Re:
Done this job on two Konas, removing the original bottom brackets.
'96 LavaDome with Shimano STX cranks was originally Shimano BB-LP25 110mm, i replaced it with better/later version BB-UN54 110mm.
'95 CinderCone with Sugino Impel 500 cranks was originally KSS TLS 110mm, replaced it with upgraded Shimano BB-UN74 110mm.
All four BBs were necessarily 68 / BC1.37x24.
Original crank and chainring-to-frame clearances were achieved in both cases.
