* 100 mm  Modern front hubs.
  126 mm  Rear 6- and 7-speed (road).
  130 mm  Rear 7-speed (MTB) and 8- 9- and 10-speed (road).
  135 mm  Rear 7- 8- and 9-speed (MTB)

  Most mountain bikes are 135mm but there are still some older 
  130mm bikes around. In some cases it will be 132.5mm which can take 
  either 130mm, or 135mm spaced hubs.

  6- and 7-speed hubs generally use 126 mm spacing, while 8-/9-speed hubs use 
  130 mm (road) or 135 mm (MTB/Hybrid).
