    If they were the same price you should get the DT Swiss 460, but I believe the Alloy wheelset is being discontinued so you ought to be able to find them at a discount. The Alloy rim is a box rim,...

    What power meter are you using? Torque zeroed? Same tire pressure, room temperature, weight, inner tubes?

    I haven't found that particular calculator to be accurate at all, and I compared it with a calibrated on-bike power meter.

    Many riders find a big difference in their "indoor" and "outdoor" abilities. The difference is large enough that indoor and outdoor efforts often aren't consistent with each other anyway.

    Unfortunately, drive train losses can vary with the chain ring and cogs used. With a crank-based system you can see differential loss from maybe 3% up to maybe 5-6%. The Power Tap is "closest" to the...

    Fortunately the stack and reach for the bikes were similar, and he had been using a forward seat post, so he could replicate his "touchpoints" (saddle, bars, and pedals) relative to the BB. He...

    Can you install compatible BBs on both bikes? If so, leave the Vector S on the crank and swap the cranks.

    Your own results seem consistent with the observation that L/R balance is not constant -- it varies with cadence, pedal force, power, and fatigue.
