• Computer designed to achieve ultimate strength at minimum weight
• JT combines leading-edge technology with top materials to produce the ultimate quality sprocket range with unbeatable value
• Every sprocket meets or exceeds the highest possible quality standards
• Sprockets are heat-treated and beadblasted to reduce material surface tension
• Front sprockets are made with top-quality Japanese C45 high carbon steel and SCM415 chromoly steel alloy
• Steel rear sprockets are made with top-quality Japanese C45 high carbon steel
• Aluminum rear sprockets are made with high strength Austrian 7075 T-6 anodized aluminum
