The choice if you only need one chainring without a front derailleur. Without one, the chain could fall off in the worst case scenario. Thanks to a special design of the teeth, this doesn't happen with this chainring. The trick originally comes from the MTB sector, where the trend for years has been towards one chainring and things are getting even rougher.
You can find more information about the tooth profile in the pictures. Please note: this chainring has no climbing aids and does not work with a smaller ring as a combination! And shorter screws are required than for 2-speed chainring sets. You can find them here .
Why often only one chainring is enough and why it can also be a bit larger can be found here and here in my blog.
Details: machined 7075-T6 aluminum, adapted to the crank of Shimano's current Ultegra 8000 group and corresponding power meters.
These blades are extremely torsion-resistant. Available sizes from 46 to 58 teeth, black anodized.
Garbaruk uses an offset on these sprockets to make the chain line even better depending on the sprocket size: 56 has 1.5 mm and 58 has 2.3 mm inward offset teeth. They are also suitable for 12-speed chains and AXS flattop chains.
Other colors, bolt circle diameters and sizes - always only even number of teeth possible - on request. Due to the numerous options, please allow for delivery times if there is no availability in the corresponding size listed here.
Garbaruk chainrings are shipped free of charge within Germany!
