When we designed the GSX for narrow-wide chainrings, we had in mind the highest efficiency possible. And we delivered: the GSX is a super-lightweight chain guide with ultimately reduced rolling-resistance.
It's coming with X-GUARD, this heavy-duty bash guard is covering a quarter of your chainring: why just a quarter? Well the X-Guard is protecting.... just what needs to be protected. No fuss, no unnecessary weight. Just mount the X-Guard and forget it: it's here to stay.
