On my trek 3700D 2013 model I am going full rigid with a surly 1x1 100mm suspension corrected fork

my current fork axel to crown is 481mm

the new fork is going to be 453mm

difference = 28mm

may be we minus 20mm SAG, still a difference of 8mm..Just wanted to check if anyone has tried a shorter fork on this bike,
also, want to knw if this shortfall is ok..

bike radar says they could have easily gone with a shorter fork on this bike...their review Trek 3700 Disc review - BikeRadar

need as many opinions as possible..

Thnx in advance..
