What Makes Structure's Pivots So Special?

How was Structure able to build a full-linkage suspension platform that stands up to the toughest rides and riders while offering a 250-hour bearing service interval?

It's all about thoughtful engineering. Come along for a closer look. 

Our front linkage system looks complex at first, but is actually very similar to a rear four-bar system. In fact, it uses the same hardware and bearings as our rear main pivots.

Removal of the front control arms reveals details that make our pivots extremely durable. We start with large, strong, 17 mm collet-type axles.

Removal of the axles is simple and gives a view of the bearing caps, which provide precise spacing between suspension arms, bearings, and frame. 

Each of the main bearing caps comes with an x-ring seal to keep water and dust out of the bearings, which is key to bearing longevity.

Removal of the 30 mm main pivot bearings reveals alloy through-frame inserts and wide spacing between bearing seats. These features prevent distortion of the pivot system and uneven side-loading of the bearings to increase system stiffness and bearing durability. The eccentric bearing cups (pictured above; 2 sets provided with each bike) of the upper control arm can be installed in one of four positions and reduce brake dive versus telescoping forks by 17%, 22%, 33%, or a whopping 41% to further enhance the stability of our linkage system, which offers the vertical travel equivalent of a 170 mm telescoping fork and 25% greater lateral stiffness.

We built our pivots to last and provide smooth, confidence-inspiring performance for the life of each bike. Last, but certainly not least, anyone who can service rear suspension can easily service a Structure SCW1. Why sweat the smallest details? Because we'd rather be riding than wrenching. Wouldn't you?
