Just got first track bike - Mercier Kilo TT. Ok, so it's not the best but I like the frame and love the woman who got it for me! I can't find out what kind of headset or size I need so I can replace it. I also want to replace stem (quill type) but I don't know the diameter that'll work - I do know I want a Zero degree 110mm but what diameter?. I checked the specs on Bikesdirect but got nowhere. They only say quill for the stem and don't tell me exactly what size or type headset they use. I also need to replace the BB as the one on there is "splinned" whatever that means and most cranksets need a tapered square? Would appreciate any suggestions and help. I could go to a store but rather do it myself.
