Saddle height

[IdeJongh]

No not angle of the seat tube.  When you set your bike up your ensure that the seat is as level as possible, but as the back compresses the frame slightly rotates backward around the bottom pivot...or does it...hmmm....maybe I should get back to work as well...

Idejongh, you should take everything in account when you set up your bike. When you sit on it, and it sags 20mm obviously will the nose of the seat rise a bit. If it does not affect your comfort then keep it, otherwise drop the nose. You don't set up a bike by looking at it, you sit and fit and see what works.

Mampara, makes sense, thx.

If the back sags the front should sag as well

Depends on setup. Maybe you run the back softer then the front.

inner leg measurement(in cm) from bottom of heel to your guch(not sure on spelling) and multiply that by 0.885. you should get a pretty close measurement of your correct seat height

it is multiplied by 0.883, this is one of the formulas that I have found leaves my saddle too high, especially for MTBing for road it might be better.

ja generally i do lower it between 2 & 3 cm after that because i can see it is a bit to high...but i've sent off HUNDREDS of HAPPY CUSTOMERS using that formula so i'm sticking to it

Bike setup has different effects on different individuals. The standard rule of thumb about height, length and distance is just that - rule of thumb. It's a good starting point but just because the rule says the (seat height =  inside seam - street number + your age) does not mean it will be 100% for everybody. These measurements are there to work from towards something that makes sense for the individual. Sean Yates for instance didn't give a crap about science of bike setup and it always looked like he was riding a kiddies bike.
