    need big ring for older cranks

    been to several internets retailers, no luck finding a 44T, 5 bolt, 65mm center to center chainring. Anyone got one in their parts box? Setting up the old mtn bike as a hybird.

    I measured the best I can and it looks like my 5 bolt pattern is on a 114mm diameter.

    What you've probably measured is the c-c of adjacent bolts on a 5 bolt ring. Look at this Link from Sheldon Brown for more thorough explanation:

    The 65mm you measured works out to 110mm BCD. Most makers have a 44T ring in 110mm.
