They are the world's lightest UCI approved road\/gravel wheels. One of the primary ways this was achieved was with a cutting edge carbon layup. Our lightweight rims are essentially unmatched when it comes to low inertia, significantly improving acceleration. \u003cmeta charset=\"utf-8\"\u003eThey currently represent the lightest production wheels of their rim depth.

As opposed to most carbon spokes, they offer a more comfortable, compliant ride, that is more akin to steel spokes. 4th generation spokes achieve such a low weight due to titanium spoke heads and threads as well as different profile. Note that 4th generation carbon spokes are 13% more compliant than 1st, 2nd, and 3rd generation spokes, giving them a ride feel more closely resembling steel spokes.\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';\"\u003eOne thing that not well-known is that not all replaceable carbon spokes are made the same.
