thanks in advance

You need to match up the following
1/ Steerer diameter (almost certainly plain 1 1/8th on your DB)
2/ Steerer length (as long as is required with no spacers as a minimum).
3/ axle to crown (race) length, run no more than 20mm less than your current forks.

And make sure it has the correct brake mounts.

I’m converting a Genesis Core 20 to a lighter commuter bike. I want to replace the 120mm Tora 289’s with a rigid cromoly fork, saving over 1kg. I’m not sure what a2c to go for. The current Tora fork has an un-sagged a2c of 500mm.
Salsa do several cromoly forks from 445mm to 483mm. Some 29er and some 26er, I’m guessing the important measurement is the a2c but do I need to consider the rake also.

445mm is too low, 475'ish will be better for a 120mm fork.

That's what I suspected, sounds as though I'd be better off with a 29er short travel corrected option.
