S1000RR R&G SPOOLS 2019+ Are they cotton reels or spindle sliders? Well they are both really!! The Cotton Reel is mounted to a special, black-anodised aluminium bracket (included with the kit). The product will give protection to the swingarm area in most crashes. Also the bike can be lifted on the Cotton Reels, using a paddock stand with hooks (suggest R&G code SH0001). For rear wheel removal, you can take the Cotton Reels out of the aluminium blocks and insert them into the paddock stand bobbin screw holes.
