Made from A4 Marine Grade Stainless Steel, all of the nuts, bolts & screws used in a TRAMPA board have proven to be up to the challenge of holding everything together. Using Marine Grade Stainless Steel also means these Bolts will never rust on you! They can cope with the harshest of weather conditions & will laugh in the face of sandy/salty beaches or muddy freeride tracks - which can turn other manufacturers’ nuts & bolts into corroded rusting wrecks!
Wherever possible, we dip all our bolts into BLUE THREAD LOCKING PASTE, to ensure an extra strong & secure fix between the nuts & bolts.
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.
