INpower 3D+ 110BCD
The way you exert power throughout a single pedal rotation varies in force, even more when you are seated, standing, sprinting or pacing. Manufactured in Spain from 7055 aluminum through state-of-the-art CNC-machining, the INpower 3D+ 110 BCD features sophisticated metrics to interpret your data through user-friendly software and advise you when to turn up the pace, ease off the pedals, do another interval or call it a day. Seamlessly integrated inside a compact crank axle, the INpower 3D+ 110 BCD is protected from shocks, crashes and outside contaminants, plus it allows you to maintain your bike’s sleek, elegant aesthetics.

User Software Manual
Get “more” out of your Q-Rings
“MAS” stands for Micro Adjust Spider and means “more” in Spanish. That’s what this technology is all about: more adjustability to further optimize your Q-Rings. Additional bolt holes allow for intermediate positions between a Q-Ring’s existing Optimum Chainring Positions (OCP).
A standard crank and Q-Ring combination offers approximately 5 degrees of OCP adjustment. MAS together with Q-Rings offer half positions of approximately 2.5 degrees of OCP adjustment. This means you can micro adjust the orientation of your Q-Rings to fine-tune your pedal performance.
Why Q-rings? Biomechanical studies indicate that the effort made with Q-Rings becomes a greater performance and pedaling feeling
more rounded and smooth due to their ability to make a better use of the strongest muscle groups while they also compensate the dead spot in pedaling. Q-Ring-Round Ring Comparison Far from feeling unusual, a Q-Ring feels much rounder than a round ring.
A spinscan analysis visualize a cyclists power delivery, with a bar graph indicating the variation from maximum to minimum
output and a polar graph showing the rotating shape of the power profile. By comparing the left hand Round chainring spinscan
and the right hand Q-Ring spinscan below, one can see that Q-Ring graphs are clearly smoother (less variation in torque in the bar graph)
and fuller (less of a peanut shape at the weakest point). Spinscan When one projects a polar plot of a typical spinscan over the varying drivetrain resistance of a 53t Q-Ring during its rotation,
the value of a Q-Ring is clearly visible: Maximum power is met with a “56,5t” Time trial sized chainring diameter and minimum power is met with a “50,4”
compact size chainring diameter. This variation creates the “perfect spin” we all aspire to, that simply isn’t possible with round chainrings.
This is because Q-Rings compensate for the weakest zone of the pedalling stroke and maximize use of the most powerful zone. Key benefits (based on ROTOR study)
All Q-ring TT’s were faster, with an average gain of 1.6 sec and 0.7 km/h (1.8%).
All Q-Ring TT’s generated more power, with average increase of 26.7 W (6.2%)
Reduced oxygen consumption and heart rate in submaximal tests
An immediate performance increase on switching from round rings to Q-Rings
An immediate performance reduction on switching back to round chainrings
It also appears that the more effort a cyclist exerts, the greater the benefit of Q’s
