One of the coolest things Cannondale added for the 2013 model year is the new SpideRing integrated spider and chainring. As the clever name depicts, the SpideRing removes the chainring bolts which increases stiffness and durability over traditional crank setups. On our pretty good but not perfect scale, it weighs in at 174 grams. Improving stiffness in chainrings improves shifting performance and reduces rubbing during sprints and climbs. All good things.
The first batch of 53/39T SpideRings arrived at CannondaleExperts.com today. We hope to have the 50/34T compacts later this month.
