Extruded from 7075 aluminum and precision-machined for minimal weight, they provide adjustable wheel placement with laser-etched position guides. Features dual 10mm mounting holes for compatibility with most BMX frames.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cp\u003e• \u003cstrong\u003e7075-T6 aluminum construction\u003c\/strong\u003e – Higher-strength aluminum alloy compared to standard 6061 provides increased durability in high-load dropout applications while maintaining low weight\u003c\/p\u003e\n\u003cp\u003e• \u003cstrong\u003eCNC-machined from extrusions\u003c\/strong\u003e – Precision machining ensures consistent fit and smooth surfaces for accurate wheel alignment and secure axle retention\u003c\/p\u003e\n\u003cp\u003e• \u003cstrong\u003eLaser-etched position guides\u003c\/strong\u003e – Permanent markings on tensioner body allow repeatable wheel placement for consistent chain tension after wheel removal\u003c\/p\u003e\n\u003cp\u003e• \u003cstrong\u003eDual 10mm mounting holes\u003c\/strong\u003e – Two axle positions provide adjustment range to accommodate different chain lengths and dropout spacing variations\u003c\/p\u003e\n\u003cp\u003e• \u003cstrong\u003eDropout protection\u003c\/strong\u003e – Tensioners distribute axle clamping force across a larger surface area, reducing frame dropout wear from repeated wheel installation\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cp\u003e• \u003cstrong\u003eWeight:\u003c\/strong\u003e 62 g (2.2 oz per pair)\u003cbr\u003e• \u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075-T6 aluminum\u003cbr\u003e• \u003cstrong\u003eAxle compatibility:\u003c\/strong\u003e 10mm\u003cbr\u003e• \u003cstrong\u003eMounting holes:\u003c\/strong\u003e 2 per tensioner (10mm diameter)\u003cbr\u003e• \u003cstrong\u003eFinish:\u003c\/strong\u003e Anodized with laser-etched graphics\u003c\/p\u003e\n\u003ch2\u003eCompatibility and Ideal Use Cases\u003c\/h2\u003e\n\u003cp\u003eDesigned for BMX frames with horizontal or semi-horizontal dropouts using 10mm axles. Works with both cassette and freewheel drivetrains where chain tension adjustment is required. Best suited for single-speed setups where wheel position must be adjusted to maintain proper chain tension. Laser-etched guides help riders achieve consistent wheel alignment, particularly useful when swapping wheels or adjusting gearing. Not compatible with vertical dropouts, thru-axle systems, or frames with integrated chain tensioners. Proper torque is critical—over-tightening can damage both tensioners and frame dropouts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e US orders ship direct from manufacturer and may arrive separately from other items.\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.
