375mm x 15mm High Torque Drive (HTD) 5M (5mm Tooth Spacing) High Power (HP) MIGHTY BELT for GUMMY Wheels with 44 Tooth Pulleys on ORRSOM longboards

This is a 375mm long x 15mm wide High Torque Drive (HTD) Re-enforced Rubber Belt, which has 5mm Tooth Spacing (5M).

All of the Transmission Belts TRAMPA uses are a High Power (HP) rated. They are made by the world famous German company called STRONGBELT & thier belts are normally used for heavy industry applications.

We use this Strongbelt is used to transfer the power from the motor, through the Motor Pulley generating movement in the slave wheel of the TRAMPA ORRSOM Electric Longboards.

TRAMPA opted to set a new standard in E-Skating, becoming the first in the world to fit to all of the E-Boards in its range, a 15mm wide TRANSMISSON BELT as standard! Our standard 15mm belt is almost double the width of nearly all other E-Sk8's out there, they tend to use a flimsy off the shelf 8/9mm transmission belts which can be prone to stretch, slip & ultimately snap. 

Using a re-enforced 15mm wide High Power Belt reduces stretch, eliminates slip & as a consequence provides a constantly smooth whilst incredibly intuitive power delivery direct to the rear Drive Wheels of your board. When accelerating or engine breaking (KERS), even from a standing start the STRONGBELT power is smooth & does not slip, or strain the motor, it does a damn gooood job!.....

STRONGBELT, as their name suggests, is a heavy industry brand that usually supplies the likes of Train manufacturers, where serious levels of quality with no excuses on failure are expected from the product as standard, as failure for such an item is serious as the consequences may result in death! STRONGBELT weave KEVLAR into their Pulley Belts, Kevlar is one of the strongest fibers known to man, its often added into materials to gain extra strength.... STRONGBELT have the best reputation in the Power Transmission Industry. These extra quality details in the production of our electronic motor drives, provides the maximum responsiveness achievable whilst maintaining a super smooth power delivery to the rider at all times. 

44 Tooth Slave Pulley - HYPA or SUPERSTAR/MEGASTAR - URBAN Motor Mounts

TRAMPA's 44 Tooth Slave Pulley has been designed to be used specifically when connecting electric motors through the URBAN Motor Mounts when using the new & oversized, super grippy GUMMIES longboard style tyres.  Frank was un-able to design 1 pulley to fit all styles of TRAMPA hub, so there are two different models for HYPA or SUPERSTAR/MEGASTAR Hubs.

The 44 Tooth Slave Pulley has been precision milled from super-light-weight & mega strong Heat Treated T6 Aluminum. The pulleys teeth stand 5mm tall, this is the same size teeth as that found on TRAMPA's Premium 15mm wide German made 'Strongbelt' & when the Strongbelts are wrapped around the pulleys, the belt fits so efficiently it has what we call HIGH TORQUE DRIVE (HTD). HTD insures all of the motors Torque is pushed through the pulleys into the wheels & when coupled with the amazing VESC 6 & 12s Battery power provides instant smooth unreal Power on tap to the rider!

This smaller sized 44 Tooth pulley is actually higher in gearing than the 66 tooth & therefore when fitted it increases the final drive (top Speed) compensating for the smaller sized final drive the wheel was originally intended to fit to... Gummies tyres only measure 125mm which are obviously smaller than 6.5, 7 & 8 inch wheel options we also offer so the Gummies Tyres love the extra gearing the 44 Tooth Brings :-)

TRAMPA's 44 Tooth Slave Pulley for HYPA hubs works in conjunction with all & any of the 13, 14 or 15 tooth Motor Pulley in the range. Changing your Motor Pulley will drastically alter the performance & characteristics of your ride... 13 Tooth motor Pulley is best for Hill Climbing whilst 15 Tooth Motor Pulley is best for high speed, 14 tooth motor Pulley will give you good all round performance...

To connect the 44 Tooth Pulley to the hubs you will need 5 or 6x M4x40mm Socket capped Bolts which screw through the wheel assembly directly into the Pulley very neatly!

Custom 15mm wide Motor Pulley 13, 14 or 15 tooth

TRAMPA's 15mm wide 13-15 Tooth Motor Pulleys connect directly to the Motor Axle & are secured into position using a Magnetic Fixing Key & 4mm Locking Grub Screw.

These custom made Motor Pulley Wheels  fit 15mm wide STRONGBELTS, which should never stretch or break whilst at the same time providing a very smooth power delivery to the user - even from a standing start.

Choice of Aluminium or Black Steel. Aluminium Pulleys are perfect for those looking to save every gram possible on their board - Black Steel Pullys are heavier, but much harder wearing.

Changing your Motor Pulley &/or Drive pulley wheels will drastically change the performance of your ride... :-)

13 Tooth
Best performance for climbing steep inclines.

14 Tooth 
Best all-round performance

15 Tooth 
Best performance forreaching top speeds.

The KEYWAY connects between the Motor Pulley & the Motor Axle Shaft to eliminate slip under power 3x3x8mm

TRAMPA's Motor Axle Shaft to Pulley KEYWAY measures 3 x 3 x 8mm. It connects into the Motor Pulley when mounted onto the motor Axle Shaft & is used to center the pulley on the Axle & to assist in delivering all the power from the motor without slip! This KEYWAY will fit to all TRAMPA motors amongst others.

TRAMPA's Axle length measures 38.5mm (from motor housing to end of shaft) & has a Diameter of 8mm. The centre of the key (3 x 3 x 8mm) sits 16.70mm away from the Motor front. Front side of Motor to Center of Key! Deduct 4mm & you have the length from front side of motor to the start of key....

PRECISION Shim spacer - STAINLESS STEEL - Bridges tiny gaps on axles - 9.525 x 13.525 x 1mm

This tiny STEEL Shim Spacer is precision made to give maximum performance! It is used to hold the bearings in the perfect position & also to bridge tiny gaps on the axles, ensuring an accurate fit with NO rattles!

The Shim spacer slips onto the axle fitting either side of the Bearings when the wheel is being fitted onto 9.525mm Axles.

This tiny spacer positions the wheel perfectly on the axle, holding the Bearing in the best possible place to help achieve maximum spin rate for the wheel. Its little parts like these that suffer the most amount of abuse, especially when they are used in the harsh conditions that they are. Check from time to time they are in good order & possibly replacing them every now & then this good proactice will ensure your board stays in tip-top condition, always!

Internal Bearing support spacer used with 8mm O-Ring on 9.525mm axles - 9.525 x 13.525 x 16.5mm

This special Spacer measures 12mm (id) x 16mm (od) x 16.5mm (long) & is known as a Bearing Support Spacer. This Bearing Support Spacer fits between the Bearings, along side the 10mm O-Ring when fitting Bearings into a TRAMPA hub when mounting the wheel onto 12mm Axles.

Over time, during the usage of your board, the bearings & spacers are put under a lot of force. Ultimately this force has to go somewhere... The Bearings use a Steel ring in their assembly where as the Bearing Support Spacers are made from Aluminum. Steel is much stronger than Aluminum & when forced against each the aluminum will loose out every time! This is what happens to your spacers between the bearings, the Bearings put force onto your spacers as a consequence over time the spacers shrink... With enough time its possible for an annoying rattle to start.... That's when you fit these 16.5mm spacers with the little 10mm O-Rings to prevent the rattles!! :-)

Mountainboard ABEC 5 Bearing 6001 2RS (12 x 28 x 8mm) Removable sidewalls with Embossed Logo

Bearing conversion Spacer converts 12mm Bearings to fit 9.525mm Skate & Spring Truck TiTanium Axles

Use this handy little part to convert 12mm TRAMPA bearings to fit onto 9.525mm (3/8ths of an inch) Axles... You will commonly find 9.525mm axles on Skate Trucks or Trucks with Titanium Axles. Simply slip the Conversion Spacer into your 12mm Bearing & then insert the Wheel back onto the axle.... Couldnt be easier.... :-)

The pressed aluminium is accurately made so it fits snugly into your bearing and tightly slides over the axle. The flanged Rim allows the axle nut to tighten without squashing the bearing wall, ensuring free spinning maximum performance from your bearings at all times. The sleeve can be re used over and over again but remember to replace your bearings regularly....

8mm Rubber O-Ring to fit in Bearings - 2mm Section x 8mm Bore NITRILE 70

This O-Ring should be fitted when a 9.525 x 16.5mm Bearing Support Spacer is fitted into the wheel assembly when fitting a wheel onto 9.525mm Axles. It fits alongside the Bearing Support Spacer, in-between the Bearings. This O-Ring prevents rattles from the spacer against the bearings. Over time, during the usage of your board, the bearings & spacers are put under a lot of force. Ultimately this force has to go somewhere... The Bearings use a Steel ring in their assembly where as the Bearing Support Spacers are made from Aluminum. Steel is much stringer than Aluminum & when forced against each the aluminum will loose out every time! This is what happens to your spacers between the bearings, the Bearings put force onto your spacers as a consequence over time the spacers shrink... With enough time its possible for an annoying rattle to start.... That's when you fit these little O-Rings!! :-)

HYPA Hub 3.75x 2 Inch - Any Colour you like!
