Description
At a Glance
  • Fast and agile short travel full sus 29er; perfect for mixed terrain and day long epics
  • Frame: Sonder Cortex 120 mm travel, hand-welded 6061 double butted aluminium
  • Fork: Rockshox Recon RL Silver, 130 mm travel
  • Rear Shock: Rockshox Deluxe Select+
  • Groupset: SRAM SX Eagle, 1x12
  • Seat Post: Love Mud Membar, 31.6 mm, 400 mm
  • Wheelset: Love Mud Hobo 29er
  • Up to date geometry for trail bike agility and enduro bike stability

Fast and agile, Cortex is for epic days over mixed terrain. It comes alive on long technical descents with 120 mm rear travel, big wheels and a stiff responsive frame.With bang up to date geometry, Cortex is confidence inspiring with a playful character. Stand up and mash on the pedals out of turns, manual sections of trail and pop off tree stumps, rocks and roots. Smash out short and loose technical climbs, flat out descents and tight techy singletrack sections. The harder you push the bigger you grin.

Cortex frameset is hand-welded from 6061 double butted aluminium with a tapered ovalised top-tube and large section down-tube for a stiff chassis with just enough compliance to get you out of trouble. 66 head angle, 74.5 seat tube angle, 40 mm bottom bracket drop and a 465 mm reach (size large). Cortex’s dialed in geometry and 2.6” tyre clearance offers a comfortable and efficient climbing position for big miles and a stable, spirited platform for smashing up descents.

Why SX? SRAM Eagle drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. Its 1x drivetrain is a solution that is built to be lightweight, strong and intuitive, with the gear range to ride on any terrain. SX Eagle provides the same Eagle performance benefits as NX Eagle, but at a lower price point. The main differences stem from the choice of materials and finish options, but functionally SX is fully compatible with SRAMs Eagle groupset.

Geometry and Sizing

Sizing

It is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height. Generally we recommend:
Small
Riders between 5ft 2in and 5ft 7in
Medium
Riders between 5ft 6in and 5ft 10in
Large
Riders between 5ft 9in and 6ft 2in
X-Large
Riders of 6ft 2in +
