24 x 1 (Straight Schrader Valve) 24 x 1 3/8 (Fits most 24″ wheels. A 1 3/8″ Inner tube fitted with a straight schrader valve) 24 x 1.9 (for Sunrise Medical Quickie mountain bike wheels fitted with a straight schrader valve)
Im pretty sure it will be the 24”x1”. They’re really slim, cheers @Kezo. @DD good idea about the bike shop, why pay more for a specialist wheelchair shop. 👍
