We upgraded your typical iron cable coil to a stainless steel one. It makes it vastly more challenging to rust and then finished the set in a beautiful range of technicolor coatings. The coil material is shorter in width than other standard coils, so you can achieve more elegant curves in your routing pursuits The housing includes a polyethylene inner liner and it makes the pull of your brake lever significantly lighter. Outer diameter is 5mm and you can spec 1.5mm or 1.6mm inner wires. Because of the increase of disc brake bicycles, a diversification of cable routing methods, and the usage of full length housing- we provide you a total length of 3m (a regular length is 2m typically), so there should be no necessity of extra length for your bike. Length : 3m Included: Chrome plated outer cap (4pcs)
