PRIMO's 3 Spoke Composite Hubs
Are used when you wish to make 9 Inch Wheels. The PRIMO Hubs shape & size is totally different to that of the TRAMPA hubs design (a different spacer is needed to fix the to the TRAMPA Trucks) & so when comparing the Solid Primo Hub to the super-slim designs of the HYPA or SUPERSTAR hubs (which we use to fit 7 & 8 Inch tyres) the PRIMO Hub does weigh in at a little on the heavy side BUT It is currently the only option that TRAMPA offers should you wish to use 9 Inch Wheels. Its thick walled solid structure means the PRIMO Hub is made as close to near indestructible as that gets & it has a an awesome reputation for never failing on you....

TRAMPA ABEC 5 & ABEC 7 BEARINGS - 12 x 28 x 8mm & 9.525 x 28 x 8mm
TRAMPA’s very own & genuine ABEC rated Bearings have 2 Rubber Sealed sidewalls which protect them from the dirt they live in. They push perfectly into the any of the Hubs on the TRAMPA website as well as many other brands & they ensure the fastest spin rate possible. Use 12 x 28 x 8mm Bearings to fit the TRAMPA WHEELS to 12mm axles or you can use Bearing Reducer Sleeves to fit your existing 12mm Bearings onto 10mm or 9.525mm or 3/8ths of and inch axles. 9.525 x 28 x 8mm Bearings also fit TRAMPA hubs to 9.525mm Skate Axles.

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


PRIMO's 3 Spoke Composite Hub is only suitable for fitting 9 inch Tyres.  When compared to the super-slim design of the HYPA or SUPERSTAR hub, the PRIMO hub does weigh in a little on the heavy side, but the 3 spoke'd solid structure is a timeless classic with an awesome reputation for never failing on you & is currently the only option that TRAMPA offers should you wish to use 9 inch Wheels.

The 3 Spoke PRIMO hubs are assembled using just 3 heavy duty M6x30mm Stainless Steel Socket capped Bolts & Nylock nuts. Althought slightrly tighter to fit into than other hubs, TRAMPA's regular 28mm Bearings will fit perfectly into the Bearing housing of the PRIMO hub. As a top tip place the bearings in the frzzer for 30 minutes before inserting them into the hub, the cold will cause the metal of the bearing to shrink and easier to fit into the hub!

To fit the PRIMO 3 spoke hubs onto the TRAMPA TRUCKS you will need a special Axle Spacer to allow the hub to fit onto the axle & still have enough space to be able to tighten up the Axle Nut.

M6 x 30mm Socket Capped Allen-Key Bolt for primo hub - Marine Grade Stainless steel

TRAMPA's M6 x 30mm Socket Capped Bolt is made using A4 Marine Grade Stainless Steel. This Bolt is used to assemble the PRIMO 3 Spoke Hubs. The socket capped head of the Bolt screws neatly though the HUB eventually screwing into the Marine Grade Stainless Steel M6 Nylock Nut on the other side of the hub. 

Weighing just 8 grams each, these Bolts are lightweight, look very sexy & are totally non corrosive. Using Marine Grade Stainless Steel, means these Bolts will never rust on you! They can cope with the most harsh of weather conditions & they laugh in the face of sandy/salty beaches or muddy freeride tracks, which do turn other manufacturers nuts & bolts into corrosive rusting wrecks! As well as being Non Corrosive all of the TRAMPA Bolts are diped in BLUE THREAD LOCKING PASTE to ensure an extra strong secure fix between the Nut & the Bolt.

You’ll will need a 5mm Allen Key  to tighten & loosen the Bolt from the nut. Ensure all your Nuts & Bolts are tight before riding!

M6 Nut - Marine Grade Stainless steel Nylock Nut - Fixes Bindings & Trucks to Deck

Introducing TRAMPA's M6 (6mm Thread) A4 Grade Marine Grade Stainless steel Nylock Nut. This Nylock Nut will fit to all M6 Bolts regardless of their length. This A4 Marine Grade Stainless Steel Nut will never rust on you! It is fitted with the world renowned NYLOCK System (Nylock is a nylon locking system where Nylon is pasted into the threads of the nut so that when the bolt is tightened into the nut the nylon grabs the thread of the bolt holding it locking it in the thread ensuring things do not vibrate loose or fall off when being ridden on rough terrain like that which a Mountain or Kiteboard endures. The NYLOCK System is fitted as standard to all TRAMPA Nuts

This Nut is used to fix to the Regular shaped M6 Bolts that hold the TRUCKS to the DECK for the HOLYPRO Decks & also for the countersunk bolts connecting the L BRACKETS TO the DECKs. Use an 10mm spanner or SOCKET for a Ratchet Driver to tighten the Nut onto the Bolt. Always ensure your Nuts & Bolts are tight before you ride!

8 Inch Regular Inner Tube made by PRIMO - 200x50mm

PRIMO's own 8 Inch Inner Tube has dimensions of 200mm (outer diameter) x 50mm (width) & will fit into all known 8 inch Tyres & ATB hubs on the market!

The CST PRIMO Inner Tube incorporates slightly thicker rubber into its manufacture process which means the tube is slightly heavier than alternatives but does allow the rider to inflate slightly higherThis extra thickness also gives some extra resistance to punctures, but punctures suck, so always carry a spare inner tube when you are riding as you never know when you might get one.  

The PRIMO Tube uses a 90º Brass Inflation valve which will not rust on you & comes as you would expected with a plastic "anti dust" valve cap!

TRAMPA Tyre options for 3.75/4 x 2.5 Inch Rims includes 6 Inch URBANS, 7 Inch Tyres, All 8 inch Tyres, All 9 Inch tyres & all 10 Inch Tyres

Sets of 4 Tyres & Tubes available at a discounted price at this link


PRIMO 3-SPOKE Hubs have a 3.75 x 2.5 inch rim & will fit all 9 - 10 inch diameter tyres.  

Weighing 300g, Primo 3-Spokes are slightly bulkier than
TRAMPA’s other composite-hub designs. The cheaper choice for fitting 9” or 10” tyres to your board, Primo 3-Spokes use premium composites, paired with a thick-walled structure to make it one of the toughest hubs going!

PRIMO 3 spoke hubs are a 2-piece CENTRE-SET split-rim design, joined together using 3x M6x30mm Socket Cap bolts.


9” Wheels are a huge advantage when riding on challenging terrain. The Larger circumference allows for a higher rolling speed, while the extra width provides more extra grip.

9” PRIMO STRIKER TYRE - A favourite among boarder-X racers, the PRIMO STRIKER was designed for fast riding on hard-packed dirt. Made using a hard rubber compound with a Wide Center Bead to help achieve the maximum rolling speeds. The close cut grip pattern around the sides of the tyre gives loads of grip on changeable terrain.
 

9” INNOVA INLINE TYRE - With straight cut tread & the ability to handle high PSI, the INLINE  is the perfect option for easy rolling. Working best on smooth surfaces such as skate parks, tarmac or asphalt, the 3mm deep ‘In Line’ grooved surface, encourages the tyre to track in a straight line! Unlike standard Longboard/street style wheels, the pneumatic INLINE tyre is easily big enough to glide over cracks, stones or holes, & will handle hard-packed rougher terrain, such as gravel path with no problem.
 

9” DIAMOND TREAD TYRE - Made from relatively soft rubber with a close-cut tread pattern & a ballooned-shape, the DIAMOND TREAD Tyre is a perfect all rounder option, giving great grip on hard surfaces & good grip when heading off road - especially during the summer months.
 

9” MUD-PLUGGER TYRES - using a deep & aggressive tread pattern that creates 'Grip on top of Grip', with straight sidewalls and a rigid rubber structure, MUD PLUGGERS have a box-ier shape that increases surface contact. Able to run on both low & high PSIs, the wide center bead both reduces rolling resistance and improves traction! Produced using a soft 2PR rubber compound with a high TPI (thread-count per inch), the resulting tyre is amazingly grippy & hard-wearing!


Perhaps too big for boards, 10" wheels are perfect for go-karts, golf buggies, trikes, tractors & countless other applications.The larger circumference means less roll-resistance,  allowing greater top speeds. The extra width means the tyres allow more surface contact, meaning greater grip!

10" DURO-Tread Tyres are designed like the tyres you might find on a motor-enduro bike, these hard-wearing tyres are made for long journeys & potentially aggressive terrain.The simple-yet-effective tread on this tyre provides enough grip for on & off road use
 

10" Tractor Tread uses aggressive grip like that you’d find on (as the name suggests) a tractor. This tyre will have no problem finding grip, even in the slippiest of mud.



PRIMO's 3 Spoke Composite Hub is only used when the user wishes to fit 9 inch Tyres. Because of the extra size of this hub, when comparing to the super slim design of the HYPA or SUPERSTAR hubs, the PRIMO 3 Spoke hub does weigh in a little on the heavy side, but the 3 spoke'd solid structure is a timeless classic with an awesome reputation for never failing on you & is currently the only option hub that TRAMPA offers should you wish to use 9 inch Wheels.

The 3 Spoke PRIMO hubs are assembled using just 3 heavy duty M6 x 30mm Stainless Steel Socket capped Bolts & M6 Nylock nuts. Althought slightrly tighter to fit into than other hubs, TRAMPA's regular 28mm Bearings will fit perfectly into the Bearing housing of the PRIMO hub. As a top tip place the bearings in the frzzer for 30 minutes before inserting them into the hub, the cold will cause the metal of the bearing to shrink and easier to fit into the hub!

To fit the PRIMO 3 spoke hubs onto the TRAMPA TRUCKS you will need a special Axle Spacer to allow the hub to fit onto the axle & still have enough space to be able to tighten up the Axle Nut.
