SIMS CRANK ARM CAPS

The Sims caps bear a resemblance to the Grafton caps, and at one time they were near impossible to tell apart. Only recently Mr. Sim has changed the method of removal from a straight slot to a 5mm hex fitting.

These lightweight caps are machined from aluminum rod with a tapered outer edge that tightly seals the crank arm cap hole. The caps have 22mm by 1mm threads to fit all the cranks requiring dust caps reviewed in this article. The pair is lightest at just 3.5 grams and they come anodized in Blue, Black, Lavender or Silver.
