Position One Chain Tensioners

Position One Chain Tensioners are forged 6061-T6 aluminum adjusters for single-speed BMX bikes with horizontal dropouts and 10mm axles. They sit between the rear axle and dropout, stop the wheel pulling forward under hard pedaling and let you fine-tune chain tension. Sold as a pair in blue, red, black or polish.

Features

• Forged aluminum for more density and strength than cast or machined-only parts
• Two fixing holes per tensioner for secure attachment at the dropout
• Threaded adjustment screw with lock nut for precise tension without removing the wheel
• Repeatable wheel position for racers and riders who change gear ratios often
