Hello All,

Long time voyeur, first time poster...

I have a 1995 Bianchi Grizzly RC frame – no fork. Per BikePedia, it originally had a Marzocchi XC-600 suspension fork on it, which had a 51mm travel.
I would love to make this into a rigid fork commuter but I don’t know how to do the math to figure out what distance I need from the crown race to axel, and I’m not sure where/how a forks rake figures into the equation. Any advice/suggested forks, would be greatly appreciated.
