The increased power transmitted via an E-bike motor is the ultimate test for chainring durability. It made sense therefore to develop Direct mount chainrings that are specifically designed to withstand the additional rigours of E-Bike use.Features:- Asymmetric tooth profile engineered for cross compatibility and functionality with different drivetrain systems- 9/10/11 and 12 Speed compatible (including SRAM T-Type and Shimano HG+)- Improved mud shedding capability- Improved chain retention- Better performance with extreme chain angles on modern 1 x drivetrains- Tooth profile allows for more chain wear before function is compromised, extending service life- Spiderless rings have a new leg design with improved strength and stiffness- Directly mounts to motor and replaces the full spider assembly for a lighter and cleaner looking set- up- Versions available for Bosch, Shimano and Specialized Systems- Designed to give 52mm chainline to suit 148 Boost frames- New for 2024 55mm chainline Bosch (Gen 4 Direct Mount) ebike chainring- Designed to withstand the demands of E-Bike use- Narrow/wide tooth profile designed to retain the chain without the need of a chain device- CNC machined in 1 piece from billet- CNC machined 7075-T6 aluminium provides the perfect blend of lightweight and strength- Hard anodised for an ultra-durable finish and increased longevity
