Replacing stock chromo fork with carbon

I am hoping to replace my stock 2005 Fuji Sagres fork with a Winwood Dusty cross fork. I will be having the shop do this as I don't have the tools, but would like to know if I need to take into consideration anything beyond the tube size.

The headset is a 1 1/8" integrated, and the fork has a 30mm crown race. Does it matter that the headset is integrated? Are there any other measurements I should consider before ordering? Should I replace the headset while I'm in there? Can I replace an integrated with a standard headset? Am I over-thinking this?

The bike has been upgraded in every respect aside from crank and fork. It's a lean, mean commuting machine right now, and after riding my new Fuji Cross Comp with the carbon fork, I am in love with the smoother ride. I really didn't think the difference would be that severe.

Thanks all.

integrated threadless headsets are neigh interchangeable.

I would just reuse the old headset if it isn't indexing.
no point upgrading headsets since the only thing you stand to gain are lower weights.

So the carbon crown will not present a problem? Sorry, this is part of the bike I am not familiar with.

100% overthink.

Unless the fork was built with an integrated crown (which it definitley is not), then all you have to do is swap the old crown race to the new fork and reassemble. There is nothing else to do. The type of integrated headset your Fuji has does not require anything more than the standard 1 1/8 fork that accepts a press fit crown race of the standard 1 1/8 threadless size.

Integrated headsets are the bomb.

No.

We bang on integrate headsets 36/45, 45/45 at the shop all day. Non-split races either. They work just fine with the appropriate size 1 1/8 crown size (30.1mm).

P.S I hope you have a good reason to "upgrade" to that mediocre cf fork. You have a very good chance of suffering brake chatter without excessive toe-in using that type of fork and cantilevers. We've dealt with this issue quite often at the shop on various Marinoni's/Specialized Tricross/Other cross rigs with carbon forks and cantilever brakes.

Thanks, I have read about the chatter issue. I'm not sure if it makes a difference, but I run V-brakes out of preference. Some reports are that the tension that the cable hanger puts between the stem and the fork is what may cause it. My goal is to acquire the reduced vibration from the road, not the weight. I have no business worrying about how heavy this bike is.

EDIT: The reason I'm interested in these forks is for the canti bosses. A carbon road fork will not work unless I go to road brakes, which would just add expense.

You should not only try to match the brake mounts on the new fork, you should also try to keep the same axle-crown distance and fork rake so that the handling characteristics of the bike do not change noticeably.

The fork I'm replacing is a hybrid fork, so I'm assuming longer axle/crown measurement. I don't mind the more aggressive shorter length as long as it doesn't pose a safety hazard.

I measured the existing axle to crown length at 400 mm. The Winwood is 390, so I think I can live with and actually prefer the shorter length. Thanks for all your help. I also found a Rocky Mountain cross fork for a ridiculous $55. Awaiting specs from the dealer.
