i've recently aquired an 80mm travel suspension fork - marzzochi z2 bam

so now i've got to decide on a frame to put it in
how will bike handling be effected by using a frame not intended for said fork ?

considering using :
rigid frame
hardtail meant for 100mm travel

so either going longer or shorter , what kinds of handling change will there be each way/whats less detrimental ?

thanks


p.s.
anyone know specs on a Soma Groove?
2011 (most recent) model wants a 80mm travel , but a 2006 i was looking at seller claims 100mm
