The dual mounting holes provide fine adjustment range to dial in optimal chain slack, protecting frame dropouts from stress while keeping your rear wheel securely positioned. Essential for bikes without internal gearing or derailleur systems that require manual chain tension management.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual mounting holes\u003c\/strong\u003e – Two adjustment positions on each tensioner provide a wide range of fine-tuning capability to accommodate different chain lengths and frame geometries\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorizontal dropout compatibility\u003c\/strong\u003e – Designed for frames with horizontal or semi-horizontal rear dropouts common to BMX, fixie, and single-speed bikes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDropout protection\u003c\/strong\u003e – Proper chain tension reduces stress and movement at the dropout, extending frame life and preventing potential cracking or deformation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel retention\u003c\/strong\u003e – Maintains rear wheel axle position in the dropout, preventing accidental wheel slip during hard braking or acceleration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable tensioning\u003c\/strong\u003e – Allows you to dial in the precise amount of chain slack needed for your specific setup without over-tensioning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal compatibility\u003c\/strong\u003e – Works with standard 10mm axles and most horizontal dropout frame designs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle compatibility:\u003c\/strong\u003e 10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Dropout-mounted with dual adjustment holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Chain tension adjuster\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel (standard construction)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e Sold as pair (left and right)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility \u0026amp; Ideal Use Cases\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBox Two chain tensioners fit any BMX or single-speed bike with 10mm rear axles and horizontal or semi-horizontal dropouts. They're essential for fixed-gear BMX setups, track bikes, and any frame without internal gearing where manual chain tension adjustment is required. Proper tensioning prevents chain slippage during hard acceleration, protects frame dropouts from stress concentrations, and ensures predictable rear wheel positioning. Not necessary for frames with vertical dropouts or internal chain tensioning systems. Compatible with all standard 10mm BMX rear hubs and axles.\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.
