Okay, some impressions after couple weeks riding the Spark 29er.
Firstly, this is the base model "Comp",(poverty pack with low end components) - purchased with view to upgrade over time, but the frame is the same as its 2 upper specced alloy models (Team and Elite) and the same geometry as the 3 higher specced carbon models.
Still trying different stem lengths/heights and seat position.
Size is Medium, and feels quite comfortable, but does have more seatpost exposed than I'm used to.
Can only compare this to one other FS 29er I've ridden, so can't say if better or worse than other FS 29ers.
First impression is that this bike feels fast, and travels easily over terrain that in the past I would have hesitated to pedal through - gave me a sense of confidence that I suggest most 29ers give.
Bike did not feel heavy, (have not weighed it yet) but there are many areas/upgrades that you could save weight with this bike.
The fork is Rockshox XC 32TK with lockout- does the job, no glaring issues but is the 1st upgrade I would make.
The rear shock is X-Fusion RL with rebound adjust and lockout - after trying different pressures/settings, have found it works quite good - may keep.
This model does not have the Scott Twinloc feature of the higher specced models - but I lockout front/rear individually as I see fit, and usually left the rear unlocked as I found the suspension worked quite well with no obvious pedal induced bobbing (one of my major concerns on a FS bike).
Riding uphill was a strong area for this bike in my opnion - seems a good climber..
Riding downhill was fun - was able to bomb through terrain at speed.
Rear swingarm seemed nice and stiff,(not the suspension action) largish looking suspension bushes seem like they should hold up well - time will tell.
Seemed stable under braking, suspension remaining active enough, Scott's inboard direct mount rear calipers are said to aid in this area, but probably not as good as Trek's ABS system.
Good stopping power with the Shimano hydros with 185mm front rotor.
Front end seemed okay - has tapered head tube, QR axles, but would obviously be stiffer if had either 15 or 20mm axles.
Rims are Alex and have had no problems with them - will probably keep.
Steering felt neutral - not too sensitive or slow.
Bike tracked quite well, easy to ride through technical areas.
Schwalbe Rocket Rons work well with this bike - good alround tyre.
Shimano F/R derailleurs were just okay.
Plan to change to 1 x 10 or 2 x 10, and also get SRAM 10 speed gripshift as soon as they are available, (if world XC champion Jaroslav Kulhavy can win with them they must be okay).
Minor issue is the rearward facing seatpost clamp slot on the seatube - collects crud/mud and crapola. Annoying, as regularly change seatpost height depending on the terrain and grates/grinds when moving it.
Don't know why bike manufacturers put slot facing the rear, as it is a no brainer to have it facing forward for strength purposes as most weight/forces are directed toward the top of the rear seatube.
Will post further impressions as I have any.
Cheers
