If they aren’t, you get creaks, loose rings, and eventually chewed splines on expensive motors.\nBiggest customer mistake: trying to remove these lockrings with punches, hammers, or generic spanners. That destroys lockrings fast.\nSecond mistake: reinstalling without a torque wrench. Hand-tight isn’t enough on STEPS.\nAluminum body is fine because it’s meant to be used with proper torque — not impact tools.\nWho this is really for: shops or serious home mechanics servicing Shimano mid-drive e-bikes.\nWho should avoid: anyone without a torque wrench or anyone not working on STEPS systems.\nTypical service scenario: chainring replacement, deep drivetrain cleaning, or motor service.\nMechanic advice: always clean threads, apply light grease, torque to Shimano spec, and re-check after first ride. These motors don’t tolerate sloppy installs.\n\u003c\/div\u003e","brand":"Union","offers":[{"title":"Default Title","offer_id":53066471801146,"sku":"UNIOR-STEPS-LOCKRING","price":50.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5735\/8394\/files\/1724_SSL_png.webp?v=1771693612","url":"https:\/\/gograva.com\/products\/shimano-steps-chainring-lockring-tool","provider":"Grava Adventure Corporation","version":"1.0","type":"link"}
