Hi, this is probably a stupid question, but then that's what most of my questions are. A while back I put new handlebars (road) an aero levers on my bike. I've since found that if I'm using a lot of force on them (like climbing out of the saddle or braking hard and suddenly on a steep downhill with lots of momentum, the levers can move from side to side (never forward and back) a fair bit. Is there a way I can tighten them without removing my whole break cables? Can I just disconnect my straddle (centerpull cantilevers) pull back some cable to get it out of the way and have enough room to fit the allen wrench in there to tighten the bolt? I'd really rather not have to redo my break cables and tape job if I can avoid it, but the side to side mobility of the levers makes me a bit nervous as I'm afraid it'll expand to forward motion one day when I'm on the hoods and I'll eat pavement.
