Isaac Sonic SXL Frameset -- The Isaac Sonic has been developed by reducing the esential material to a minimum for ultra light weight. It employs 3K layer carbon in its true monocoque frame and fork.
The result of this new moulding is a frame weight that is approximately 880 grams in a size 54. The thinner more aerodynamic headtube while retaining the dual diameter steer tube for strength provides an inspired ride. The frameset include an Isaac 31.6 diameter carbon seatpost.
Strategic reinforcement with Ultra-High Modulus carbon 440 GPa reduces the quantity of carbon in the stressed areas of the structure. Finite element analysis insures that the structural integrity remains intact.
This design has been conceived to resist flexing and allow forces to flow, uninterrupted, throughout the monocoque structure - for unprecedented performance in such a low weight frame.
In all of its frames, Isaac utilises large diameter tube sections with large radius transitions. Smooth curves allow the load forces to flow and be dissipated.

Isaac Impulse Frameset -- Isaac is unique in the ever assimilating world of carbon fiber frames. Their principles start the oversized headtube that incorporates a 1 1/4" bottom bearing to better deal with the stresses at this junction and continue throughout the frame design.
The quality of the carbon is extremely important to Isaac so their Torayaca T1000G and M30S Carbon Filament is a modulus carbon where the strands are clean. The result is the best tubing for frame creation because it has the strength needed to support the rider and deliver the stiffness that translates into excellent acceleration, and thanks to the vibration dampening long carbon strands provides the magic carpet ride that is the hallmark of a handmade carbon frame.
If you're ready to break away from the pack then you're ready for the Isaac Impulse.
