Changing fork rake on a 'gravel' bike?
Hi!
I have a 2018 giant Tcx advanced sx (size M/L) that's currently using a fork from a 2015 tcx because it was full carbon and lighter.
I'm starting to wade more into the adventure side of things and want a fork with bottle/accessory mounts. I've found something promising that's got a rake of 45 vs the 50 my fork came with. I'm just trying to figure out if it's worth trying out.
I also ride this bike on the road a lot, but have separate wheels. The tires on said wheels are narrower which should decrease the trail a bit for more spirited riding, right?
Any advice appreciated!

Hey bud. The reduced rake will increase trail, by an amount that would probably be noticeable. But it will also shorten the wheelbase a bit. Between that and relatively narrow tires, the effect on handling would probably be relatively small. I don’t think it would do any harm, probably worth trying. I would also compare the axle to crown of the two forks, if they’re different that could have an effect as well.
I think the axle to crown measurement between the two forks is within 5-6mm. I think they're the same, but I'm measuring with a tape and the ATC measurement for the new fork is on the box.
Also, I'm going to be using 32's or so for the road, but 35-40's on more gravel-ish rides. So when riding primarily on the road, the trail will be lower since the tires will be slightly narrower, although not by much. I'm guessing that this bike was designed with 32-34mm tires in mind because cross.
