The Crankbrothers Synthesis Alloy Enduro 29 Boost i9 Rear Shimano Micro Spline is a part of the crankbrothers tuned wheel system, which now includes an aluminium range. These wheels offer a new approach to wheel systems, with a focus on a compliant front wheel and a stiff rear wheel to optimize ride characteristics.The compliant front wheel improves handling and control in turns, while the stiff rear wheel enhances stability and tracking at high speeds. The alloy range achieves these differing characteristics through variations in spoke tension, spoke weight, spoke count, rim width, and rim weight.The range includes models for Enduro, XC/Trail, and E-bike riders, catering to as many cyclists as possible. For the Enduro and XCT models, there are two hub options available - a crankbrothers hub and an i9 1/1 hub, both offering 4 degrees of engagement. Furthermore, the availability of rim-only options for Enduro and XCT allows for custom wheel building.The rear wheel of this specific product features an inner rim width of 29.5 and a spoke count of 32. It is equipped with Sapim Race spokes and weighs 1018g for 27.5 wheels or 1048g for 29 wheels. The hub engagement is 4 degrees.Make the most of the Crankbrothers Synthesis Alloy Enduro 29 Boost i9 Rear Shimano Micro Spline and experience its exceptional performance on your rides.
