Isaac Efficiency 08 WAS £1326.00

Isaac developed one of the very first, and certainly the most successful, aero carbon monocoque frameset designs of all time.It has been hailed as a classic icon.Isaacs Efficiency model is the direct descendent but with added benefits from half a decade of further development and manifold refinements. This is truly a super-light package. It has an aerodynamically developed form and internal cabling, so the faster you go the more you gain and vice-versa. Light, stiff, comfortable, beautiful and practical; it is everything that an Isaac should be.
