New chain gettin put in the nc30 this week bought a standard kit but thinking about changing sprockets either the 14t front or 42t rear. What's best??

Don't want too much bottom end and no top end as it's not bad as it is STD.

Cheers

Road bike by the way

Both pretty much the same in terms of performance do doesn't matter which one you go for.

Ok mate cheers,

Will the chain be long enough to change from 40t to 42t rear without worry?
