I have a 1st gen Canyon Lux Trail with a Fox 34 SC 120 fork. I’m considering over-forking to 130, with the main purpose to slacken the headtube/extend the wheelbase to make the bike a bit more stable. According to [bike-stats.de](https://bike-stats.de), that is going to slacken head (and seat) tube angles by 0.6 degrees and lengthen wheelbase by 5.4 mm, along with various other knock-on effects. My question is, if my goal is to make my bike a bit more stable and capable, is this change reasonable and worth it? The sag I run is 20% in the front and 30% in the rear (110 travel rear). Assuming I use stem length, headset spacers, and saddle position to maintain my cockpit, can I expect any noticeable difference in handling? At sag, I’d only be extending the fork length by 8 mm.
The other option I should consider is a new frame, but cost considerations favor a fork replacement rather than a frame replacement. But would I be better off with spending the extra money on the frame rather than the fork?

10mm is okay. You may not even notice the difference. But do be warned that you may not have warranty
You can just get a [tapered angle-spacer](https://reverse-components.com/en/products/05%C2%B0-angle-spacer-tapered-forks) to slacken the headtube by 0.5°. Remove 10mm of spacers under the stem and your cockpit will end up in roughly the same position.
Much cheaper than a new fork or frame.
I think you can run 15% sag in the 34sc, I would try that first. See what sag you can run in the rear too, if you can go to 25%, do it.
Modern geometry (more reach, higher stack) will give you a more stable and capable bike than 10mm of travel or 0.6 degrees on the HTA will do, in my opinion. I’d say new bike/frame or leave it as is.
Yep, lots of people do this and it’s a great way to achieve the goals your looking for.
Generally, you don’t need a new fork, just a longer air shaft.
Also, most bikes are warrantied to run an extra 10mm of travel. Contact your manufacturer to find out.
