If you're looking to replace your cables then Jagwire's stainless cables are, in our opinion, the best option. We offer them here because finding high quality, longer length cables can be a challenge in some bike shops.
Most recumbent bikes/trikes can use a standard length (2300mm) cable for the front shifter/derailleur connection. Rear cable length depends on the cable routing of each bike. Most recumbents we see need only a tandem length (3100mm) cable to make the connection. Please measure your current cables to ensure the proper length before ordering.
The cable ends are Shimano/SRAM compatible. They will not fit Campagnolo and some Microshift systems.
