Pardus Spark Sport 105 Di2 Racing 800 Aero Road Bicycle

The Pardus Spark 105 Di2 Racing 800 Road Bicycle matches the SPKG3 RS-105 Di2 platform, a carbon race bike positioned above Spark Sport and below Spark Evo. Its HS-EPS+ carbon frame and HS-HPT carbon fork are paired with Shimano 105 Di2 2×12-speed shifting. The drivetrain combines Shimano 105 R7150 derailleurs, an R7100 crankset and cassette, CN-M7100 chain and a BB30RL PF30 bottom bracket. The product title names Racing 800, but the confirmed SPKG3 RS-105 Di2 specification lists a different wheelset, so Racing 800 wheel details are intentionally not stated.

Race Gearing. Shimano 105 R7100 uses a 50-34T crankset with an 11-34T 12-speed cassette, providing compact road gearing with a 34T climbing sprocket. The R7150 rear derailleur is rated for a maximum 34T sprocket, matching the supplied cassette. Shimano 105 R7170 hydraulic disc brakes use RT70 center-lock rotors, with 160mm at the front and 140mm at the rear.

Fit and Service. The frame uses a 12×142mm rear thru-axle and flat mount disc interface, while the fork uses a 12×100mm front thru-axle. A fully integrated MVMT M-Silver A-Type carbon handlebar has 72mm reach and 130mm drop. The 350mm carbon seatpost uses 0mm offset and is Di2-compatible. Before replacing wheels, rotors or the cassette, confirm the Racing 800 wheelset's axle, freehub, rotor-mount and tubeless specifications because they are not provided for this exact configuration.
