IQON BLACK bearings don't follow standards - instead, they are setting a new one. Combined with Decode frames these bearings with integrated bearing boss allow for various different setup options at incredibly low friction. Still using conventional frames for whatever reason? - seriously, WHY? - Decode bearings got you covered anyway. Simply turn the bearings inside out, put in the included shorter spacers, and off you go. This set includes 16pcs of bearings and 8pcs 7,25mm spacers. (these are the ones for Non-Decode frames with integrated bearing bosses) #AUGMENTEDMOBILITY
