Laser-etched graphics provide a distinctive finishing touch.  Cold-forged 6061 aluminium crank arms mean that the Gossamer Tandem crankset has the strength and reliability that tandem riders look for. A spacer system allows the chainline to be adjusted over a 10mm range, allowing the timing chain to be perfectly aligned.  The rear chainset has a wide-range 52/39/30 triple configuration on the drive-side and a 42T ring opposite for the crossover drive.
