SRAM XG-1391 XPLR E1 cassette – a 13-speed 10-46T cassette for gravel bikes, developed alongside the RED XPLR drivetrain.
Key features:
Range: 10-46T – from fast road tempo to slow technical climbs, all on a single chainring.
Speeds: 13 – the extra cog means smaller jumps between gears than on 12-speed cassettes.
Freehub: Mounts on an XDR driver body – check that your rear hub has one.
Series: XPLR E1 – SRAM's gravel line, matched to XPLR derailleurs and chains.
Summary:
The cassette decides whether you ride up the climb or push. A 10-46T spread over 13 speeds is one of the widest ranges available today on a 1x gravel setup.
