    Save your strength without sacrificing top-end.

    Considered a wide-range compact with its 46/30-tooth double, the Rotor Spidering Double Chainring gives you a greater range of gears for muscling up steep climbs without sacrificing top-end power when you're accelerating for the finish line or sprinting across flats. It's designed for riders on modern cyclocross and gravel machines preferring to run a double, as its low-profile design allows you to fit it on bikes with greater chainstay clearance for the larger tires becoming ever-so popular in cyclocross and gravel disciplines. It's CNC-machined from 7075-T6 alloy for weight savings and high levels of strength, with four mounted pins and machined switching lanes making the change from small to big ring seamlessly smooth. It directly mounts to Rotor's 3D+, 3D30, and Flow cranksets (43.5mm chainline) and works with both 10 and 11-speed chains.

    Subcompact for Rotor

    • Familiarity: I've used it several times

    I was looking for a subcompact setup for my Cervelo that came with Rotor cranks. This was the least expensive way of getting that low gearing. The inner 30 ring is great for long climbs in Colorado, and on the descents it seemed like I ran out of gears around 30mph.

    There isn't much detail available on how it is installed, so here details if anyone is interested. The Spidering has both rings already connected together. To install it you need to remove both of the current chainrings. Then go to a bike shop with the special Rotor tool to remove the existing threaded nut which will allow the existing spider to slide off. The 1 piece Spidering goes on and then the nut is tightened back on. It's a different assembly than a Shimano or SRAM crank but a pretty slick and simple solution.

    I couldn't get my FD as low as it should be, but with Di2 the shifting is still great.

    The bike looks great! Thanks for the feedback on the installation process. For everyone's edification, this is the part in question:

    Unanswered Question

    Do you sell a crank that is compatible with this (and preferably with a 24mm spindle so I don't have to also by a 30mm copatible BB)? If so, please provide a link to that product.
