Long time mountain biker, but have done very little in the way of building, changing parts, etc.. always used a bike shop. I am getting ready to purchase a 2008 Cannondale Caffeine F2 with a Lefty. I have an 05 Giant Trance I am going to be selling and probably getting a a full suspension 29er....sooooo I want to build this as a a fun rider that I will ride to work and do some XC racing with. That being said I want to do a 1x setup. I want to start thinking about what I need to look at getting. I will probably be switching the rear derailleur to an XT 9 speed. I am guessing I will need to change the cassette.. I have no idea what crank it has on it.. so I will probably need a new crank with a single ring on it (what size?) What is my tool list for removing these parts and placing new. Thanks for any and all help.. hope this makes sense thank you!
