Offset Cotton Reels by R&G.

Cotton reels are oversize paddock stand bobbins. Almost a mini version of R&G’s crash protectors the cotton reel is constructed of the same high density polyethylene (HDPE).  Doubling up as paddock stand bobbins, they allow the motorcycle’s rear wheel to be lifted with the use of a paddock stand, in order to carry out cleaning or chain lubrication, or for storage. 

Offset Cotton Reels are a mix of R&G spindle sliders and cotton reels, where there is no threaded mounting provision on the bikes swingarm for standard cotton reels. The brackets for the ofset cotton reels are machined from aluminium and replace the standard chain adjusters, and they offer increased protection for the swingarm and core swingarm components from damage in the event of a crash, slide or drop.
