Always on the hunt for Smoother, Lighter, and Faster, SLF’s Hyper System is evolving. Appropriately called the EVO system, the newest SLF products are split into three categories depending on your needs as a rider.
EVO Speed System
For most road riders, the new EVO Speed System will likely be the ticket. Like all of the new EVO products, the cage is stronger and boasts increased durability thanks to a U.S.-made cargon cage with 7075 aluminum mounting brackets. Machining tolerances are said to have been made even more precise so that the systems shift better than ever. All EVO systems include a 14t upper and 18t lower pulley which feature a two-step machining process to provide a specific look. Both those pulleys also spin on coated hybrid ceramic bearings for minimal drag.
The Speed System sets itself apart with a shorter overall height and narrower profile. There is also a small, color matched tab on the bottom of the cage to make it easier to push the cage forward for wheel changes. Available for Shimano, SRAM, and Campagnolo derailleurs, the EVO Speed System sells for $495 and includes a 6 year warranty.
EVO 1x System
For something a little more robust and for single ring drivetrains, the EVO 1X System is the right choice.
Built with a more robust carbon cage and revised narrow-wide pulley wheel design, the EVO 1X system is available for SRAM Eagle in mechanical and AXS, SRAM Force 1 and Rival 1, and Shimano XT and XTR 12 speed rear derailleurs for $495 each. Note that there is a new Oil Slick pulley wheel option that will perfectly match your SRAM cassette or other Oil Slick parts.
EVO Aero System
The fastest option will be the new EVO Aero System which is, well, more aerodynamic. Now more slippery than the prior version, a narrower profile and revised carbon front plate are the results of wind tunnel optimization.
I suppose more carbon fiber means more dollars, so this one is priced at $595 for the system, and includes a 6 year warranty like all EVO systems. Available for SRAM and Shimano derailleurs.
