The 240s hubs are some of the lightest hubs available, the front road hubs weigh in at just 105g. They are extremely reliable and should keep rolling for many years with a bit of care. Front hubs are available in 20-32h variants.
DT Swiss say:
"On tarmac or on a BMX track, 240s hubs are the benchmark for all high end hubs. Stainless bearings and the star ratchet freewheel system result in unmatched reliability."
The 240s front hub is suitable for radial lacing.
