inc tax


TRAMPA's 6 spoke HYPA Hub is the lightest, strongest injection moulded 8 inch hub / wheel on the market today. Produced using original DuPont ingredients & the very latest in injection moulding machinery, no quality expense is spared!! HYPA Hubs are so strong, during testing our Crash Test Dummies (i mean the Team Riders) frequently inflated their HYPA wheels well beyond 75psi with no problems to report!

HYPA Hubs are available in loads of coordinating colours all of which are TRAMPA embossed proving our top quality, so to avoid disappointment dont go buying imitations! Our top quality continues as the HYPA Hubs construction uses A4 (Marine Grade) Stainless Steel Nuts & Bolts which are guaranteed never to rust.

HYPA Hubs are compatible with all known 8 Inch Tyres on the market today.

TRAMPA’s very own & genuine ABEC rated Bearings push perfectly into the HYPA Hub, guaranteeing the fastest spin rate possible. Use 12mm bearings (12x28x8mm) for 12mm axles or you can use Bearing Reducer Sleeves to fit your existing 12mm bearings onto 10mm axles (9.52mm or 7/16ths inch axles). 9.52x28x8mm bearings also fit TRAMPA hubs to 9.52mm Skate Axles.

Bearings are supplied at a discounted price when purchased with a set of hubs...
2 x Bearings cost only £2.50 x 4 = £10 per set of 8 making a £5 saving per set!

In this kit, you get everything you need to convert the GUMMIES ORRSOM Longboard to the URBAN ORRSOM Longboard...
