Updated May-2020 Crankset weights will vary depending on size and length. Cassettes are 11-28 (or closest) We've removed bottom bracket weight as these are frame dependant.  Note: SRAM eTap component weights includes batteries because batteries all weigh the same. Note: SRAM HRD shifter weights include the cables, brake hose and caliper. Note: Di2 weights do not include wiring/junction box/battery. The reason why is because there is a host of different wire length + junction options and weight will fluctuate with setup. Note: Mechanical weights do not include cabling. Note: Disc brake weights do not include brake hose/fluid.  GRX Groupset total weight does not include cassette and chain. Choose from any appropriate 11spd/10spd option.
