Hi, I've ridden the Spark quite a bit. Currently the owner of the new Trance 29'er and my neighbor owns the Spark. In terms of comparing OUR bikes, he has narrower rims and more trail focused tyres on, my bike came std with wider rims (30mm internal) and DHF / DHR tyres which grip like its nobody's business, but are a bit slower to pedal to the top.His has rmote lock out, mine is analoqgueMy bike came with DVO's Topaz shock that has a piggy back Other than that they are both carbon frame, dropper posts, wide bars, 1x12, etc, etc. If I could answer your question as short as possible. The Spark is closer to a stage / marathon type trail bike, where the Trance leans more toward being a proper all mountain bike. I've ridden the new alu Trance with a normal shock and even that one felt more like it wants to play than cover miles. It is still a good miles bike, just feels a bit more comfortable on rougher stuff. I'm sure either will be great, so best would be to ride a new Trance and then decide from there.
