  • Ashima AiRotor Brake Rotors Pro Review

    The AiRotors come in 140mm, 160mm, 180mm and 203mm sizes (soon a 185) in the ubiquitous 6 hole IS interface. They are made from 410 stainless steel that have a special high grade improvement, and they are heat treated to HRC 42. HRC is the Rockwall Hardness Scale, which is a hardness scale based on the indentation hardness of a material. An indentation hardness correlates linearly with tensile strength of metals. HRC 42 correlates to a tensile strength of approximately 194 ksi. Continue reading →

    Strengths:    no squeal, no fade, sexy

    Weaknesses:    none

    Bottom Line:   
    for the past year I've been running a 180 front and rear. I've never noticed any fade during a ride when paired with my shimano m596 brakes, with a mid density compound. I don't run sintered pads, and they haven't eaten through yet. They bite very hard. They were also about $18 each on ebay, so awesome value (genuine rotors, I made sure).

    Strengths:    Light, quiet, effective

    Weaknesses:    none observed

    Bottom Line:   
    I purchased a pair of these (160mm) for use on my Santa Cruz Blur XC Carbon. They had good ratings and were light... and I got them for a good price. They've been trouble free. I'm using them with Magura Marta SL Mag brakes and they've been quiet and stop well on an XC bike ridden for XC type riding.
    I'm happy with them and would buy them again in a heartbeat.

    Strengths:    Weight, colored rotor with chrome bolts, feel

    Weaknesses:    none

    Bottom Line:   
    I love this rotor. I got one first to try on the front... a 180 and am now ordering one for the rear as well. I have yet to be able to get these rotors to squeak or squeal or make any noise. They have a nice feel where you can tell they are there when you are pulling hard on the brake. They virtually weight nothing and come in cool colors, with really nice chrome mounting bolts. I'm sticking with these!

    Strengths:    Very light. Really good braking performance. Reliable. Excellent cooling and cleaning properties.

    Weaknesses:    Clearly a little finess is needed with a less robust rotor

    Bottom Line:   
    This is for a pair of rotors 180/160mm run with XT servo brakes.
    Light, reliable and consistent performance that exceeds the braking power created with the original XT rotors. They also run cooler on protracted descents and are appreciably lighter. Literally a case of "...less is more". They are a reasonable price as well.

    Strengths:    Very light weight, well made at a good price.

    Weaknesses:    Make a bit of noise, not the usual break howl just that you can hear them "working", probably due to the large number of cut outs in the braking surface.

    Bottom Line:   
    Performance, weight and price are excellent IMO

    What is best brake pad to use with Ashima Airotor?

    I am going to give Airotor a try. Anyone have any experience with these? I read review that you need to use 'sintered' pads? I have Shimano SLX on my 2012 superfly AL elite - stock pads seem in good shape so far - will start with what is on it. Any feedback from what pads did or didn't work ... Read More »

    Brake pad too far out on BB7 with 140mm Ashima Airotor

    I've been running BB7s with 160mm rotors for a while but just moved to a 140mm Ashima Airotor in the back. The brake pad is too far out relative to the rotor (by about 2 mm), so the outer edge of the pad is not touching the rotor at all. What's going on? Maybe the rotor is undersized (sorry, should ...

    KCNC Razor vs Ashima Airotor

    I currently have KCNC rotors but am curious if anyone has used both of these and what your impressions are. Both are fairly light with the KCNC's being a little lighter at about 75g for a 160 rotor. At this point, I'm not stressed about the 10g difference but rather am tired of dealing with so ...
