FatBike Borealis Echo

Borealis Echo X0X9

Our X0X9 offering is an excellent choice for riders who prefer the widest gear range out there: a full 2×10 set up. Sram X9 shifters paired with an X0 Type 2 rear derailleur allow for smooth shifting in the muddiest of conditions. A full RaceFace cockpit and mechanical BB7 brakes make for a solid, low-maintenance machine for perhaps the widest array of riding types out there.
