    Older White crankset, want to change large chainring .. help needed

    I have an older white ind crankset on my Marin MTB. 20-32-42 are the sizes and I am running out of gear on downhills.
    I called white ind up and since it's a sugino made in japan item it might be hard to find.
    I guess I need a 94mm bolt circle BCD ( compact drive ) gear.
    From what White ind told me it might be hard to find them in 46 or 48 teeth.
    They said I should also change the center ring as it's pinned to the outer ring and it might be wise to get both from the same manufacturer.
    The bike is from the 90's.

    Does anyone know of a good online place to order or should I try my LBS ... I don't know the cost of two gears or if it would be better for me to just get a new BB and crankset. The one on there is a square end axle and I wouldn't mind getting rid of that.

    What would be the best thing to do. If I have to spend a few bucks more for a new crank I will. The crank on there has been rock solid so far with periodic tightening after some clicking with the taper. Didn't seem to skip any and after tighening up the crank allens it has been ok I think I read somewhere white made some good cranks but also some they put out were not so good.

    First thing you have to check is do you have clearance to the chain stay for a larger ring.

    Do a Google search using "94mm bcd 46T" and/or "94mm bcd 48T". You'll find more than you can shake a stick at.

    Will I have to add links to the chain?. Looks like I can move the front derailleur up to clear the new ring.
