Sapim Strong Spoke

Superior spokes with 2.3mm head- where spokes break!
Remainder of the spoke is 2mm.
Fatigue test / wheel revolutions : 1.600.000
Strength on middle section : 1400N/sqmm
Nipples : polyax 12 mm work well even with awkward spoke angles.
Heads need careful but firm bending round before tensioning but fit most modern hubs without drilling.
If they do need drilling, 2.5mm is perfect.
