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
Use the exact tooth combination and derailleur application listed above. The official TRiPEAK support library includes the AOPW-AERO Road installation document. Follow the document for your model’s mounting parts, chain check and alignment, then check clearance and shifting 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.
How do I choose this AERO or EVO version?
Match the listed derailleur model and tooth combination first. This listing’s tooth count is part of its fit. Compare the other AOPW versions and use the official model instructions for installation.
