Hey guys. Im currently in the process of building up an older Jamis komodo 1. I want to say the bike is from around 2009-2010. I bought the bike of craigslist on impulse and decided to build it up a little. It appears to come stock with a 1.5inch head tube that is then reduced to run the 1 1/8 fork that came stock on it(RST Launch). I want to run a manitou circus expert fork with a tapered steer tube(130MM Travel) but I am unsure of what lower headset to purchase. Can anyone out there steer me in the right direction? Im pretty new to building bikes and I am pretty hands on but the amount of lower headset options was a little overwhelming for a newbie such as myself. I plan on having my lbs press the headset in assuming I am on the right track.
