance between the top of the square and the floor.

[RBW] Re: Anyone else have trouble measuring their PBH?
If you are buying an expanded frame model like the Sam Hillborne you don't have to be so accurate because each frame size fits a wide range of PBHs. I think the 52 cm Sam Hillborne fits 78PBH84.

Re: [RBW] Re: Anyone else have trouble measuring their PBH?
That is the best idea I have ever heard of for measuring the PBH on your own. The framing square should be long enough for you to get accurate measurements. You can get an assistant to just mark a wall with a pencil were you are squaring and measure from the wall to get your PBH. Good idea. K.

A large book does the same thing, and will be more comfortable, hence easier to shove up there.

Re: [RBW] Re: Anyone else have trouble measuring their PBH?
But I think the value of the framing square is that it's so thin, it kind of gets right up in there. Hopefully, you're not doing this often enough or long enough that comfort is big issue...

Re: [RBW] Re: Anyone else have trouble measuring their PBH?
Yes, I can see that it might, but I think the real requirement is to come as close as possible to getting the maximum height of the ischial tuberosities above the foot sole. They are a bit lower than some other anatomical features of the pelvis, I think. And to compress the intervening tissue as it would be on a saddle. At least that's my interpretation. I haven't had any formal fitting training. Plus it may not matter, if we fine-tune out saddle heights on the road based on leg extension, knee pressure and comfort, and pelvic rocking.

[RBW] Re: Anyone else have trouble measuring their PBH?
A 4 to 5 cm discrepancy is a very large one. I would reconfirm the measurement process with your fine assistant and double-check the measuring tape and conversion calculation (if any). Other than that, wear thin and loose pants and yank that stick up severe enough that it resembles you sitting on your saddle. It should feel uncomfortable.
