    Headset Bearing Size? Nottingham Raleigh

    Hi There,

    I was just wondering if anyone knows what size bearings the stock headset of a 1970's Raleigh might use? thanks

    Do you have none? You can take a single bearing to the LBS and they can measure it with the Park ruler and give you a handful of sparkly new balls for a buck or two.

    I'd say it was 5/32.

    '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

    That's the best guess for a loose bearing (or retainer held loose balls) but I also recommend taking the old headset apart as you will need to confirm both the bearing size and the number of balls in each race.

    One additional problem with a Raleigh of that vintage; the fork/headset threading is not the ISO standard used by nearly everyone else so you can't just buy an over-the-counter replacement if the old one is badly pitted. Here is Sheldon Brown's article on Raleigh threading. Scroll down to the section on headsets:

    Also, you might post this guestion in the C&V forum for more detailed info.
