Does anyone know if the Orbea Lanza hardtail frame geometry is set up for an 80 or 100 mm fork ?

2 of the XC frames I have been looking at are for 2007 designed for 100mm travel - even though they are described as racing frames (seems to be a new trend) Commencal and Kenisis XC Pro II both recommend 100mm travel even for race set up. Kenisis said with 80mm travel the BB will sit to low to the ground.....

I like the Orbea frame because it has the longest top tube, but I cannot get any answer from them on the forks.

Thanks for any advice
