Review: Useless - Be aware, this is not a full set of different sized spacers as the advert would indicate, especially since there were no options to select the size I actually needed. The size is also not mentioned in the product description and it mentions all sizes so it is an easy assumption that it includes all sizes, especially considering the price, which is not the case. For 170+ AED / $40 for 2 small pieces of plastic bushes it is ridiculous. I really don't know why they should need to be purchased separately anyway, ROCKBROS should send a full set of adapters with the suction cup mounts.
Review: They fit on my fox 36 perfectly great choice for boost bikes I haven’t had any problems
