TRAMPA's Generation III SPUR GEAR DRIVE Motor Mount is the ultimate drive system for off road riding! Made predominantly from T6 Aluminium, every piece has been precision made to give simple assembly & maximum performance.

The performance from the SPUR GEAR DRIVE Motor Mount is likened to a Motorcross bike - designed with insane torque for astonishing acceleration, top speeds & jumps. Opposed to the PRO BELT DRIVE Mountainboard, which is designed like a Motor-Enduro bike - for longer, more comfortable rides, and a bit more top-end speed.

The SPUR GEAR DRIVE Motor Mount will only fit to Precision CNC Hangers, using TRAMPA's special Conical Clamping system to securely attach onto the Hanger. The Assembly of any of the Pro Motor Mounts is incredibly sturdy & robust; perfect for the rough terrain they’ll be ripping across.

The SPUR GEAR DRIVE uses Helical or Straight cut gears. Helical Gears give a gear ratio of 1:5.8, whereas straight cut gives 1:5.9 – meaning straight-cut gears have more power when accelerating - however, Straight-cut gears are louder than the Helical when riding (although we’ve found some mad people who like the noise!).

You can further fine-tune the performance by changing the Rear Drive wheel size. Changing from 8” to 9” or 10“ Tyres has a massive effect on the performance of the board. Check out the Spur Gear gearing chart to see estimated top speeds of different tyre & pulley combinations.

It is only possible to fit the TRAMPA 5 Spoke Hubs to Pro Drive Slave Pulleys. This means the 5-Spoke Superstar & Megastar wheels fit no problem. However it is only possible to run 8, 9 or 10 inch tyres on the Pro Drives, due to low clearance around the housing tubs.

Spur Gear Slave Pulleys are made using premium POM plastic, giving them the best strength : weight ratio possible.

TRAMPA's EXTERNAL SPUR GEAR DRIVE is housed within a super strong, rubber-sealed Tub, CNC’d from a solid block of heat-treated T6 Aluminium. Ensuring all the moving parts are safe from the elements, as well as knocks and bumps that come along naturally when riding.

We recommend you service your board every three rides, or after any particularly tough ride. Check the hardware is tight, the gears are greased, & for any damage - particularly to the motor mounts/trucks. Ensure the tub is free from any dust/dirt. Servicing your board is important for keeping it running smoothly, as well as for your safety when riding.

CUSTOM Spring Truck Baseplate - Extruded T6 Aluminum Anodised & CNC precision Milled

The  INFINITY Baseplate will fit to all of the TRAMPA Spring Truck Hangers but is designed specifically to work in conjunction with the Mini Spring Hanger as it houses a NEW Dual Spring Adjuster position! When the Springs are moved to the new inside position, the new location allows the rider to turn the board very very easily, making it perfect for fast carve riding on all kinds of terrain. You can see the new & growing TRAMPA STREET CARVER range of products here...

The  INFINITY Baseplate is, as its name suggests, designed & built to last forever! Aircraft grade 6061 Aluminum is forced through a Die to create our re-enforced extruded profile. Extruding Aluminum ensures consistent high quality strength. Once Extruded the Baseplate is T6 Heat Treated. Heat treating extruded aluminum fuses the molecules even closer together making it as strong as possible, enabling the INFINITY Baseplate to easily cope with the extreme stresses of all types of off road boarding.

Once Heat Treated, the profile has its fixing holes punched into position & then its Bead Polished in preparation to be Anodised Silver. Once the colour has dried, the Baseplate is then returned to the factory for the precision CNC Machine to accurately mill the Kingpin holes, giving the exact precision required for constructing the Truck.

Custom TRAMPA DAMPA


 

The TRAMPA DAMPA is a Urethane Elastomer that fits inside the Spring of a Truck. Its purpose is to support the Spring & give extra resistance during steering. Its clever design has three balls stacked & connected on-top of each other. The middle ball is slightly fatter than the outer two, during steering they all compress against each other giving greater feed back in your turns. This stacked design gives a fantastic progressive feel to steering.

By varying the SHORE DUROMETER (Rubber Hardness) strength of the Urethane mixture, we can control the amout of movement in the DAMPA. This in turn allows the rider to custom tune the resistance of their steering perfect to their requirements. The spheres of the DAMPA fit perfectly into the cup of the specially made TRAMPA SPRING RETAINER which is the part that locates & locks the Spring in the the TRAMPA SPRING TRUCKSand they instantly start to work with the slightest movement from the rider. TRAMPA DAMPA's work in harmony with the rider, supplying the perfect amount of steering resistance whilst eliminating all chances of speed wobble. Now available in 5 different steering resistance's for all levels of rider out there, Orange DAMPA's are for easy steering, whilst White DAMPA's are for the totally committed! 

Turning the Spring Adjuster clockwise pre-loads the tension in the Spring and Dampa. This can be adjusted on the fly to suit the terrain & conditions. Turning the spring adjuster too much will put pressure on the Dampa & eventually it may split. Rather than putting too much pressure into the Dampa, consider up-grading the Dampa to a harderShore Durometer as this will most likely increase your perfomace than overtightening a Dampa thats not stiff enough for you.

SPUR Gear Drive T6 Tub with TRAMPA Logo

CNC’d from a solid block of T6 heat-treated Aluminium, the SPUR GEAR DRIVE HOUSING is as strong as it is sleek. When paired with the CNC’d TUB COVER, the completed housing keeps the elements outs, the gears & belts clean & dry, & the whole board riding smoothly.
Designed to tightly slip around the CNC’d Hangers on Precision Vertigo Trucks, the Tub locks the entire drivetrain is accurately & securely in line.
With a bash-guard integrated into its design, you can be confident the tub will survive all the knocks-&-bumps its bound to receive on a ride.
Fits 10-tooth Straight or Helical Motor Pulleys & 58-tooth Helical or 59-tooth Straight-cut slave pulleys.
The Housing is perfectly symmetrical, allowing it to slide onto left or right drive trains.

 

TRAMPA SPUR Gear Drive T6 Aluminium Tub Cover - SILVER

The Spur Gear Tub Cover is crucial to keeping your drive system free of dirt & debris. CNC’d from Premium Aluminium, giving it the perfect weight: strength ratio, the cover slots tightly over the Spur Gear tub, sealing off the drive system & leaving room for the Hub Adaptor & Rubber Seal

SPUR Gear Drive Bash Guard - RIGHT Side - SILVER

Made using hardened steel, the spur gear bash guards are designed around taking the brunt of any hits away from the drive train.

Fits to the right drivetrain.

SPUR Gear Drive Bash Guard - LEFT Side - SILVER

Made using hardened steel, the spur gear bash guards are designed around taking the brunt of any hits away from the drive train.

Fits to the left drivetrain.

SPUR Gear Drive Motor Adaptor SILVER

Housing a precision bearing for Motor Axle Support the SPUR GEAR DRIVE Motor Adaptor is used for attaching the motor securely to the drivetrain.
Precision CNC’d from hardened steel, the Motor Adaptor also allows for the use of PRO MOTOR HOUSING.

SPUR Gear Drive Hub Adaptor

The Hub Adaptor attaches the Slave Pulley to the Hubs, delivering the power of the motors to the wheels. Connects to SUPERSTAR or MEGASTAR hubs.

Precision CNC’d from Hardened Steel.

Connects to Slave Pulley using 5x m5x12mm Torx head screws.

Spur Gear Drive 10 Tooth HELICAL or STRAIGHT-Cut Motor Pulley

SPUR GEAR DRIVE Motor Mounts can run using Helical or Straight-cut pulleys.

Helical Motor Pulleys give a gear ratio of 1:5.8 when paired with the 58 tooth Helical Slave Pulley. The Helical shape allows for more surface contact between the Slave & Motor Pulley Teeth, creating a quiet & efficient drive. 

Straight-cut Motor pulleys pair with a 59 tooth Slave Pulley, giving a ratio of 1:5.9 – meaning there will be a tad more power when accelerating in comparison to the Helicals. However, due to less surface-contact between the gears, Straight-cuts are much louder when riding along (although we’ve found some mad people who like/prefer the noise!).

Made using Hardened Steel.

Spur Gear Drive 58 Tooth HELICAL or 59 Tooth STRAIGHT Cut Slave Pulley

Spur Gear Drives are compatible with Straight-cut or Helical Gears.
Made from premium POM plastic
, the 58-tooth Helical Slave Pulley pairs with the 10-tooth Helical Motor Pulley, giving a gear ratio of 1:5.8. Compared to the 59-tooth Straight-cut Slave Pulley’s ratio of 1:5.9, Helical gears will ultimately have a higher top speed.  

Helical Gears provide more surface contact between the teeth, resulting in a smoother & quieter ride.

Straight-cut Gears are the cheaper option – still providing amazing torque & performance, while running a bit louder than helical.   

Connects to Hub Adaptor using 5x m5 x 12mm Torx head screws.

CNC Precision VERTIGO E-MTB Hanger - 12mm HOLLOW Steel Axles - Used in conjunction with all PRO Series Mountainboard Motor Mounts - 16 inch wide

The TRAMPA VERTIGO ELECTRO HANGER was designed with motor mounting in mind. Using a precise CNC milling machine, we’ve squared off the edges of the hanger, meaning TRAMPA Motor Mounts slide directly (and snugly) onto the hanger. This ensures the maximum amount of support for the motor mounts, and no room for the motors to wobble while riding.

TRAMPA's VERTIGO HANGERs are a slimmed down, lightweight version of the original solid style INFINTY Hanger. To supply the maximum strength at all times all of our hanger bodies are produced from premium FORGED ALUMINUM produced as 1 solid piece. The precision CNC milling machine is applied to the infinity hanger & accurately cuts out the bulk of the material without stripping any of its critical strength, resulting in the VERTIGO hanger being almost as strong as the Infinity BUT nearly 20% lighter in weight. :-)

The Vertigo Hanger is fitted with 12mm HOLLOW STEEL Axles. The Hollow axles are HEAT TREATED - making them substantially stronger & resistant to impacts. Hollow Axles are nearly half the weight of Solid Axles!

CNC milling guarantees precision work - ensuring the Kingpin Holes are accurately placed. This results in the best performance for the rider, as well as making the truck easy to assemble & service. In order to gain the "Two Tone Pimp Finish" the VERTIGO Hanger is ANODISED GLOSS BLACK for metal protection & colour coordinated good looks, before the CNC work is carried out.

The VERTIGO Hanger measures 16 Inches in total width. When the wheels are fitted to the Hanger, the wheels have a center wheel width of 14 Inches apart.

7/16ths Nut - Marine Grade Stainless steel Nylock Axle HALF nut (W7/16-20T UNF) - Fits to 12mm Axles

This very special 7/16ths of an inch Marine Grade Stainless steel Nyloc HALF NUT is custom made specially to fit the TRAMPA products. Half nut means - half as the size of a regular nut, so half the size = half the weight of a normal nut.. By using Half nuts on the axles reduces the over all length of the axle & kingpin therefore further reducing weight in the Truck! A few Grams here & a few grams there soon adds up & makes all the difference to the total Truck & consequently deck weight, specially in critical areas of the deck such as the wheels area, where a few grams makes all the difference...

This very special 3/8ths of an inch Marine Grade Stainless steel Nylock Half Nut official factory measurements are  W7/16 - 20T - UNF. This Nut is used to hold the wheels onto the axles of the Spring Trucks fitted with 12mm axles. The Nut is fitted as standard with the world renowned NYLOC System. The Nyloc "locks the Nut onto the Bolt" eliminating vibration, keeping your nuts tighter for longer!

Use a 16mm or 5/8thths of an Inch spanner to tighten / loosen the Nut onto the Axle or Kingpin. Do not overtighten the nut & make sure the wheel can spin freely but does not rattle & do not crush your bearings. Being Marine Grade Stainless Steel this nut will not rust you! Always ensure all ur nuts are tight before you ride!

Wheel support spacer for all TRAMPA Wheels on 12mm ATB Axles - CNC precision 12mm x 16mm x 18.2mm - REGULAR

This special Spacer measures 12mm (id) x 16mm (od) x 18.2mm (long) & has 2 uses!. It is firstly known as the Bearing Support Spacer as this Spacer fits between the Bearings of a 6 Spoked HYPA Hub, (when mounting the HYPA wheel onto 12mm Axles) & secondly it is also known as the AXLE SUPPORT SPACER as this spacer is also used to position any of the TRAMPA wheels in the perfect position onto the axles of 12mm TRAMPA Spring trucks....

TRAMPA spacers are produced as one long tube. The Tube is Heat Treated to gain extra strength & is then Bead Polished to give the metal extra surface protection & a shiny best appearance. The tube is then cut to the exact length for precision mounting. 

Custom Colour Spring - Powdercoated Sprung Steel Steering Springs

TRAMPA's SPRINGS are coiled to precision & fit into the TRAMPA Spring Trucks perfectly. They easily squeeze into the space between the Baseplate & Hanger & being made to measure they are firstly very easy to fit with no clamps or tools required to squueze them into position & secondly to be super responsive to the rider.!  Once the spring assembly is fitted correctly the steering resistance is taken up instantly!

Our Springs have been designed to work in perfect harmony with the TRAMPA DAMPA's & TRAMPA SPRING RETAINER providing maximum performance from the "Spring assembly" to the rider. The DAMPA's drop into the SPRING & the SPRING RETAINERS seal the ends of the spring, holding the DAMPA in exact position to be pre-loaded & squeezed into the truck. Using just a little bit of muscle, squeeze the loaded spring into the truck, then lock the spring into position using the Spring Adjuster & M5 x 12mm Countersunk Bolt. The TRAMPA spring Truck steering system is highly responsive & totally customisable by interchanging the DAMPA's to harder Urethane. Other Mountain Board brands springs will not fit the TRAMPA Trucks as they are a different in dimension.

TRAMPA Springs are available in a selection of Powder-coated colours for good looks & of course for best surface coating protection & this one comes to you in Powder Coated Black. 

Spring Retainer - Specially designed to work in harmony with the Dampa & spring

TRAMPA's very own & very special re-enforced Spring retainer. Specifically shaped to fit tightly inside the TRAMPA springs & snugly hold the Trampa Dampa in the exact position to give precision steering to the rider. Made by Injection Moulding using original Dupont Materials, with an extra wide Marine-Grade Stainless Steel Flanged Insert seated internally, re-enforcing the Retainer. The Extra Strength of the re-enforced flange, eliminates the need for a very fiddly fitting washer, that is still found in the MBS and Scrub boards today.

Designed to work in harmony with the TRAMPA spring and TRAMPA Dampa to help create immediate resistance from your steering system. With TRAMPA Embossed around the rim of the retainer - you'll have performance with pimpness!

Spring Adjuster - Marine Grade Stainless Steel

TRAMPA's very own & very special SPRING ADJUSTER is made using A4 MARINE GRADE STAINLESS STEEL & is guaranteed never to rust on you! The Spring adjuster is fitted to the trucks once the springs have been pushed into position. The spring adjuster pre-tensions the steering suitable for the rider’s requirements. We designed the Spring Adjuster to be slightly shorter in length than other brands’, to avoid  the tip of the adjuster poking through the internal of the Spring Retainer, and interfering with the performance of the DAMPA located on the inside of the Retainer.

Should you need extra resistance from your steering because you wish to ride fast, or if you need more steering because the course is twisty, then you can very easily & quickly adjust the resistance of your steering by simply turning the spring adjuster in the correct direction. To get the most out of your trucks on changeable terrain, simply use a 4mm Allen Key to make your adjustments. Winding the Spring Adjuster clockwise increases the steering resistance, which in turn restricts wobble at high speed. Turning the Adjuster anti-clockwise loosens the steering allowing a more carvey ride.  

DO NOT over tighten your Spring Adjuster, as this may crush your DAMPA. If you need more steering resistance upgrade your DAMPA's & do not over tighten!
