Good to hear that you are satisfied Micke, and that it is pretty fast on the track. I have been riding a Chinese Carbon HT for three years and have been very satisfied. Would like something that is a bit more slack but still with lots of speed. Looks like the M06 frame could be the one. According to the Scott sizefinder I should go for an XL in the Spark 900RC. The XL is a little bit larger than the 21" M06 so that should suit me perfect.
Thanks for the inputs from the rest of you too

Hi Micke

How tall are you and how is the fit for you 17,5"? I am in doubt if I should buy a 19" or the 21" (height 190cm)
Have you taken it for a "real" ride and how does it feel?
