Best suited for cruiser bikes, vintage BMX builds, or commuter setups where a narrow, fast-rolling tire is preferred over wider, more aggressive options. The grooved design makes this tire practical for year-round street riding in variable weather conditions. The gumwall color option provides a classic aesthetic for period-correct builds or riders who prefer the vintage look. Not recommended for off-road use, skatepark riding, or applications requiring high-volume tires for impact absorption.\u003c\/p\u003e","brand":"TipPlusCycling","offers":[{"title":"27 x 1 1\/4 GW\/BK","offer_id":45048407294131,"sku":"31-805","price":10.8,"currency_code":"USD","in_stock":true},{"title":"27 x 1 1\/4 BLACK","offer_id":45048407326899,"sku":"31-818","price":10.8,"currency_code":"USD","in_stock":true},{"title":"26 x 1 3\/8 BLACK","offer_id":45048407261363,"sku":"31-505","price":9.8,"currency_code":"USD","in_stock":true},{"title":"26 x 1 3\/8 GW","offer_id":45048407228595,"sku":"TIPPLUS-tipplus_5024314032181-26 x 1 3\/8 GW - Sold Out","price":9.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8737\/2979\/files\/C638_1200x_ea3ddad7-db34-4e75-8a9b-ad68a6fb512b.jpg?v=1782677606","url":"https:\/\/time2shinebmx.com\/products\/tipplus_5024314032181","provider":"Time 2 Shine ","version":"1.0","type":"link"}
