this cool wall clock would look fantastic in home or office! based on my cascading bike rotor wall clock, this one only uses road bike gears which makes it a bit smaller. very easy to mount using nothing more than a small tack nail, and measures approximately 14” x 5” x1.5”. each one will vary slightly as i am using recycled materials. please specify color of hands you prefer. red, blue, lime green. if nothing is specified it will ship with blue hands.
