1. ## Uzzi Geometry

Hello everyone,

I'm planning on upgrading my 2005 Kona Stab Garbanzo with a new Uzzi and while looking at Uzzi's geometry on Intense's website came across a strange number... I emailed Intense but had no answer so I decided to post it here to see if someone could help me out!

In Intense's website it is stated that Uzzi's geometry is measured with a "180mm fork AC 575mm". However, Fox states their AC height for the 36 180mm is 565.3 mm (2013 Product Specifications). Their 203mm 40 fork is 571.2 mm. For a Rock Shox Boxxer with 200mm the measured axle to crown height is 568mm.

These numbers will of course affect the bike's actual geometry.

If the information on Intense's website is correct and according to my drawings and calculations (simple trigonometry on a triangle drawn from rear axle -> from axle -> top of the forks crown, starting from a 575mm axle to crown height and stated geometry), with a Fox 36 180mm the head angle would increase from 65 to 65,4 degrees and the wheelbase would decrease from 46" to 45,8385827" (assuming a medium frame). Even with the Fox 40 the wheelbase would be around 45,9" and the head angle would still be 65,2 degrees.

The difference is numerically pretty small, but if we take a look at other bikes and even at other Intense frames head angles do not vary much more than 1 or 2 degrees for example, so I'm guessing these are significant changes.

So can anyone confirm these numbers? What do you think?

Thank you!

Caio.

2. Nearly all manufacturers do this. Invent an axle crown length to suit the numbers they want. In reality the stated angles probably are not accurate anyway. Often real world measurements are different.
Remember though its not static measurements that determine handling, it's dynamic, ie the angles when your riding and producing sag etc.
