Installed between the rear axle and dropout, these tensioners prevent rear wheel slippage under pedaling loads while providing fine adjustment for proper chain tension. Sold as a pair for left and right sides.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eForged 6061-T6 aluminum\u003c\/strong\u003e – Forging process increases material density and strength compared to cast or machined-only construction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual fixing holes\u003c\/strong\u003e – Two holes per tensioner allow secure bolt attachment to the frame dropout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle-screw adjustment\u003c\/strong\u003e – Threaded adjustment screw with lock nut enables precise chain tension tuning without removing the wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10mm axle compatibility\u003c\/strong\u003e – Designed specifically for standard 10mm BMX rear axles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnti-slip function\u003c\/strong\u003e – Prevents rear wheel from pulling forward in the dropouts during hard acceleration or pedaling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061-T6 aluminum, forged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle compatibility:\u003c\/strong\u003e 10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixing holes:\u003c\/strong\u003e 2 per side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment method:\u003c\/strong\u003e Single screw with lock nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 64g per pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame compatibility:\u003c\/strong\u003e Horizontal dropouts (classic open-end dropouts)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold as:\u003c\/strong\u003e Pair (left and right)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility and Ideal Use Cases\u003c\/h2\u003e\n\u003cp\u003eThese tensioners fit BMX frames with horizontal or rear-facing open dropouts and 10mm rear axle spacing—the standard configuration for most single-speed BMX bikes. Not compatible with vertical dropouts, thru-axle systems, or frames with integrated chain tensioners. Verify your frame has open horizontal dropouts before ordering.\u003c\/p\u003e\n\u003cp\u003eBest suited for single-speed BMX riders (racing, park, street, dirt) who experience rear wheel slippage during hard pedaling or want precise chain tension control. Chain tensioners are particularly useful on frames with long horizontal dropout slots where wheel position can shift, or for riders who frequently change gear ratios and need repeatable wheel positioning. The dual fixing holes and adjustment screw allow you to set proper chain tension (typically 1\/2\" vertical play mid-span) and lock the wheel in position to prevent movement. Ideal for racing applications where consistent chain tension ensures efficient power transfer and prevents dropped chains. Also useful for riders running tight chain clearances who need precise adjustment. Not necessary on frames with vertical dropouts or integrated tensioner systems, where the dropout design already prevents wheel movement.\u003c\/p\u003e \u003cdiv\u003e\u003cp.\u003e\u003ci\u003e\u003cu\u003e\u003cfont size=\"2\"\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/p.\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e**Due to unique nature of this item, ALL sales of this product are FINAL.
