Can i fit a rigid fork to this?

[RadNomad]

An aquaintance is the original owner of this Rocky Mountain Blizzard. He wants to fit a rigid fork, something high quality. Is there anything suitable, either RockyMtn original or some other brand? Any idea what the axle to crown length should be? Would appreciate any recommendations.
A bit tricky because it's a disc brake era bike (early naughties i think) and the majority of MTBs had front suspension by then.

Yes, looks like an F80 fork so something with an A-C of around 430-440 will give the correct sagged geometry.

(If it's 90 or 100 mm travel, just add 10 or 20 mm, A-C of the 80mm fork is 450.9mm)

The F0345 should be *almost* bang on, the F0325 is possibly slightly short.

(dependent on what travel those forks actually are!)

Re:

Yes, find out what suspension travel the frame was originally designed for.

Replace with a rigid fork also designed to fit on frames made for that travel.

Excellent, thanks very much!
