My trek 8000 has fast geometry. It comes with a straight bar 630mm wide which is way too wide. I kinda want to bring myself up a little bit. Im looking for a riser bar under $100.00. It has to be lite but responsibly lite because im 240 lbs. Im not knowledgable about the dimensions I might need. Whats a good brand and should I get alloy or carbon? My bike is black, red ,white so you dont recommend a pink one. Can you pros help an old dude out?
