Handlebar Grip - Dutch Paddle
Made in Holland, where they ride a lot of bikes and rarely lose their grip. Rubbery, grippy, 110mm long (that's about normal). The paddle part goes on the inside of the bar, and feels best when you angle it up about 30 to 40 degrees.
To mount the grip, squirt some Purel on the bar, rub it around, and go for it.
They fit Albatross, Bosco, Choco, and every city bike or mountain bike handlebar ever made in the last 120 years.
