PRIMO's 3 Spoke Composite Hub has a center set bearing position & because of its special '3.75/4 Inch Rim' means it is capable of fitting both 3.75 Inch Rim Tyres (8 Inch Tyres) & 4 Inch Rim Tyres (9 inch Tyres).
The 3 Spoke PRIMO hubs are assembled using just 3 heavy duty M6 x 30mm Stainless Steel Socket capped Bolts & M6 Nylock nuts. The Composite hub is very Strong but a bit Chunky. IMO its best fitted with 9 Inch Tyres or Any tyre using a 4 inch Rim.
Because of the extra size of this hub it is strong ebough for many applicatuons. When comparing the weight to the super slim design of the PHATLADS hubs (weighing just 184g), the PRIMO 3 Spoke hub weighing 282g does weigh in a little on the heavy side, but the 3 spoke'd solid structure is a timeless classic with an awesome reputation for not letting you down & is currently the only option hub that TRAMPA offers should you wish to mount 'Center-Set 9 inch Wheels'
Although slightly tighter to fit into than other hubs, TRAMPA's regular 28mm Bearings will fit perfectly into the Bearing housing of the PRIMO hub. As a top tip place the bearings in the freezer for 30 minutes before inserting them into the hub, the cold will cause the metal of the bearing to shrink & fit easier into the hub!
To fit the PRIMO 3 spoke hubs onto the TRAMPA TRUCKS you will need a special 12x 9.5mm Axle Spacer to allow the hub to position onto the axle correctly.
Bearings can be purchased at a discounted price when purchased with Hubs.
