The 27.5" Killer Quad is back, and it's a testament to a legendary SE Quadangle frame design. The Killer Quad is equipped with a smooth Microshift 1x10 drivetrain, giving you a wide range of gears for every session. The Shimano MT200 hydraulic disc brake provide all the stopping power you need. New for this year, the double-wall rims and sealed bearing hubs roll on 27.5" x 2.5" Maxxis Hookworm tires for a secure grip and smooth roll. The flangeless Mushroom Wing grips will keep your hands comfortable, and the new SE Captive seat provides a secure and comfortable feel. The bike is finished off with a quick-release seat clamp for easy adjustments, and water bottle mounts were also added to the frame this year. 

The bike features a 6061 aluminum frame with a single downtube Killer Quad design, an internally machined integrated head tube, looptail rear end, fixed dropouts, water‑bottle mounts, a 73mm Euro bottom bracket, 135mm spaced dropouts, disc‑brake tabs, and a removable derailleur hanger. The Landing Gear fork is full chromoly with a 419mm axle‑to‑crown height, 29mm offset, and 110mm spaced dropouts.

It’s equipped with SE Racing 170mm forged‑alloy 2‑piece cranks with pedal‑boss inserts, a 32T narrow‑wide alloy chainring, and an external sealed Euro bottom bracket with a 24mm hollow‑alloy spindle. Pedals are X‑Pedos with a low‑profile platform and removable pins.

Shifting is handled by a MicroShift XLE 1×10 drivetrain, including the RD‑M61S short‑cage rear derailleur and Xpress SL‑M850‑R shifter with sealed bearings and an alloy lever. The MicroShift XLE 11–32T cassette is paired with a KMC X10 chain.

The wheelset includes sealed‑bearing alloy 36H nutted hubs (135mm rear, 110mm front), double‑wall rims with metal eyelets, stainless spokes, and a 10‑speed 11–32T cassette. Tires are Maxxis Hookworm 27.5×2.5" (60 TPI) front and rear.

Braking is provided by a Shimano MT200 hydraulic disc system, featuring dual‑piston calipers, One‑Way Bleeding, and a 160mm rear rotor. The cockpit includes an FSA sealed‑bearing integrated headset, Big Honkin’ chromoly cruiser bars (31" × 7", 12° backsweep, 2° upsweep), and a retro alloy top‑load stem with engraved SE logos and 55mm reach. Grips are SE Racing flangeless Mushroom Wing grips with rubber end plugs.

The bike comes with the SE Captive seat featuring a concave comfort design and integrated bottle‑opener brace, a 27.2mm micro‑adjust alloy seatpost, and a 31.8mm quick‑release seat clamp. Accessories include alloy valve caps, water‑bottle mounts, and a removable derailleur hanger. Wheel size: 27.5".
