Does this work?

The nc30 forks and brakes are better than the ones on my nc23 I imaginefor sure so considering if they can be changed out for NC30 stuff easily? I am putting nc35 front on my nc30 so these will become surplus for now.

Anyone done this and can let me know what is involved if so?

IIRC the lengths are different but you can swap lowers to get the better brakes.

From memory NC23 forks are much longer than nc30 ones

will leave the 23 forks as they are then for now. Just thought it would be a cheap upgrade as have the 30 forks anyway. Don't want to split them up just fr the lowers though.

The racetech gold valve emulators that Rick O sells for early NC30 forks fit the NC23 forks + new springs is a good upgrade
