SRAMâs single-ring drivetrain campaign is now in its final front with the launch of the new Force 1 and Rival 1 groupsets. Aimed at road, cyclocross, gravel, and adventure riders â as well as triathletes â SRAM says the new groupsetsâ one-handed, sequential shifter operation will be more reliable, simpler to use, and more elegant than conventional two-ring drivetrains while still offering sufficient range for most users.
The new Force 1 and Rival 1 groupsets are essentially slight variations of the current two-chainring Force 22 and Rival 22 groups with the only modifications coming from the rear derailleur and chainrings. The crankarms and spiders are carried over (albeit with different graphics), and the left-hand DoubleTap levers are identical to their 2x cousins aside from the removed shifter internals. As before, there will be lever options for the same cable actuated and hydraulic brakes.

SRAM's new Rival 1 and Force 1 groupsets are in essence, slight variations of existing bits that now cater to a whole new audience
The Rival 1 bits are all new but to reflect the groupsetâs newly broadened target audience, Force 1 just has a new official description; it's the same as the Force CX1 group that SRAM debuted last year. Functionally, Rival 1 and Force 1 are identical but the former will be slightly heavier thanks to a few material differences such as aluminium rather than carbon fibre brake and shift lever blades. The cranks will also be substantially heavier given the solid-forged aluminium instead of carbon fibre arms, and Force 1 will have a wider range of chainring options.
The new Force 1 and Rival 1 rear derailleurs are both heavily based on the XX1/X01/X1 mountain bike changers with the majority of the pieces essentially shared between them, such as the straight-parallelogram body, the 12-tooth narrow-wide pulleys, and the hugely offset upper pulley required to properly track wide-range cassettes. The medium-length cage option will handle up to a 36-tooth cassette sprocket while the long-cage one will accommodate SRAMâs ultra-wide 10-42T clusters. In either case, the cable pulley used on the mountain bike rear derailleurs has been replaced with a barrel adjuster and the housing entry point has been modified to better work with typical road frame cable routing.
