The three top tube options accommodate riders from approximately 5'4″ to 6'+ depending on riding style: 20.75″ for shorter riders or those preferring tighter setups, 21″ for average height, and 21.25″ for taller riders or those wanting more cockpit space. Best suited for street, park, and trail riding where durability and responsive geometry matter. The adjustable rear end allows customization of chain stay length for dialing in handling characteristics. If you plan to run a rear brake, you'll need to purchase threaded 990 brake bosses separately. No gyro tabs, so this frame is designed for brakeless or direct cable routing only.\u003c\/p\u003e","brand":"S\u0026M Bikes","offers":[{"title":"Gloss Clear \/ 20.75\"","offer_id":45037217480883,"sku":"01-BTM2-GC-20.75","price":519.95,"currency_code":"USD","in_stock":false},{"title":"Gloss Clear \/ 21\"","offer_id":45656578719923,"sku":"01-BTM2-GC-21.0","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Gloss Clear \/ 21.25\"","offer_id":45656578752691,"sku":"01-BTM2-GC-21.25","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Limousine Black \/ 20.75\"","offer_id":45037217382579,"sku":"01-BTM2-BLKG-20.75","price":519.95,"currency_code":"USD","in_stock":false},{"title":"Limousine Black \/ 21\"","offer_id":45656578785459,"sku":"01-BTM2-BLKG-21.0","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Limousine Black \/ 21.25\"","offer_id":45656578818227,"sku":"01-btm2-blkg-21.25","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8737\/2979\/files\/01-BTM2_Gloss-Clear-b_f204b84b-2640-4484-9348-b4c94bc7e404.jpg?v=1783467226","url":"https:\/\/time2shinebmx.com\/products\/s-m-btm-frame","provider":"Time 2 Shine ","version":"1.0","type":"link"}
