meh, I am 6' 2" 21's always feel sluggish for me. I rode a 21" barcode for a long time and it always felt kind of slow. If you ride a lot of trails its fine, but if you are more interested in street/tech stuff I would suggest going a bit shorter. I rode a 20.5 stricker for about a year and recently aquired a 20.6t autopilot. Both are very responsive, good for spins and mashing around obsticles.
