The crankbrothers modified wheel system now includes an aluminium range. The Crankbrothers synthesis wheels adopt a novel approach to wheel systems, focusing on a compliant front wheel paired with a stiff rear wheel to achieve optimal ride characteristics. The compliant front wheel enhances handling and control during turns, while the stiff rear wheel improves stability and tracking at high speeds. In the alloy range, these distinct characteristics are achieved through variations in spoke tension, spoke weight, spoke count, rim width, and rim weight.The range includes models for Enduro, XC/Trail, and E-bikes, aiming to cater to a wide range of riders. The Enduro and XCT models offer two hub options - a crankbrothers hub and an i9 1/1 hub, both with 4 degrees of engagement. Additionally, the availability of rim-only options for Enduro and XCT allows for custom wheel building.The specifications for the rear wheel are as follows:- Inner rim width: 31.5mm for 27.5/29 and 35.5mm for 27.5+- Spoke count: 32- Spokes: Sapim E-Strong- Weight: 1238g for 29, 1174g for 27.5, and 1181g for 27.5+- Hub engagement: 17 degrees
