I have an older Salsa Casseroll that I use as my commuter and rain bike. I'm looking to replace the fork and thought about moving from the long reach to disc. Below Ive posted the current fork and the one I'm looking to move to. How would the differences in the replacement fork affect the handling of the current bike(salsa Casseroll 53cm mustard)

Thanks!

The replacement Soma fork will slacken the head tube angle, thereby increasing trail and raising the bottom bracket. A 10mm difference in axle to crown distance will alter head tube angle by ~.55 degrees, so you're looking at ~.6 degrees less HTA. Whether you will feel adversely affected can not be predicted. Some riders are sensitive, others not, and most riders become accustomed to changes quickly. It would help to know what the current head tube angle is, and the intended tire size. The numbers can be entered here https://yojimg.net/bike/web_tools/trailcalc.php to see the changes to trail between the current fork & new fork. In general, slack head tube with medium/high trail is good for stability over gravel, and at high speed in a straight line.

For my bike (not a Salsa) I chose a Surly Disc Trucker Fork for 26inch wheels, with 376mm A/C, for its tire and disc clearance, plus contribution to desired geometry. It steepened the head tube angle, dropped the BB some, and lowered trail. I found the change to be beneficial.

Stock 72.5 HTA and 45 rake is 6.00 cm trail.

Longer fork as a guess 72 HTA and 44 rake is 6.42 cm trail.

So you would slow down your steering, but only you can say whether you would notice or not.
