Replace suspension fork with a rigid fork
Is it ok to replace a suspension fork on my mountain bike with a rigid one? I was given an older GT aluminum mountain bike with a worn Manitou 3 suspension fork. I would like to spend as little as possible to get it going so I was thinking of replacing the suspension fork with a cheap rigid one. Would this be ok? If so, does the rigid fork need to have any rake or is a straight one ok. I am thinking I would need some rake even though the current suspension fork is just straight. Anything else I should consider?
