Just wanted to know if the geometry listed on the Niner site for the R.I.P 9 is accurate? I know I'm thinking quite a ways in advance, but, just trying to figure out what size I should probably get when I finally save up the cash for it. I right now ride a 22"/XL Trance w/ a 120mm stem and setback post, TT measurement as far as I can determine is 24.5" max which is over 1/4" shorter than their advertised geometry charts say. Right now I measure 36.75" from rear of saddle to front of stem. I'm 6'2 1/4" w/ a 35" inseam.

There is an easy test for a bike company's geometry:Call them up, then ask them this question:

If you have a right triangle with a 3 inch long side and a 4 inch long side, how long is the hypotenuse?

If their answer is anywhere around 5 inches, they're geometry is pretty good. :thumbsup:

"around 5 inches?" :skep: If I'd given an answer like that on a vector exam I'd have flunked.

"around 5 inches" fer cryin out loud.

You have to consider manufacturing tolerances.

Not sure if that's a question or statement :confused: but either way yes I take the Effective TT measurement from the centre of the HT to the centre of the seattube along a horizontal plane, using the standard fork which the bike was designed for.

Their measurements for Effective Top Tube are taken from the center of the HT to the center of the post along a horizontal. You aren't taking measements from the same place.
Oh and I almost forgot to say thanks for all the helpful replies.

Okay then. You confused me because you said "Right now I measure 36.75" from rear of saddle to front of stem.". So I thought you were doing it wrong. Guess not. :p

Just gave that measurement as an idea of cockpit length/setup.
