What are the differences between the three sizes and which should I choose?
The 50-34t compact is best for climbing, 52-36t mid-compact for varied terrain, and 53-39t standard for flat/sprinting. Choose based on your riding style and local terrain.
Does this product include the crank arms or just the chainrings?
This is a chainring set only. It does not include crank arms or bolts. You will need to install them on your existing crankset.
How long does shipping take and do you ship internationally?
