    the older specialized chart does confirm very high efficiency at high rpm. it also suggests that the efficiency should be higher at...

    cool my guess is, however, that the system is not 84% efficient at 100rpm. more likely it’s just not outputting quite the full 315/320...

    i’ve very much enjoyed inflating with the cliks. it’s so much factor and more satisfying! on both my road bikes. air loss is very...

    an interesting note in a review of the new firmware for the full power levo, perhaps explaining why 0/100 on microtune is not really 0.

    i think the varied efficiency of the motor (let's call it 70-80%) and the inability to measure this property directly make it difficult...

    ok, i have no idea how i achieved that u shaped result! what the heck! going back to the data, if you consider support factor as the...

    so, if we believe these electrical power values are fairly typical and repeatable, AND we believe specialized's mechanical power...

    here's what i think is happening. when specialized changed to "ease" from "assist" they changed one very significant thing - the...

    i also have to say … realizing how much more powerful this bike is than my creo was, i’m kind of wondering if the ideal replacement for...

    i think testing a fairly powerful bike like the SL2 with a range of E from 40 to 100 will likely bump up against the edge cases of speed...

    I’ll believe that when I see it documented on a long-ish steady state effort - preferably a shallow climb - at similar cadences across a...

    according to the 40/100 chart you posted, the average Pm/Pr between 50 and 200 watts Pr is 1.5. 1.2x after efficiency. not too far off...

    mschwett replied to the thread Turbo Vado 2 4.0 or 5.0 or 6.0?.
    ok, this starts to explain things. toss all the values where Pr is < 50 or > 200, they’re likely not steady state values in this sample...

    nice the 1.6x is a bit higher than you’d expect 40% ease to deliver on an SL2, and it’s quite linear. “2.7x you” at 100% ought to be...
