“Thanks for purchasing this Helmetor booster, you’re part of a very limited number of riders to own one so fit it, cherish it, share pictures of it and enjoy having a stiffer frame and more powerful brake.






Normally we ship products of this size as cheaply as possible for the benefit of you, the customer. However due to the uniquenes of these Limited Edition boosters - and the fact that we  won't be producing more of them - we are shipping them  as Tracked items/the most guaranteed service that the destination country allows. This will be reflected in the shipping price.


But HEY they are special! :)
