ATTACK UPGRADE CRANK
ATTACK cranks have been optimized and upgraded for half a year, and finally presented to buyers is this upgraded version, in order to minimize weight and retain the hardness and durability, the full set of cranks are made of 7075 material, the cranks are made of 7075 high-quality aluminum alloy and CNC hollowing process, and the cranks are added to four reinforced support body, completely ensure the durability of the cranks

Upgrade advantage 1
The new model is thicker and larger in appearance, with a stronger sense of visual dimension.
The old ATTACK crank is made of 6061, the new ATTACK is made of 7075 and uses CNC hollowing process.
Upgrade advantage 2
The installation of the crank is upgraded with a large screw tensioning structure, and the addition of M6 screws for side locking, compared to the old straight locking structure, the new one is more conducive to installation and maintenance adjustments.
Upgrade advantage 3
The old ATTACK used a 24mm shaft with six-sided mounting and locking, while the new ATTACK uses a DUB hub mounting and locking. The new hub structure allows the shaft and crank leg to bite more tightly, so even after long hours of use, there is no crank rattling.
The DUB axle is large enough to make the power feel more direct, and the advantages of the DUB axle can be best reflected in high power output.
Upgrade advantage 4
The new crank is cosmetically larger, wider and thicker than the old one, but the skeleton design does not add much weight.
The side thickness of the new crank is 15mm, and the maximum frontal thickness is 42mm, which is a direct increase of 40% in pedal rigidity.
The four reinforcement bars on the inside are arranged side by side in an X, which plays an overall reinforcing and stiffening role from a mechanical point of view.

Road cyclocross/gravel bike crankset
Features:Ultra-light Anti-rust Durable Hard
CNC hollow design, and do to strengthen the treatment, by lifting 1800N 100,000 times
Spline shaft design, 1:1 fitment, tighter installation, easier to power up when riding
7075 aluminum alloy, DUB shaft, reduce weight while improving the hardness of the axis, so that the power transmission is more direct when riding, to improve riding efficiency
Use M6 screws for locking (torque 6N)
Axis locking screw using M18 screw for locking (torque 5-7N)
