I purchased the Reynolds 11 Speed Freehub body (https://www.jensonusa.com/...1-Speed-Freehub-Body) after reading that it an upgrade path for Sram S60 / S80 rear wheels. However after purchase and installation, this increased the axle width to 134mm and will require a redish of 5mm to the drive train side. The kit includes 2 end caps and I only used the drive side end cap (I tried using the original end cap on drive side but the chain doesn't have enough clearance against the chainstay). If there a seperate non-drive side end cap that is required? I scowled the web and I did not find any information on the install process other than it worked. Is there anything I am missing? I understand the wheel is 10 years old but would love to still get use out of them.
