Bicycle spoke that has a black spoke accent hand twisted into a bracelet. The black coil is handmade from coiling a black spoke to fit. The spokes are stainless steel and the bracelet comes in 5 sizes. Although this is an uni-sex item, this one is a great "guy" piece and I've personally worn this bracelet for years. This is a very durable and easy to wear item even while being active. !!!!!!!!!*****FOR BEST FIT*****!!!!!!!!! Choose a size that is about 1/2" or 1.3cm LARGER than the actual wrist measurement. To get your wrist measurment; Take a piece of string and wrap it around the wrist, then measure the length to convert it to the right size.
