While quite well-known for its ovalized chainrings used by the likes of Mark Cavendish and other top pros, Spain-based Rotor Bike Components‘ product offerings go quite a bit deeper than just those unique chainrings. However, we are going to discuss another one of the company’s niche chainring offerings – a consistently round one in this case.
The Spidering has been developed with the discerning gravel rider/racer in mind. CNC’d from a single piece of 7075 T6 aluminum, the Spidering offers a simplified platform for its 46/30 gearing. While a 30-tooth front ring might cause interference issues with chainstays, the Spidering eliminates such hassles because it does away with chainring bolts and the spacing they demand. The other added benefit to a one-piece set-up is a decrease in weight, with an increase in strength.
Rotor brass also told me that a major bicycle manufacturer is in discussions to spec the Spidering on an upcoming gravel-specific bike. Under threat of withholding a very tasty Spanish mixed drink made with pomegranate syrup, I was sworn to secrecy as to the name of that company.
