With the change to the Spark, the 29er variant had lost the racey edge that I liked with a 26вЂі Spark (albeit, running a 100mm fork). But the Scale wasnвЂ™t really unto the rigours of Marathon and Stage Racing, as myself and other team mates put it through. The Scott Spark isnвЂ™t the all out race bike in their line up. But the positioning of the shock on the bike means I just canвЂ™t see it well enough to use them. Of course, there are more settings than that on an RP23 rear shock.

IвЂ™ve been surprised what IвЂ™ve been able to make it up, using the two main positions dependant on the terrain. There is plenty of suspension action there when needed for climbs. Now, the bike doesnвЂ™t compress heavily into corners, and it doesnвЂ™t feel like youвЂ™re just compressing the rear shock when climbing. I use the ProPedal lever to run it more open or with a lot of ProPedal, and using the Boost Valve for heavier hits. Since having the newly tuned Fox shock onboard, the Spark rides how I wanted it to. While the mounting position looks a bit odd, with the shock in the regular position, only a 500mL bottle can be run. Medium rebound tune keeps the shock under control for the given range of air pressures used with that suspension linkage. Medium velocity helps give the shock midstride support as well as stopping the shock from being too regressive when the Boost-valve opensД¤. A Firm Pro-pedal spring was fitted combined with a 225psi Boost-valve, this makes the pro-pedal platform very firm but still allows the shock to compress over high speed bumps or blow through its travel when needed.ДЈ. It makes the spring rate more linear as the bikes suspension system naturally ramps up.Дў. It has an extra volume (XV) air can to lower the compression ratio to 2.4 rather than 3.0 with the standard (STD) air can. I left a basic Fox RP23 with him and he made some thorough changes.ДЎ. Simon Glanville the Fox Service Technician at Sola Sport in Sydney, knows the action of the Scott Spark, and the racing I was using my bike for. So it was suggested that I try a custom Fox rear shock. But the open position was either too plush to be responsive, or too firm if the pressure was increased. The DT Swiss M210 rear shock just didnвЂ™t ride the same though. They were quite active, had plenty of travel available when needed, but could be locked out or made firmer right from the bars.

I really liked how the previous Sparks I owned rode. However, previous models had used the DT Nude shock, which could be open, in вЂTraction ControlвЂ™ or locked out. This unit comes with a lockout lever, which I had always found very useful on previous Scott Sparks that I owned. The mid range carbon Spark 29er came fitted with a DT Swiss M210 rear shock. The build kit remained the same, with a Shimano XTR group set, NoTubes ZTR Crest rims to Shimano and Dt Swiss Hubs, and a Fox 32 Float 29 Terralogic. In May, I switched from racing a Scott Scale 29er Premium hard tail frame, to a Scott Spark 29er Expert frame. Although many bike manufacturers go to great lengths to make sure they specify the right rear suspension unit for a dual suspension bike, an amount of custom tuning may still be beneficial. Getting a suspension unit, be it fork or shock, dialled for your bike and riding style isnвЂ™t something that you should take for granted.
