Unofix Racer Spacers
. All the Unofix deep section fixie wheels are designed to fit standard rear fixie frames with 120mm spacing. If you have a racer frame the spacing is 130mm and you had to squeeze in your dropouts by 10mm to make them fit, putting added stress on your stays. NOT ANY MORE
Unofix introduce these 2- 5mm racer spacers to slip on the axle to space them to 130mm. You also get a pair of slimmer wheel nuts included.
