I'm guessing the frame has a 68mm bb shell? Then yes a 68/110 will work, the length of the axle goes with the q factor of the cranks, so low q factor usually requires longer bb axle length, if the chainset manufacturer recommends 110mm then go with that, Spa Cycles has em for £24, buy a couple, I think Shimano have stopped making them.
