The M47 Arrow series are constructed using multiple layers of high modulus carbon fiber at various angles to achieve the perfect balance of strength, longitudinal stiffness and torsional stiffness while maintaining minimum mass. They have a narrow diameter resulting in less aerodynamic and hydraulic drag than our standard shafts. Additionally, decreased mass results in decreased rotational inertia allowing for higher stroke rates. These are the lightest rowing oars produced by Croker, and are the lightest rowing shafts in the world. All Arrows are fitted with the newly designed Arrow rowing blade.
The M4 Full Carbon series are constructed using multiple layers of standard modulus carbon fiber to achieve a balance between maximal strength and minimal mass - the 100% carbon shaft exhibits a clean and crisp catch. Prior to the development of the Arrow series, the M4 series were the lightest oars available with the lowest rotational inertia.
The M2 Superlight series are constructed using a combinaton of unidirectional and woven carbon fiber. The result is a good balance of strength and light weight. Although heavier than M47 and M4 series, the M2 series remain amongst the lightest rowing oars available.
The new Arrow rowing blade is the latest computer designed blade, specifically designed for use with the new M47 Arrow series shafts. They feature FISA minimum blade thickness along the edges and 3D curvature through the body resulting in excellent hydrodynamic efficiency and grip in the water. The Arrow blade takes the clean entry and exit that Croker blades are well known for to a new level.
Note: Tne new Arrow rowing blade is only available on the M47 Arrow series shafts and are in limited supply.
Since its introduction, the Slick blade has undergone several modifications over time and is now available with closed edges, improving the durability and overall performance of the blade.
The low volume blade enters the water quickly and quietly and floats low in the water. The longitudinal curvature is perpendicular to the tip and in-line with the flow of water. It has a constant pitch across the tip and all lines parallel to the tip. The gentle asymmetric curvature of the blade ensures a clean release from the water with every stroke. Slicks are visibly cleaner than other blades. They do not exhibit any negative tendencies during recovery or in bad weather.
Since its introduction it has been extremely successful at all levels of rowing.
Note: The Slick blade is available on all M4 Full Carbon and M2 Superlight shafts and can be cut down upon request.
All Croker oars are fitted with a copolymer, interlocking injection moulded sleeve and button system. NOTE: Magik oarlocks are not recommended for use with Croker sleeves.
The Mk3 sleeve is the standard sleeve used on all Croker rowing oars. It features a snap together interlocking clip system with only two flat surfaces. The asymmetric design reduces the distance between the shaft and the face of the oarlock resulting in improved performance. The geometry provides excellent stability both on the square and the feather.
Note: The Mk3 sleeve fits all rowing shafts (M47, M4, M2).
The original Mk1 standard symmetric sleeve comes in two parts: the sleeve body and the wear plate. The inboard measurements are calibrated on the back of the wear plate. The geometry of the sleeve, provides excellent stability both on the square and the feather. The wear plates can be replaced as required without removing the sleeve.
Note: The Mk1 sleeve fits all standard size rowing shafts (M4, M2).
Carbon fiber rowing handles are designed with comfort and ease of use as the top priority. All carbon rowing handles allow a 6cm range of adjustability. Correct selection of handle size is critical in optimizing performance. A handle that is too small may result in excessive wrist movement while feathering the oar. A handle that is too large may fatigue the rower's forarms. A variety of sizes, shapes and surfaces are available to accomodate the needs of all rowers.
Croker rowing handles are available with a variety of surfaces: blue foam rubber, timber veneer, and shrink rubber.
