Oo, did I feel some static?

Its been awhile since I posted and my exam havent finish yet (by next week), so since today I have some free time. Im going to give a quick info bout Scott's Marathon XC bike, Spark.

Hmm, so why do I categorize it as a Marathon XC bike instead of the usual full suspension race bike? Well my reason is because this bike is build for marathon usage, which means that its geometry isnt that stressful for the rider. Dont worry, you can still race on this bike because its one of the lightest 110mm full suspension out there (belive me there are lighter bikes but they can be categorize as not safe cause its build at a certain weight range). Oh did I forget that its also a good trailbike due to its carbon stiffness.

So enough intro and time to talk bout the bike:


Okay from the pic, its clearly that Scott decided to use a very conventional design. No bendy tubes, weird linkages or etc. The Spark uses a conventional faux bar linkage (pivot on the seatstay or Single Pivot Linkage), this simple design doesnt add unnessary weight and its proven by many manufacturers who used faux bar, those that should be noted are Turner Bikes.
But then you realise something, is that a piggy back reservoir shock? Yes you got it right, Scott as usual has designed their own shock with DT Swiss called the Nude shock which weights 240grm.



So whats so special bout the Nude shock? The advantage is, the rider is able to reduce the travel of the bike from 110 to 70 and dont forget that the shock offer a lockout feature. I belive the reason of the reservoir is so that when you reduce the travel (the height will reduce, hence better centre of gravity) the shock dampening wont be affected. Anyway the shock features a remote control called the TracLoc system which weights only 28gram, the rider would be able to change the travel with the use of his thumb .

Scott is famous for its CR1 carbon manufacturing process, but to make the Spark lighter, Scott engineers need a new method to make the bike lighter and yet without taking away important features. IMP is the solution. By using a patented process, Scott Engineers manage to produce the bike's headtube, toptube and downtube in a single process which has able them to reduce the bike weight without compromising the bike's overall strength. If you guys are a frequent reader of cyclingnews, Specialized rider, Christopher Sauser (a racer famous for not having unnessary weight on his bike) has his Epic custom made, his bike doesnt have a cosmetic carbon layer, the Spark has that feature too, its called Naked External Tubeset (NET) which help to save precious grams. So to sum it up about the frame, the whole bike feature Scott's latest IMP carbon manufacturing process except for the seatstay which is made from CR1 and also NET.

Below is a summarize of the difference between the bike frames offered by Scott for 2008:

Spark LTD Frame:
Scott Spark
HMX carbon fiber / NET / Integrated Seatpost
IMP top, head & down tubes
CR1 carbon swingarm / carbon cable stops & dropouts with replaceable hanger
Sealed aircraft bearings / optimised SLS kinematic / 110 mm rear travel
Frame: 3.42 lbs (1550 gr) + Nude TC shock: .53 lb (240 gr) Total : 3.95 lb (1790gr)

Spark 10 Frame:
Scott Spark
HMX carbon fiber / NET
IMP top, head & down tubes
CR1 carbon swingarm / carbon cable stops & dropouts with replaceable hanger
Sealed aircraft bearings / optimised SLS kinematic / 110 mm rear travel
Frame: 3.42 lbs (1550 gr) + Nude TC shock: .53 lb (240 gr) Total : 3.95 lbs (1790 gr)

Spark 15/20/30 frame:
Scott Spark
HMF carbon fiber / NET
IMP top, head & down tubes
CR1 carbon swingarm / carbon cable stops &
dropouts with replaceable hanger
sealed aircraft bearings / optimised SLS kinematic
110mm rear travel
HMF Frame: 3.64 lbs (1650 gr) + Nude TC shock: .53 lb (240 gr) Total : 4.17lbs (1890 gr)

Take note of the following:
Spark LTD lighter then 10 because of the integrated seatpost.
Ritchey carbon seatpost weights 260 gr / 0.57 lbs

The difference between HMF and HMX is its exclusively produced for Scott and offers 20% more stiffness and it has been reinforced to areas that need extra rigidity and at the same time to reduce weight. You save 100gr by buying a HMX frame.

Fork offering:
LTD - DTSwiss XRC 100mm
10 - Fox 32 F100RL (Black)
15 - Fox 32 F100RL (White)
20 - Fox 32 F100RL (White)
30 - Rock Shox Reba SL

So that's all, and take note that 08 models will be available in the US between October to January 2008, Scott is releasing the each model at different time.

So if you are a rider who loves to ride long distance and sometimes race and would love to own a lightweight full sus bike. Make sure the Spark is in your list.
