PDW Twinsies Dual Bottle Cage Holder
Why Is the PDW Twinsies the Best Solution for Two Bottles Up Front?
The PDW Twinsies Dual Bottle Cage Holder is a stem or handlebar-mounted adapter that lets you run two water bottles in front of your bars, a setup that has become increasingly popular on gravel and endurance bikes where frame triangle space is limited or already committed to a frame bag. The adjustable dual-cage platform accepts two standard bottle cages and positions them low and forward for easy on-the-bike access without reaching back to a rear cage mid-ride.
Compatible with most standard handlebar and stem clamp sizes and works with any standard cage mounting pattern. If you're deep into a gravel event or multi-day ride and hydration access matters as much as capacity, the Twinsies is the front-of-bike solution that doesn't require a full bikepacking kit to justify. Works equally well on flat bar bikes and drop bar setups where the stem area accommodates the clamp.
