The RED XPLR AXS groupset features a power meter with thread mount chainrings, X-SYNC technology, and our lightest cranks. It is also available with direct mount non-power meter chainrings. Chainrings are available from 38T-46T and can be swapped simply. The crankset can also be upgraded to a power meter. Our hollow carbon crank arms feature a DUB spindle for durability and are available in 160, 165, 167.5, 172.5, and 175 mm lengths.
To allow for the wider tire clearance that most gravel bikes require, the minimum chainstay length for the XPLR drivetrain system is 415 mm. The XPLR drivetrain system would include the requirement of a UDH dropout and utilizes a wide crank spindle with a 47.5 mm chainline.
For 1x Road and All-Road applications where there is a desire for a wider gear range, the XPLR derailleur and cassette can be paired with a 1x aero crankset with a standard width spindle - but does require the chainstay length between 405 mm and 415 mm and a frame with a UDH dropout.
