The New Piramide Rims from Fly bikes use a very strong pyramidal structure to keep strength high but weight down and utilising a Triple pinned manufacturing process they have made these rims some of the Most Affordable Aftermarket Rims about 

With 2 Versions available Fly have your sorted whatever your style is:

 Piramide 17 low profile is brakeless Version that is Ideal for the Front but can also be used on the rear if you don't run brakes& 

Piramide 21 medium profile is slightly taller that also has a Flat sidewall for Brakes or if you want a slightly stiffer rim to take a bit more load, which the Rear wheel often needs..

Both Can Be run front or Rear but our recommendation would be 17" (Front) and 21" (Rear)

but hey its your bike
