How to put a wheel on an Infinity or Vertigo truck

How to put a wheel on an Ultimate Truck

The 6 Spoke HYPA Wheel is the lightest & strongest plastic injected Hub / Wheel on the market today! Its produced using original DuPont ingredients & the best Injection Moulding machinery, no quality expense is spared during the production of this amazingly strong little hub!

During testing the HYPA Wheels performance surpassed all expectations. :-) This little 8 inch wheel proved to be so strong, when the "Crash Test Dummies" (i mean the Mountainboard Team Riders) inflated their tyres well beyond factory recommendations! (Tut-Tut Naughty-Naughty!) The extra inflation resulted in substantially faster roll speeds, giving them the extra time in the air to complete their huge freestyle moves & still have time land in 1 piece! I'm pleased to tell you there were no explosions from the over inflation to report whilst breaking a HYPA HUB is just about unheard of, something extraordinary has to go wrong before these hubs do! If you have seen some of the crazy stuff the MTB & KTB teams have put the equipment through over the years, with genuinely almost no problems to report, you will have no doubt of the HYPA WHEELS performance capabilities.

HYPA Hubs are available in loads of coordinating colour combinations its difficult to make the decision as to which option you like the most! You can choose from naked Matt Black or White to Painted Gloss Red or Gloss Blue with Painted Black or White TRAMPA Logo's or Printed in Winter or Army Camo, the choice is all yours... :-)

TRAMPA's HYPA hubs are held together using Marine Grade (A4) Stainless steel Nuts & Bolts & will never rust on you. Our bolts are perfect for bad conditions. Not only will the nuts & Bolts never rust on you all the Bolts used by TRAMPA have been dipped in a special Blue Locking Paste, whilst all the Nuts that TRAMPA uses are fitted with the world renowned Nyloc nylon nut locking system, all of these no expense spared small details ensure you get the absolute best product possible! To help prevent you from purchasing imitations, TRAMPA's HYPA Hubs are always TRAMPA embossed between the spokes proving our top quality! 

Your tyre requirements will be defined by the surface you are riding on, however you will be pleased to read that all of the HYPA Hubs will fit into any of the 7 inch Tyres or 8 Inch Tyres on the TRAMPA website. TRAMPA Hubs are also compatible with all known 8 Inch Tyres that are currently on the market, including any other Mountainboard or Dirt Scooter brand.

TRAMPA’s very own & genuine ABEC 5 rated Bearings, push perfectly into the 'Centre Set' bearing housings either side of the hub. The bearings are supported internally by use of a 'Bearing Support Spacer' sitting on the axle in the middle of the hub, guaranteeing the position of the bearings & the smoothest spin rate possible. TRAMPA's Bearings will fit onto 9.525mm, 10mm & 12mm Axles. The metric measurement of 9.525mm, is equal to the US Imperial measurement 3/8ths of 1 inch. Bearing Reducer Sleeves downsize your 12mm Bearings to fit onto 10mm Metric Scooter Axles or 9.525mm (3/8ths of an inch) Imperial Skate Axles. Bearings can be supplied at 50% of the usual retail price when purchased with a wheel... 2x Bearings cost just £2.50 per pair (usually £2.50 each), resulting in a £10 saving per set of 8x bearings, 8 bearings are enough for a set of 4 wheels!

TRAMPA's 200mm x 50mm - 8 Inch wonder wheels are the primary choice sized wheel for many inventors developing sporting equipment requiring very strong whilst very light weight, small pneumatic wheels for their applications to work correctly. Mountainboards, Kiteboards, 2Wheel, Dirt-Scooters, Bikes Skates, Sledges, Trikes, Skikes, Model Planes, Single Seater Planes, Dog Sledding, Dirt Skiing, Transportation Chariots & now lots of exciting electronic applications all due to come to the market very soon, all require an 8 inch wheel for their best movement... If you have a wheeled project on the go & you would like to fit TRAMPA's 8 inch wheels onto it, then in your design you need to use a 12mm axle & you will need to give an axle mounting space of 34.2mm in order to fit the TRAMPA Hubs correctly.

M4 x 35mm Socket Capped Allen-Key Bolt - Marine Grade Stainless steel with locking paste

TRAMPA's M4 x 35mm Socket Capped Bolt is made using A4 Marine Grade Stainless Steel. This Bolt is used to assemble the TRAMPA HYPA HUBS. The socket capped head of the Bolt fits neatly into the Bolt housing of the HYPA HUB marrying into the M4 nut located in the housing on the other side of the hub.

Weighing just 3 grams each these bolts are very lightweight. They 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 will need a 3mm Allen Key to tighten & loosen the Nuts & Bolts from the hub. Ensure all your Nuts & Bolts are tight before riding!

M4 Nyloc Nut - Marine Grade stainless steel Nylock Nut - Hub Nuts

Introducing TRAMPA's M4 (4mm Shaft) A4 Marine Grade Stainless steel Nylock Nut. This Nylock Nut will fit to all M4 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 thread locking security System is fitted as standard to all TRAMPA Nuts. 

This Nut is used to fix to tighten to the M4 Socket Capped Bolts that hold the HYPA & SUPERSTAR hubs together. To fit the nuts M4 use an 8mm spanner or  8mm Ratchet Socket to turn the Nut onto the Bolt whilst holding the bolt with a 3mm Allen Key. Always ensure your Nuts & Bolts are tight before you ride!

This extra performance means the TRAMPA HYPA hub can handle much higher than recommended tyre inflation pressures, generating substantially higher than normal roll speeds. Back in the day during testing, our crash test dummies (i mean the Team riders) commonly rode with these hubs well above 80psi & beyond.... 

The HYPA hubs are held together using only the best Marine Grade (A4) Stainless steel Nuts & Bolts so they definitely wont rust on you (EVER) & are therefore perfect for bad conditions.

SLICK CUT 8 inch Tyre measure 3.75x 2x 8 Inch or 200x50mm with 3.75 inch Rim fits all 3.75 inch Hubs KEVLAR Banded - BLACK

Weighing in at just 280g INNOVA's 8 Inch SLICK-CUT STREET TYRE is the lightest, fastest 8 Inch tyre on the market today!

Its not just any old Tyre! Contained within its slick cut surface hides a few tricks that have drastically reduced the over all weight, whilst improving performing performance by allowing higher inflation pressures than ever before!!

Usually a tyres construction consists of 2 steel bands (The steel bands help to keep the tyres shape & allow tyre to slip onto the hub) being held together with 'piano string'esk' kind of thread (thick & Heavy). This inner construction is placed into a rubber mould, hot rubber is applied & forming machines make the final profile for the requirement. BUT instead of using the heavy Steel Bands the TRAMPA SLICK CUT TYRE uses Ultra lightweight KEVLAR Bands. KEVLAR is one of the strongest materials known to man & is commonly found in premium bicycle tyres which are known to inflate to well over 100psi. The KEVLAR Bands are held together using the highest quality Thread there is! High quality thread is incredibly thin therefore ultra light weight whilst not forgetting amazingly strong at the same time! As the Thread is thinner but stronger we are able to use more thread, making it even more stronger! This method is known as a high TPI (Threads per Inch), the TRAMPA SLICK CUT IS Very HIGH TPI!! 

To save even more weight TRAMPA's SLICK CUT Street Tyre is coated in top quality premium rubber using quite a hard compound that was originally designed for bicycles when road racing. As the Slick Cut tyres construction is so strong & because we have used a premium rubber supplier for our coating (INNOVA), we have been able to reduce the amount of rubber used for the cosntruction of the SLICK CUT Tyre to just 2 Layers of rubber (2PR) BUT with all of the upgrades & improvements we have put into its construction the Slick Cut tyre has been 4PR rated! 

This double reenforcement, triple weight saving combination allows the rider to inflate to much higher than normal inflation pressure's, thus naturally increasing top end roll speeds allowing the rider to go faster than ever before!  All this whilst reducing the over all weight of the tyre by 1 third of its original! 1 third of the weight becomes incredibly substantial when 4 of these tyres are attached to any one board. Higher roll speeds & lighter weight boards is the best of both worlds with this product!

The SLICK CUT TYRE has a perfectly smooth rounded profile with a very wide center bead making it our stock tyre for the out coming TRAMPA DIRT SCOOTER. Its profile is designed to help the rider max out top end roll speeds & maintain movement! A smooth profile & high inflation capability means this tyre is the perfect option for high speed street rolling freaks as the grip pattern is working best on hard packed surfaces such as Skate parks, Tarmac or Asphalt!
