Rollerblade brake for inlines

Brake for Rollerblade Lightning 90 W inline skates. I was shipped a different pair of skates in this box by accident and the break was not compatible. According to the website this brake is also compatible with RB XL, Macroblade 90, Sirio 90, Maxxum and Tempest 90 W skates. Note 90mm wheels are wider than the common 80mm wheels - this brake will not give you ground clearance if your wheels are less than 90mm (I tried)
