The Wolf Tooth Bolt-On Seatpost Clamp (34.9mm, Blue) is a premium, USA-manufactured bike collar designed to secure your seatpost with consistent clamping force while providing a clean, vibrant aesthetic. Its 34.9mm diameter fits mountain, gravel, and road bike frames designed for a 31.6mm seatpost size.
Key Technical Specifications
Clamp Diameter: 34.9mm (Fits frame seat tubes measuring between 34.4mm and 35.4mm to account for paint and manufacturing tolerances).
Material: CNC-machined 6061-T6 aluminum body with a blue anodized finish.
Hardware: M5 stainless steel bolt paired with an integrated spherical washer and a cylindrical anchor barrel.
Weight: Ultralight design at approximately 19 to 20 grams.
Installation Specs: Requires a 4mm hex key with a strict maximum torque rating of 6 Nm.
Clamping Height: 13.5mm.
Engineering Benefits
Self-Aligning Design: Features a custom spherical washer and barrel interface that ensures threads are always perfectly aligned. This design prevents bolt binding, eliminates hardware fatigue, and guarantees linear clamping pressure.
Dropper Post Friendly: Distributes forces evenly around the structural tube, preventing localized frame pinching that can cause dropper seatposts to stick or slow down.
Frame Safety: Approved for use on carbon fiber, steel, titanium, and aluminum frames. Fully compatible with newer carbon Ibis frames (e.g., Ripmo V3, Ripley V5) but not compatible with older carbon Ibis frames using a proprietary curved collar.
This seatpost clamp combines precision engineering with durable materials, making it an excellent choice for riders seeking reliability, performance, and sleek design.
