TRiPEAK Asymmetric Oversized Pulley Wheel Kit for SRAM XPLR E1 1x13 – 14/18T
The TRiPEAK asymmetric oversized pulley wheel kit for SRAM XPLR E1 1x13 uses the listed 14/18T tooth combination. Check the exact rear derailleur model, generation and cage designation against the specification below. A shared Shimano, SRAM or Campagnolo name does not make different derailleur versions interchangeable.

Choosing this version
AOPW means asymmetric oversized pulley wheel. The larger pulley changes the chain’s path through the derailleur, so tooth count and model-specific mounting parts must match. AERO and EVO versions are separate product designs; choose by the supported derailleur and supplied parts rather than assuming all AOPW kits share the same fit.
Installation checks
TRiPEAK’s official AOPW upgrade article describes retaining the original derailleur cage without requiring a longer chain. It also asks installers to check that chain length is appropriate for the bike’s setup. Follow the matching TRiPEAK installation manual for the upper/lower pulley positions and mounting parts, then check shifting and clearance through every gear.
Will it fit a different generation of the same groupset?
Only the models listed in this product’s specification are supported by the information here. Road AXS, XPLR, Eagle and T-Type are distinct applications. Check the full derailleur code and cage length before choosing a kit or wheel set.
Why use an 18T lower pulley?
TRiPEAK’s 18T-versus-11T explanation describes a gentler chain-bending angle with the larger pulley. The asymmetric mount accommodates the larger wheel in the supported original derailleur arm. Read how the AOPW upgrade works for the design and fit details.
