Standar ukuran ban

STANDAR UKURAN BAN

Berdasarkan referensi dari sumber www.sheldonbrown.com, The ETRTO (European Tyre & Rim Technical Organisation) atau ISO (International Standards Organization) adalah standar ukuran ban yang umum dipakai saat ini baik untuk ban luar maupun ban dalam sepeda. Pada kode ETRTO/ISO , dua angka di depan adalah menjelaskan nominal lebar pelah (dalam milimeter). Lebar ban yang dimaksud adalah lebar pelah bagian dalam. Kemudian tiga angka berikutnya menjelaskan diameter pelah (dalam milimeter).

Sebagai contoh untuk sepeda onthel pada umumnya memiliki ban standar ukuran 28 x 1 1/2 (ukuran umum) atau 40-635 (Kode ETRTO/ISO), dengan demikian bisa dikatakan memiliki lebar pelah 40 milimeter atau 4 cm dan diameter 635 mm atau 6,35 cm. Namun demikian ada juga sepeda onthel terutama jenis bak fiets atau transport fiets dan juga sepeda-sepeda produksi tahun 1960-an seperti misalnya Gazelle Seri 14, Gazelle Grand Sport, Gazelle Trim Sport yang menggunakan ukuran ban tanggung yakni 28 x 1.75 (ukuran umum) atau 47-622 (kode ETRTO/ISO).

Note: The ISO system uses two numbers; the first is the width of the tire or rim in millimeters (The actual tire width will vary a bit depending on the width of the rim. The rim width is the inner width measured between the flanges as shown in the diagram.). The second ISO number is the critical one, it is the diameter of the bead seat of the rim, in mm ("B.S.D."). Generally, if this number matches, the tire involved will fit onto the rim; if it doesn't match, the tire won't fit.
