MUCH safer and more effective than the old turkey/suicide levers. Easy to install, since the bands are hinged, no need to unwrap the bar, etc. Oh, and no clacking.
Only hitch with interrupter levers is that you have to use aero type brake levers that route the brake cable under the bar tape. However they are far superior to the extension levers
