  • Low-profile alloy crank.
  • High-polished arms.
  • Steel chainrings with patented chainring profile for better shifting. 42 x 34 x 24T, 175mm arms.
  • Weight: 950 grams.
  • A variety of materials and finishes are available, from resin-coated steel to polished and anodized alloy to CNC-processed aluminum.
  • All models use industry-standard bolt circles. Three lower-end models use the 110/74mm bolt circle, and the six other models use the 94/58mm bolt circle(HyperDrive-compatible).
  • Chainrings gave a patented system of ramps, pins and tooth profiles to promote smoother, more precise front shifting.
  • Our top two models are made with a one-piece forged crankarm and spider, two aluminum outer chainrings, and anodized finishes. The top of-the -line SR-FC370 also uses high-strength 6061-alminum that is forged and CNC-machined, plus a hard-anodized coating on the rings.
