These right and left frame components have an integrated ISO disc mount located between the stays, and no eyelets. They are machined from 1/4" thick 4130 steel. The chainstay and seatstay tabs have a 58 degree included angle. The arced seatstay tab can be cut by the builder to accommodate angles up to 75 degrees. The tabs are 5 mm thick, and the dropout face and caliper mounting holes are the thickness of the stock material. The right dropout with the hanger installed is 8 mm thick. It is relieved on one side and is chamfered 45 degrees x 1 mm around the outside profile and windows.
- The right side accommodates a hanger that can be purchased separately here or from the Related Products below.
- Use our 160 mm ISO adapter, BK4003 or BK4003B, for a clean, integrated brake mount.
