Yeti SB 66 Alu Frame

The visually stunning lines and sculpted tubeset of the SB-66 will capture your attention like love-at-first-sight.  As you move in closer for a better look you’ll begin to notice this isn’t just another single pivot trail frame but and an innovative suspension design called Switch Technology.  The oversized main pivot actually contains a second pivot (lower pivot of the swing arm) that is offset within the main.  This eccentric mechanism switches direction as the bike moves through its travel creating an optimized wheel path without unexpected spikes or wallows.

At the beginning of the travel the eccentric link is rotating in a rearward direction, guiding the lower pivot of the swing arm rearward.  This counter-clockwise motion coupled with the initial rearward wheel path creates an excellent pedaling platform, making the SB-66 pedal and climb crisply without sacrificing small bump sensitivity.  The mid stroke has a flat linear shape, creating a large “sweet spot”, allowing the suspension to react better to bigger hits.  Once the travel reaches about 100mm, the eccentric link starts to rotate in the forward direction.  This means the rate at which the chain stay grows drops off quickly, allowing the suspension to work independently of chain forces. Because the suspension isn’t being impeded by chain growth in the last third of the travel, the smooth feel in the middle continues all the way to full compression without a harsh bottom out feeling.

Every detail on the SB-66 screams, “Ride me!” From the Kashima coated Fox RP23 rear shock to the unibody frame construction.  Even small details like an externally splined BB shell, tapered headtube and Enduro Max bearings make all the difference.
