Description

Aldhu 3D+ Crankset Package

In a world of pre-configured bikes and dime-a-dozen drivetrains, the Rotor Aldhu 3D+ Crankset Package is a breath of fresh air. It brings flexibility to the table for complete control over your crankset, from crank length to chainrings, and further — to completely adjustable Q-rings that allow you to hold the reins on your power and utilize your energy to the max. Each component of the Aldhu 3D+ Crankset comes to you with the highest standards possible from their Spanish facility, giving promises of precision and meticulous care with thanks to aeronautic aluminum, and precision machining.

The Aldhu 3D+ crankset is the product of a wealth of knowledge and data from Rotor's elite team of engineers, and professional athletes. It begins with the 3D+ CNC machining of 7075-aeronautic aluminum to ensure unmatched rigidity from spindle to chainrings so you can take control on the roughest roads. It allows for full modularity, with two different 30-millimeter spindle options that offer stiff power, and room for rim brakes or disc brakes. You'll find a wealth of options in arm lengths and chainrings so you can optimize your crankset for any day of riding, and swap chainrings when your training beckons you to reach for more resistance. It can be run with either the oval Q-rings we spec here, or circular rings for those who prefer to air on the side of tradition.

This build of the Aldhu comes equipped with two oval Q-rings with Optimum Chainring Position (OCP) technology that enables you to tweak your chainring position degree-by-degree. This enables you to utilize the most powerful part of your pedal stroke to propel you further, and allow a touch of relief through your weakest points. While adjusting the Q-rings to the optimum position is no doubt easier when you've trained with power and have the data to determine your OCP, we find that its easy to determine the position by feel. If the pedal stroke feels smooth all the way through, you can be confident that you're in the right place, however if your pedal stroke seems to flow with ease through the beginning and meet you with harsh resistance at the bottom, we'd suggest adjusting the ring a degree or two counter-clockwise. Inversely,if your pedal stroke is packed with resistance through the down-stroke, only to let up at the bottom, give it a turn clockwise. A little bit of trial and error should be all it takes to maximize your power on the bike.

This will work for shimano pressfit bb? Whats the weight for the 175mm compact? Thanks folks!!!

Hey Jose! Your Shimano bottom bracket won't accommodate the 30mm spindle on this crank, but Rotor makes a BB that would work perfectly. Check out the link and item number below for the 4630 BB. Feel free to respond to the email that I just sent you if you have any questions! Thanks! https://www.competitivecyclist.com/rotor-press-fit-4630-bottom-bracket?skidn=RTR001Z-BK-BBR&ti=U2VhcmNoIFJlc3VsdHM6NDYzMDoxOjI6NDYzMA== RTR001Z-BK-PF3
