Marine grade stainless steel nuts with super strong Nylock locking system. Spacers should be replaced from time to time to ensure smooth running. Half nuts are used to shorten axle lengths and reduce weight.
Use a 16mm spanner to tighten your nuts onto the axles. Do not over tighten the nut as this will crush your bearings. Equally, do not leave the nuts loose as this may damage your hub or bearing. Ensure your nuts are "nipped perfectly" before riding for maximum performance. Always ensure your Nuts & Bolts are tight before you ride!
