From Simworks:
We changed the iron outer cable coil to a stainless steel one and it makes more difficult to rust.
It includes polyethylene inner liner and it makes the pull of brake lever much lighter.
The outer diameter is 4mm and you can use 1.2mm inner wire.
Because of the increase of disk brake bicycles, a diversification of cable handling, and the usage of full outer cable, we provide you a total length of 3m (a regular length is 2m mostly), so there should be no necessity of extra length for your bike.
Length : 3m
Accessory : Resin made outer cap (4pcs)
*This stainless outer cable for shift is a different from a regular conduit type (a type of forming wires in straight vertical line) and it is coil forming. Coil form has an advantage of its flexibility, but a conduit type has less stroke loss. If you require a severe racing spec by using 10 to 11 gears, then we can’t recommend you to use this cable.
