In the bike industry fashion is determined by the mud on your shorts and dust on your shoes. Yet, there is something undeniably satisfying about a freshly tailored suit, we designed the all new Rainier Dropper Post to add that custom tailored feel to your bike. The past version of this post is known for its consistency and reliability. While maintaining those qualities, this new iteration focuses on fitting more bikes and providing refined adjustability for the rider.

Our travel adjust system allows for a total of 30mm travel reduction in 5mm increments. If you were riding that line between a 170mm and 200mm dropper you can now fine tune the perfect fit, (like finding the perfect chamois that holds you close but doesn’t create an excess of muffin top).

The redesigned Rainier is significantly shorter than our other posts. We scrubbed overall length of the post by minimizing the size of the bottom actuator and shortening the lower tube. Overall length reductions vary by travel but we were able to knock out 27.5mm of overall length from our 125mm size. Combining all of these changes means this version of the Rainier can fit into more bikes while also maximizing the amount of travel available.
