The suspension fork on the Sirius is a bit of a rare bird. The 100mm travel fork has a 15x100 axle and a straight 1-1/8th steerer tube. Most modern suspension forks are built around a 15x110 axle and tapered 1.5" steerer tube. You will be hard presse

<p><span style="font-family: Arial,Helvetica,sans-serif;">The suspension fork on the Sirius is a bit of a <em>rare bird</em>.&#xA0;</span></p><p><span style="font-family: Arial,Helvetica,sans-serif;">The 100mm travel fork has a 15x100 axle and a straight 1-1/8th steerer tube. Most modern suspension forks are built around a 15x110 axle and tapered 1.5&quot; steerer tube. You will be hard pressed to find an &apos;upgrade&apos;.</span></p><p><span style="font-family: Arial,Helvetica,sans-serif;">That being said, the suspension fork on the V.1 Sirius is still a useful tool for smoothing out the bumps.</span></p><p><span style="font-family: Arial,Helvetica,sans-serif;">To adjust air pressure, you&apos;ll need a specialized shock pump. Head on down to your LBS (local bike shop) and pick one up. The reason you need a shock pump instead of a normal air pump is because the air spring is both small and very high pressure. We set the fork to ~120psi in the workshop. This works well for a 170lb rider. You may need to add or remove air pressure based on your weight.&#xA0;</span></p><p><span style="font-family: Arial,Helvetica,sans-serif;">The lockout mechanism atop the right fork leg controls the amount of suspension travel. Dial it all the way clockwise (+) for a full rigid fork, fully anti clockwise (-) for full travel, or right in the middle for the goldilocks travel option.&#xA0;</span></p><p><span style="font-family: Arial,Helvetica,sans-serif;">Friendly reminder! The Sirius is rated to ASTM Condition 2 -- no drops greater than 12&quot;! Pop curbs, but don&apos;t hit that huge tabletop in your local bike park. </span></p>
