Designed for threaded-lock mounting on compatible frame hooks, it gives riders a reliable way to refine their folding bike's gear changing and chain management system. As a dedicated chain tensioner, its primary job is to keep the chain properly guided and tensioned during every biking Whether you are cruising through city streets, unfolding your bike for a short trip, or tackling rolling neighborhood roads, it works with compatible rear derailleurs to deliver smoother, more consistent gear changing you can count on. Crafted from aluminum alloy with a lightweight open-frame arm, this rear derailleur tensioner keeps overall weight reduction to just 105 g without sacrificing durability. The 8-tooth nylon guide wheel runs quietly and reduces friction, making it well suited for regular folding-bike maintenance and long-term everyday use. Installation is straightforward thanks to the threaded mounting axle and sized mounting bracket interface. The groove measures 26.3 mm wide and 20 mm high, with a 17.8 mm circular hole, so this folding bike chain tensioner seats securely on compatible portable foldable bike folding bike for a stable, rattle fit. Its compact dimensions make it ideal for space-conscious folding bike builds. The arm stretches 114 mm long, the guide wheel has a 32.5 mm diameter, and the circular chain-guiding wheel assembly offers 12 mm of width with 38 units.5 mm overall mounting depth. Together, these proportions create a sleek, functional tensioner that supports clean drivetrain performance on folding bikes.\n\nOption: Black","category":{"slug":"cycling-garage","label":"Garage & Ride","google_path":"Vehicles & Parts > Vehicle Parts & Accessories > Motor Vehicle Parts"},"product_category":"Vehicles & Parts > Vehicle Parts & Accessories > Motor Vehicle Parts","brand":"SuntekStore","condition":"new","price":"38.99 USD","price_amount":"38.99","currency":"USD","price_valid_until":"2026-10-31","tax":"US sales tax calculated at checkout (prices exclude tax)","availability":"in_stock","inventory_quantity":20,"max_quantity_per_order":10,"shipping":"US:ALL:Standard Shipping:12-22:0.00 USD","delivery_days":{"min":12,"max":22,"handling_business_days_max":4},"ships_to":["US"],"shipping_cost":"0.00 USD","return_window_days":30,"package_dimensions_cm":[21.64,17.75,6.0],"weight_g":120.0,"material":"Aluminum Alloy, Nylon","package_includes":null,"image_link":"https://suntekstore-img.sfo3.digitaloceanspaces.com/p/d7/d754494d815a9395088550c3da846802d364dceb.jpg","additional_image_link":["https://suntekstore-img.sfo3.digitaloceanspaces.com/p/65/65b38dccbd79e3b6afcf6f838697b52dd8063e0f.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/3d/3d0d1eefc40859069eb946773dcdcd5e673b1dd5.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/1d/1d41e7645d1cc6515082781075c28b45c3d0a3df.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/cb/cb1fd7b173a41c47550c034303b99f9ad966ae32.jpg"],"link":"https://suntekstore.com/p/DCD-10001600554/","markdown_url":"https://suntekstore.com/p/DCD-10001600554.md","json_url":"https://suntekstore.com/products/DCD-10001600554.json","buy_url":"https://suntekstore.com/buy/DCD-10001600554?qty=1","prop65_warning":null}
