For this reason, we have chosen to use the gold standard of hub design, the star ratchet. On our AR1 hubs, we offer both 36T and 54T options depending on how much engagement you prefer.36T ratchets are recommended for most users due to lower rolling resistance and improved longevity. 54T ratchets are recommended for those who require higher engagement, for example in crit racing.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"mso-spacerun: 'yes'; font-family: Calibri; mso-fareast-font-family: 等线; mso-bidi-font-family: 'Times New Roman';\"\u003eThe AR1's ratchet hub shells and axles have been machined to 0.005mm tolerances, lowering rolling resistance and improving bearing longevity.
