Redshift Sports ShockStop Pro Race Suspension Seatpost

Unlike plush, long-travel posts designed for comfort-first riding, the ShockStop Pro Race is engineered for efficiency. It provides a firmer, more responsive feel that absorbs high-frequency road buzz and sharp impacts without feeling like you are bobbing or losing power during hard pedaling efforts.

Yes, the post features user-adjustable stiffness. You can swap or tune the internal elastomer and coil setup to dial in the exact level of firmness you prefer, allowing you to balance compliance with the responsiveness you need for racing or fast gravel riding.

The ShockStop Pro Race comes in a 27.2 mm diameter. If your bike frame requires a different seatpost diameter, you will need to use a high-quality seatpost shim to ensure a secure, slip-free fit.

Because the suspension utilizes a linkage design, your saddle position will shift slightly as the post compresses. However, the 20 mm of travel is subtle enough that most riders do not need to alter their static saddle height significantly to maintain an efficient pedaling position.

Yes, the clamp is designed to accommodate both standard 7mm round rails and 7x9mm oval carbon rails. It is a versatile clamp system that works with the vast majority of modern performance saddles.

The ShockStop Pro Race is rated for a maximum rider weight of 242 lbs (110 kg). This limit accounts for the rider's body weight plus any gear carried on the bike.
