Seismic Aeon 105mm Solid Axel Longboard Truck (Single)

Specification:

• Axel Size: 105mm
• Axel Height: 2.37" (from baseplate to axel midpoint)
• Baseplate Angle: 30º & 45º
• Reverse Kingpin (RKP)
• Sold as a singular truck (please add 2 for a full set)

Cylindrical Bearing

Cylindrical Bearing Built Directly Into Bushing-Hanger Interface – A Revolution in RKP Truck Engineering! 

• Concave channels (“races”) on bushing faces wrap around “rollers” built into hanger bushing seats.
• Patented Aeon “TrueTurn” tech forms working cylindrical bearing with no added parts. (See exploded view in the second image.)
• Centres and guides hanger rotation, in tight alignment with the pivot axis – without the downsides of support pins, spherical bearing inserts, or hanger plugs.
• Eliminates slop, and significantly stabilizes geometry even at deepest lean angles.

Advanced Control

• Beyond Barrel vs. Cone: Aeon bushings have a wide hexagonal shape and tapering sides.  Creates a smooth, intuitive resistance profile through a larger steering range.
• Tall but not too tall, for deep turns with no dive.
• Self-lubricating formula to prevent squeaking.

Lightweight and Affordable

• Elegant body sculpting and the first-ever hollow pivot channel (extending into the bushing seat area).
• Precision engineering in a moderately-priced cast design.  (CNC body parts add high cost with no guarantee of high performance.)

Precision Fit

• Custom contouring creates a mechanical lock between the Board-Side (BS) bushing and baseplate – no washer needed.
• Faced hangers for the perfect interface with inside wheel bearings.
• Top of baseplate sloped for flush contact with deck concave when drop-through-mounted. (Nut seats kept flat.)

Setup Suggestions

• For optimal traction, power, and control, we usually suggest a 45° truck at the nose and a 30° truck at the tail, with stiffer bushings at the tail than at the nose. Use two 45° trucks on symmetrical (twin-tip) decks. Use stiffer bushings if you’re heavier and/or taller than average, softer bushings if you’re lighter and/or less tall.

• For a more “surfy” (“lean”-y) feel, use Boardside and Roadside bushings of the same duro. For more precise (“turn”-y) response, use harder Boardside bushings and softer Roadside bushings – especially with trucks wedged steeper than 45°, and with DH and Fast Freeride setups using narrower hangers and split geometry. (Example: blue 90A bushing Boardside and yellow 82A bushing Roadside on your FRONT truck.)

Axle Height

• 30° Model: 60.4mm / 2.38 inches from baseplate bottom to axle midpoint (39.7mm / 1.56 inches when hanger is flipped)
• 45° Model: 60.3mm / 2.37 inches from baseplate bottom to axle midpoint (34.8mm / 1.37 inches when hanger is flipped)

Axle Offset (Rake)

• 9.0mm / 0.35 inches (both 30° and 45° models)

Roll Center

• 30° Model: 10.4mm / 0.41 inches above axle midpoint (same distance below axle midpoint when hanger is flipped)
• 45° Model: 12.7mm / 0.50 inches above axle midpoint (same distance below axle midpoint when hanger is flipped)

More Axle Offset (or Rake) pushes the Roll Center higher (towards the deck), resulting in quicker lean response and better wheel traction. Less Axle Offset (or Rake) leaves the Roll Center lower (near the axles), resulting in better lean control and stability.

Sold As An Individual Truck - This allows for greater customisability of your board by mix and matching colours and baseplate angles.
