Gossamer Triple MegaExo (2015 graphic)


Touring cyclists and mountain dwellers will be well served by the Gossamer Triple MegaExo. It has the same cold-forged 6061 aluminium construction and moncocque drive-side arm and spider as the Gossamer Standard and Compact, but with additional bolts to mount an inner chainring. Inner and middle rings are 30 and 39T, with a choice of 50 or 52T for the outer ring. A new No Pinch Bolt design for the non-drive-side arm gives an improved connection to the bottom bracket. The streamlined design of the Gossamer is enhanced by the highly polished gloss anodised finish.
