From side view pics, the HT angle on the Sparrow looks about 58 degrees and fork offset appears close to 2". Assuming a wheel diameter of 19.2", that's equates to about 3.6" of trail - which is about twice the DF standard and over 3 times more trail than I like to see. The problem, is that many 'bent manufactures' create an otherwise suitable design, then butcher the handling by installing pre-made DF forks (obviously to cut cost).
