The \"OS20\" oversized designation indicates enhanced tubing in high-stress areas without proportional weight gain. The machined brake track delivers consistent stopping power for V-brake or mechanical disc-brake setups. At 359g, it balances speed with durability for competitive racing and training.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble-Wall 6061-T6 Aluminum Construction\u003c\/strong\u003e – Two-layer rim structure increases stiffness without proportional weight gain;
