Polyoxymethylene (P.O.M) is an engineering thermoplastic used in precision parts that require high stiffness, low friction and excellent dimensional stability. It's the perfect material for drifting with it's extremely low co-efficient of friction and high abrasion resistance giving a similar feel to PVC on go kart tyres. Characterised by its high strength, hardness and rigidity it is ideal for riding higher grip surfaces or for advanced riders. The P.O.M gives the ultimate drift experience. For the 49'er hub only.
