Stay hydrated with the patented SpeedfilTM F2 system. The F2 works with any Specialized thread compatible water bottle in both 21 and 24 ounce sizes. The F2 model enjoys many of the same benefits as our standard Speedfil. The dual splash resistant design allows the rider to refill the system on the fly. Just prime the Speedfil system once and you have access to your hydration immediately. The bite valve and tubing keep fluid on demand without sucking up air for each drink.
The Speedfil Off-Road Bundle includes the F2 and our exclusive micro-retractor. This military grade retractor allows the rider to pull the drink tube up to 24 inches from the handlebars, drink, and then release. With up to 6 oz. of force, the retractor snaps back inside the keeper with no hesitation.
