Hey mate. These are Rock Shox Argyle RCT which are set to 120mm (you can do this by adding/ removing travel spacers) I believe the Howlers originally came with 110mm of travel up front back in 2007-2008. I have run the bike with 100mm forks (felt a bit low) and 140mm (felt a bit clumsy) so the 120mm feels just right for me! If you are on a budget, I would look at a used pair of old style U-turn Rock Shox Pikes. You can set the travel externally from 95mm to 140mm of travel, so you can easily pick what suits you best! Hope that helps!
