Optimize your crankset.
Some of us build our bikes with every detail in mind from stage one, but others prefer to have a bit of room for tinkering as we go. Modular cranksets are a great place to start, for those of us who like to play with setups, and Rotor's Aldhu 3D crankset is one for giving us the reins to control our ride. Pairing nearly seamlessly with Rotor's Aldhu crankset is the 110BCD Aldhu Spider. This cleverly designed interface offers direct-mount features, with the added benefit of being able to run whatever 110BCD chainring you please with your crankset, and tweak them degree by degree until you're totally satisfied with the feel.
The DM Spider is crafted meticulously in Spain using top-grade aluminum and precision CNC machining. Its 110BCD enables you to choose either the enhanced oval Q ring or standard round chainring. Because the spider mounts to your spindle with a toothed interface, you'll find that it is easy to adjust the exact positioning, ensuring that you can find the perfect chainring position, if you opt for an oval ring, by rotating one degree at a time to dial in the perfect pedal stroke. This not only allows you to elevate your performance, but you can further tune your pedal stroke to reduce knee stress and possible injury.

I wonder if I can use this spider to mount Ultegra R8000 chain rings on an Aldhu or Rotor 2Inpower crankset. Matt
