Carbon-Ti’s new X-Monoring Titanium single chainrings replace the crank’s standard spider and are designed for Specialized carbon cranks, SRAM X0/X9/X7 and Cannondale Hollowgram SL and SI.
They’re available in 32/33/34/35/36 tooth counts and are compatible with all 10 and 11-speed groups on the market. By replacing the spider, it saves even more weight, and they say the titanium is far more durable than alloy chainrings. Prices and weights weren’t available.
They’ll come with mounting kits similar to this, you just shouldn’t need the bolts.
This is their double ring set up but gives you an idea of how they look on the cranks.
Their new X-Hub MTB SL hubs come in at just 108g front and 196g rear. They get a taller flange than before to provide better angles for 29er wheels.
They saved weight by doing a little extra machining on the outside ad giving it an oversize 7075 alloy axle. QR and 15mm front / X12 rear axles are available.
