Help needed on adjusting hardtail Geometry

[Dirt Tracker]

Wondering if I can get some opinions on a new frame I'm getting and how the geo might change with some decisions and equipment I'm planning on building it up with. 

 

Frame is an 2018 Orange P7 with the following geometry: 

 

- HA: 66.5

- Seat Angle: 74

- TT: 622

- Effective TT: 620

- BB from ground: 310

- Chainstay: 445

- Wheelbase: 1181

- Reach: 434

- Stack: 648

 

Recommended Fork: 130mm / Guessing it's a 51mm offset

 

What I'm planning on using with this is:

- Fork: 140mm / 46mm offset

- Cranks: 165mm

 

Things that are going around my head on this are: 

- I know that the HTA will steepen in sag but will that be offset with the longer fork I'm planning on running?

- I'm looking at running a 140 instead of a 130 on this hardtail as I really like that length and tend to have my forks set up to run a little deeper with a lot more ramp up. 

- What will that trade off do to the BB height?

 

Finally I was thinking of getting a Works Components angle offset headset to slacken it out a little as they are pretty well prices but they come in 1, 1.5 and 2 degree options and they use double external cups. I'm getting really confused with how everything is going to wash up in the end. 

 

I know there are some people on better pay grades than me that will know this stuff so I am hoping they will give me some direction. Half of me thinks just strap it all together, forget the headset and ride it as I'm not skilled enough to notice I'm running a flat so good luck.

Bingo!!

The 140mm fork will slacker your HA and SA by approximately 0,5deg. But if you are running more sag, the effect will he negated.

 

One of the smarter guys can comment on offset.

 

Angleset will obviously slacken the HA, and bring your handlebar back slightly. Unless you want a really slack HA I wouldn't bother.

 

So just rung what you brung, it will be lekker.

Words of the wise. Thank you.

 

Too much to over think for sure. I'm very much of the 'buy it because you liked the look of it. Ride it. Like it - keep it. Don't like it - sell it. Could be awesome for someone else' school of thought.

 

No idea why I started to worry about all these things now. I blame the geo thread. Just read back my post and stopped at 66.5. Seems good, strap on a fork. Delete the rest.
