The Crankbrothers Synthesis Alloy E-MTB 27.5+ Boost Front is part of the crankbrothers tuned wheel system. This range of aluminium wheels takes a unique approach to wheel systems. The focus is on having a compliant front wheel and a stiff rear wheel to achieve the best ride characteristics for each rider.By having a compliant front wheel, the handling and control in turns are improved. On the other hand, the stiff rear wheel enhances stability and tracking at higher speeds. These differing characteristics are achieved through variations in spoke tension, spoke weight, spoke count, rim width, and rim weight.The alloy range of the Crankbrothers Synthesis wheels includes models for Enduro, XC/Trail, and E-bikes. The aim is to accommodate as many riders as possible. For the Enduro and XCT models, there are two hub options available - a crankbrothers hub and an i9 1/1 hub, which provides 4 degrees of engagement.Additionally, the Enduro and XCT models are also available as rim-only, giving riders the option for custom wheel building.Here are some specifications for the Synthesis Alloy E-MTB 27.5+ Boost Front wheel:- Inner rim width: 31.5mm for 27.5/29 and 35.5mm for 27.5+- Spoke count: 28- Spokes: Sapim E-Light- Weight: 980g for 29, 915g for 27.5, and 928g for 27.5+(Note: If the title looks like a part number or contains a color, such as Black or Grey, please ensure that the text does not mention it.)
