R&G Offset Cotton Reels directly replace the O.E. chain adjusters on the rear swingarm, off-setting the cotton reel mounting point from installed directly into the swingarm, instead into a specially machined metal bracket. Offering the best of both worlds in terms of crash protection and functionality with the ability to use the R&G Offset Cotton Reels bobbins as paddock stand bobbins for tire / chain maintenance as well as offering crash protection to the rear wheel components. R&G Offset Cotton Reels are designed to replace the O.E.M. chain adjuster blocks, offsetting the cotton reel installation point further rearward, this is because, under extreme riding condition, the O.E.M. / aftermarket exhausts have been known to impact with a standard sized (traditionally swingarm mounted) cotton reel as well making it easier to locate and lift onto a paddock stand.
