Stack & Reach of Argon 18 E-112?

I currently ride a 58cm Cervelo Dual, which has the same geometry as a 58cm P2. ( http://www.cervelo.com/bikes.aspx?bike=P22009 ) And, I’m trying to determine if I could achieve my current position on the E-112 in a size L. ( http://www.argon18bike.com/main.cfm?l=en&p=01_100&C=1&SC=14&item=E-112 )

If I did the calculations correctly, the stack & reach of the size L E-112 are 53.85cm and 42.57cm, compared to the published 55cm and 44cm for a 58cm P2 and the published 53.1cm and 42.9cm for a 56cm P2.

So, that would put the size L E-112 somewhere between a Cervelo P2 in 56 and 58. And, the size L E-112 headtube would be 2cm shorter than a 58cm P2 and the same length as a 56cm P2.

How big is Torbjorn, and how does he get away with riding such a small frame?

(Or, did I screw up the math when calculating the stack & reach of the Argon bikes?

Check out Dan’s stack and reach table. All the numbers are there.

i ride a medium size e-112, im 6-3 and change… my legs arent as long as some might think, more of a longer torso… i went for a FIST’ing ( i love the sound of that)

i tried both M and L frames, the M was way more comfy for me…

Shown below is a sample setup on a 58 dual. Then how that setup would be achieved on the Argons. This shows what changes in stem length, angle and spacers would be required to match your current bar position assuming you use the same aerobars.

Torbjorn gets away with it because $ ease the pain.

Wow…Were all of your calcs manual or do you utilize some software? That’s impressive.

algorithms worked out the old fashioned way on paper but I’ve been using that spreadsheet for a long time
.

So do you have the calculations built into the spreadsheet? Is it something you’d share? Sorry is that is a dumb question, but I’m looking for a new bike and would like something easy enough to make an apples to apples comaprison.

Bob

Wow. Thanks.

If you don’t mind doing one more comparison calculation…

With my current fit, I use the forward saddle position (78* STA) and a 120mm/-10* stem with no spacers.

If I were to use the forward saddle position on the L Argon (also 78* STA), what stem length/angle/spacer combo would I end up with to put the same bars in the same position? And, what would that do to the weight distribution?

After looking at the Stack & Reach database (Man, I wish I’d have looked at this first!), one concern I have is the front/center. The L Argon is 2.1cm shorter than my bike. Would that amount be a problem in the real world?

BTW, does the saddle height in your table take into account the BB Drop? (Is that why it’s 1cm different?)

Thanks, again.
