are you able to stand up on the kickr without any drawbacks ? if i stand up the back wheel slips even when i have a bkool block and a brick under front wheel - i do like the sound of directdrive - is there any other pluses or negatives ?
No drawbacks, at all. The kickr is extremely stable, doesn't wobble unlike the Bkool Pro, which can feel like its about to topple unless you keep upper body still whilst off the seat. Obviously no wheel-spin-direct drive. Downside, its is disadvantaged against the pro for speed, so not a level field for competing. It has an accurate power meter, bkool over reads by 40-50 watts for me. Oh and cost, its a lot more than a bkool pro
