The YESS MX-Y 20" BMX Race Frame is an evolution of the Type-X frame, but is unique in that it is setup for disc brakes (140mm rotor), and belt drive out of the box. Handmade in Canada, from a unique aluminum tube-set to shed weight, while at the same time improving strength and rigidity. Combine this with an integrated CNC machined headtube, custom hydro-formed front triangle with large weld areas for strength, and machined Euro bottom bracket shell and you have a race frame equipped for battle. Additionally, an asymmetric rear stay assembly allows quick chain/gear swaps, and also creates a full belt drive ready setup. A quick release seat post clamp is included, and 15mm CNC machined dropout slots are machined to fit the included 3/8" fully integrated chain adjuster (optional tensioner available).
