However, the shoulder of the fork may be alloy ... and, the steerer may be alloy OR steel (if threaded) ... If the fork weighs about 400-to-450 grams, then it is probably carbon fiber. |

If you are worried that the fork may be metal [there is NOTHING wrong with a good steel fork, BTW, other than the weight penalty of about a lb.], then (while holding one of the fork's legs) pour some HOT (~120º) or ICE water onto the leg a few inches from your hand ... and, assess the temperature transfer ... If there is an obvious temperature transfer, then the fork is metal. If there isn't a signicant (any) temperature transfer, then the fork is carbon fiber (unless you/someone "carved" it out of wood/whatever!, painted it, etc.). |
