Force D2 DUB Wide Road Chainset With Power Meter Spindle - 43/30T Direct Mount Chainrings - BB Not Included (2023)

Our 43/30T chainring combo combined with a wide chainline increases tire clearance while providing ideal gearing for venturing off-road. But gravel riders need power measurement too, so we’ve elegantly integrated Quarq technology into the DUB spindle, stealthily gathering the data you need to progress.

Features

• DUB-PWR spindle-based unit measures left side power to calculate total watts
• Proven Quarq reliability and accuracy
• Long battery life (400+ hours) to power a season of rides
• User replaceable AAA lithium battery
• DUB bottom bracket adds durability and simplicity
• Waterproof (IPX7 waterproof to 1 meter for 30 mins)
• Lightweight (less than 40g heavier than standard crankset)
• Wide chainline crankset for bikes with up to 700x45c or 27.5x2.1” tire widths (43/30T chainrings only)
