Hello
I need your help. I plan slowly to build my new 29" hardtail bike but i have a query about a bike fit that i have done in the past.My query is, if the given of the bike fitting, geometry and numbers, can be used to find, the right frame size and geometry, for me on 29" wheels?
Thanks in advance.

The wheel size isn't important when it comes to fitting the individual on a bike (other than physically checking that they don't get in the way at all if they're bigger than you are used to). The important thing is being able to get all the contact points where you want them, hence reach/stack/BB height measurements are all quite important and can be used to judge suitability of one frame or another for your own purposes, within reason.

Reach and stack are important for standing size. ETT & stack for seated.

For me I'm fussy with stack height- as I don't like a high front end. Most of my bikes have neg rise stems & slammed.

Best bet is compare with some bikes you are currently riding.

The given stack is 46.9cm and the reach plus stem is 48.8cm. My last bike was a cube fs ams 100, so i think i can't compare is a different type of bike. Also how can we decrease the stack, to assume with a negative stem?
