The solar is manufactured from the highest quality torayca carbon and is incredibly unique with its 100% monocoque 1pc construction. By using a mono-construction compared to a 2/3pc construction which most other brands use, we were able to make the frame even stiffer and stronger and create no weak or fatigue points. The solar frame is laboratory tested and proven to be insanely stiff and lightweight especially under high impact and stress tests. The internal cable routing allows for a super clean and stealthy setup. Tested by the Race rRceline team the past x2 seasons and now the frame of choice for many of today’s top riders, we could not be prouder of what we have created with the solar frame.Material: High performance TORAYCA carbon fiberSeat Post Size 27.2mmSeat Tube Length 238mmBottom Bracket Type Euro, threaded, BSA 68mmBottom Bracket Height 11.6" (EU)Wheel Size 20" x 1.75"Dropout Size 15mmHead Tube Angle 74.5°Seat Tube Angle 71°Head Tube Size (full int.)tapered 1-1/8” - 1.5” (120mm)Extras• full monocoque technology• internal cable routing• laboratory tested for superior strength andstiffnesscolor: Matte Black/Grey Matte Black/ Teal Galactic Purple GeometrySolar Pro LTop Tube Length (actual) 20.75” (527mm)Top Tube Length (effective) TBAChainstay Length (min.) 14.25” (362mm)Weight 1.160kg/2.56lbsRider Area TBASolar Pro XLTop Tube Length (actual) 21.25” (540mm)Top Tube Length (effective) 22.5” (571mm)Chainstay Length (min.) 14.5” (368mm)Weight 1.165kg/2.57lbsRider Area TBASolar Pro XXLTop Tube Length (actual) 21.75” (553mm)Top Tube Length (effective) 22.9” (584mm)Chainstay Length (min.) 14.5” (368mm)Weight 1.210kg/2.66lbsRider Area 540.7mm
