Setting brake or derailleur cable tension is a two-hand job that somehow requires three hands. You need one hand to hold the cable taut, one hand to tighten the pinch bolt, and ideally a third to keep the brake pads or derailleur in position. Park Tool's BT-2 Cable Stretcher solves that math by acting as the extra hand you don't have. The tool grabs the cable, pulls it tight, and locks in place with a ratcheting thumb mechanism so you can let go and focus on securing the pinch bolt.

The BT-2 works on both shift and brake cables, covering the cable jobs you'll encounter on road and mountain bikes with mechanical shifting and cable-actuated brakes. The ratcheting lock is the key feature here — squeeze the handles to pull the cable taut, and the thumb lock holds that tension without you maintaining grip pressure. That frees up both hands to work the wrench or hex key on the pinch bolt, which is where the real time savings comes in. Without a tool like this, you end up fumbling with pliers in one hand, a wrench in the other, and hoping the cable doesn't slip before the bolt is tight.

The tool body is chrome-plated heat-treated steel, and the handles have cushion grips for a solid hold even when your hands are greasy from cable lube or degreaser. If you're doing your own cable work at home, the BT-2 turns a frustrating juggling act into a controlled, one-step process. If you're a shop mechanic cycling through cable jobs all day, it just speeds up a task you're already doing dozens of times a week. The tool is made in the USA.... Read More
