So I have the straight handlebars for my fixed gear, like the small ones for going through traffic or whatever, and I like them, but I kind of want to get a pair of bullhorns.I have both rear and front brakes too. If I got the bullhorns would I need to get new like longer brake cables or something? I like my short handlebars, but I want to try bullhorns since I don't really ride between cars or anything and bullhorns seem neat.
Also, secondary question, are bullhorns still good for road riding? I know they're good for climbing and stuff, but would you suggest it for biking in light to medium traffic?

Thank you so much for your help.
