Yes, all Libres use a 12mm bolt up front. The Full Race (and the wider forks) also have a large hole if you want to use a 20mm bolt instead, though I believe it would need to be a custom machined bolt/stud.
Edit: Post amended. There are actually four fork widths as pointed out in the post below mine. Standard, Midi, Bigfoot Lite, and Full Bigfoot 280mm.
SavUK, yes, the flexi wide tires easily fit the Libre rims, though you will need the mid-width fork as mentioned in another post.
