Would changing a 100mm front suspension fork to a 140mm compromise the head tube?
I'm considering of changing my 100mm front suspension to a 140mm.
Riding aerodynamics aside, would the increased height of a 140mm fork compromise the strength and integrity of the head tube?
Or is the change minimal enough to not have an effect?
just changing it and riding it as you are now won't comprimise any integrity. If you are doing it to change your riding from XC to something more hardcore then maybe the bike wasn't designed for it. It will slack your head tube and seat tube angles by more than 2 degrees as well as lift your bottom bracket.
It will look almost as relaxed as a dutch commuter bike.

What are you measuring? fork dropout spreads are 100mm,, only a Pugsly endomorphic fork is wider.
Not width, but length. Looking to increase the fork length with the goal of increasing my bikes height by 4-5 cms at the handlebars.

I've spoken to my LBS and they have my current bike geometry and my measurements and are going to try to find me a match, possibly in a 29er.
If they don't find one, then i'll look at the custom fit route.
Adding a higher angled stem and/or riser bar greater than what I already have just doesnt make me comfortable, and neither does changing the fork from 100mm to 140mm.
Many, many thanks again folks for all your inputs, it has greatly helped!
I'll let you know how it works out!
