Kehang Cai (蔡可航) has been competing for 7 years. His best event is the Pyraminx: a personal-best single of 1.71, set at Yancheng Spring Open 2026, puts him in the top 0.69% of the 129,321 people who have ever been ranked in the event, and 76th in China. Until April 2012, no official Pyraminx solve in the world had been that fast. Across 2 competitions since July 2019, he has put 84 official solves on the record across six events. Solve to solve, his 3×3 times vary about 11% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 9.49 in July 2019 to 6.71, a 29% improvement. Kehang has entered two competitions.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
