Engin Cycles Dual Bolt Seat Collar
The Engin Cycles Seat Collar is machined in house down to the titanium bolts to ensure solid grip on your seat post without binding the internals of delicate dropper posts.
Engin's dual bolt design helps ensure an evenly distributed clamping force over the largest possible area to reduce stress on dropper posts and frames, and eliminates the need to over-torque fasteners to prevent slipping. Made from 6061 Aluminum, all collars have a plated finish, and feature formed threads to prevent stripping.
Engin Seat Collars are made to the highest degree of precision in house to ensure the most evenly distributed clamping force over the largest possible area. This reduces stress on frames and seat posts, and eliminates the need to over-torque fasteners to prevent slipping. Custom made 6-2-4-2 titanium fasteners are durable and corrosion resistant while keeping the overall weight down to 29g for a 34.9 collar.
Our collars have a stack height of approximately 1" - ensure your seat tube has enough space, keeping in mind some frames will require sanding paint for proper fitment. Use a torque wrench when installing this seat collar, tighten each bolt a little bit at a time, and bring each one to 5 Nm max.
