Our SimWorks by Nitto seatpost was named 'Froggy' because of its frog-like appearance when viewed from the side. It is a classic Nitto profile. Available now in our lustrous polished silver and black finishes- we are pleased to offer 2 saddle offsets and post lengths. The role of the seatpost is to support the saddle in the proper position. Of the three points that the rider contacts (handlebar, pedals and saddle), the saddle position is the most critical element for creating a solid and efficient propulsion force. Therefore, a steady fixing force is required for both off-road or heavier riders. The Froggy post is uncompromising in its clamp security and rider peace of mind. The Froggy seatpost utilizes a two-bolt clamping system, which has the same structure as the NJS standard product- which Nitto has designed for bicycle races going back decades. This clamping style has the ability to secure the saddle rails with that force distributed across a broader surface area than a single-bolt style clamp. This offers no saddle movement and stays secured on even the most intense rides. Additionally, minor adjustments to saddle angle can be easily performed.
