Sturdy! At first, I was disappointed in the length of pull, but using with my front disc and rear rim brakes it worked out perfectly. I was having cable-slipping trouble with my front brake-- so bad that I soldered the cable to the brake arm. Well, diverting the additional pull force to the rear-rim brakes has solved my slipping problem, and I stop fast. All the time. I use a grip-shift for a clutch, so I don't need this... but wow, it's nice!
