The SLC3 is the third generation of the Super Light range. Unlike its predecessor, the SLC3 is no longer just a super-light climbing frame but a true all terrain master that also excels in aerodynamics.
Aerospace-grade materials are used to ensure the frame remains 'ultralight', with the medium weighing in at 699g unpainted. Ultra-layup technology ensures stiffness is not compromised, something which has been improved in key areas of the frame from the pervious generation.
The frame was designed with power transfer in mind, incorporating both asymmetric chainstays and an asymmetric bottom bracket to ensure the drive side of the bike can handle the strongest of climbers.
