Connex chains are compatible with all drive systems: Narrow and lightweight for racing bikes, durablewear and corrosion resistant for mountain bikes. Chains for bicycles with a narrow hub gear system are offered as well as chains for hub gears with wider cogs, BMX bikes and single-speeds. To ensure outstanding handling and shifting performance, as well as long life, we only use premium raw materials and coatings for all our bicycle chains. Hollow pins make the top models of the 10 and 9-speed series, extremely lightweight - e.g. the 10s1 weighs only 260g/110 links. We have mapped the chains according to drive systems and bicycle types so that you are able to find the Connex model that fits best to your needs.
