The Crankbrothers Synthesis Alloy XCT Rim is part of the aluminium range in the crankbrothers tuned wheel system. This range of wheels takes a unique approach, focusing on a compliant front wheel and a stiff rear wheel to achieve the best ride characteristics for each rider. The compliant front wheel improves handling and control in turns, while the stiff rear wheel enhances stability and tracking at high speeds. To achieve these different characteristics, the alloy range varies in spoke tension, spoke weight, spoke count, rim width, and rim weight. The range includes models for Enduro, XC/Trail, and E-bikes, catering to a wide range of riders. For the Enduro and XCT models, there are two hub options available - a crankbrothers hub and an i9 1/1 hub, offering four degrees of engagement. If you prefer, you can also choose the Enduro and XCT rim only options, allowing for custom wheel building. Front Rim: - Inner rim width: 26.5mm - Spoke count: 28 Rear Rim: - Inner rim width: 24.5mm - Spoke count: 32 Experience the improved performance and ride quality with the Crankbrothers Synthesis Alloy XCT Rim.
