Hammer Track ISP
We are putting our aluminum frame production on hold indefinitely to make space for new projects. Stay tuned we have some rad stuff cooking! 👽
The Hammer Track ISP is everything that the Hammer Track AL is, but with the added weight savings and stiffness from a custom-butted integrated seat mast. This frameset is the top of its game for aggressive riding with our aero tubeset, machined headtube & dropouts, and oversized seat mast.

Integrated Seat Mast
The added stiffness from the oversized tubing and weight savings of an integrated seat mast makes a serious race machine. Our custom internal seat topper allows for 25mm of up and down adjustment and finishes things off with a clean and sleek look.

Modern Track Geometry
We took our knowledge and experience of bicycle design and revisited what it means to race and ride track bikes in this day and age. Our modern track geo maintains the aggressive and agile feel of a track machine and combines it with high speed stability and confidence.

Tapered Headtube
We designed a Weis signature headtube that elevates Aluminum as a frame material. Instead of unsightly external bearings, our headtube integrates high quality sealed bearings and houses an oversized and tapered carbon fork for confident and responsive steering.

Replaceable Face Dropouts
Our Weis signature dropouts have 304 stainless steel inserts to protect your frame and paint job from wheel swaps and gear changes.

Custom Select Tubing
We design our frames from the ground up. We carry a large selection of aerospace-grade 7000 series tubing to adapt to every customer and riding style. When we say custom we mean it, no one frame is the same.

Make It Your Own
Each frame we build is designed specifically for the customer. We do not duplicate paint jobs, so your bike is one of one. We will work with you to help bring your dream bike to life.
