Ball bearing size
Fruity P
Posts: 3
Good Evening One and all.
The ball bearings in my Maddux RS 3.0 (Cannondale Synapse) are making a grinding sound, i've checked them out and most are quite pitted
, i don't really want to measure from these, so, does anyone know what size ball bearings i would need to replace these ones ??.
Cheers in advance

When buy balls buy grade 10 chrome. Grade 25 is fine but anything less wear you hub more qucikly. Stainless balls pit faster than chrome balls too but chrome balls need a very good grease (rock n roll super web for example) and lashing of it otherwise if water gets they will rust and that is not good.
Most balls you buy from bike shops are grade 100 at best, 300 commonly or 1000 if you are unlikey. Why becuase that is what the distributors sell unless your LBS stock Shimano balls (grade 25 stainless) or Wheels manufacturing not too sure what these are but they good. Still grade 10 chrome is best and you can buy these from your local bearing supplier. Buy a bag of 100 and you will have your servicing covered for quite some time.
Your ball bearing size may be smaller on the front compared to the rear. Rear hubs that use loose or caged ball bearing use 1/4" balls. Some cup and cone front hubs use 1/4" balls others use 3/16". The most valuable tools you can buy if you are doing your own maintenance is a vernier caliper it means you can measure with ease and accurately.http://www.thecycleclinic.co.uk -wheel building and other stuff.0 -

I'd also love a recommendation for a decent vernier caliper or e equivalent as there are loads out there ranging from v cheap to crazy expensive. Some get very mixed reviews so it's hard to know what to get. Is it possible to get a decent one for < £15 or so?0 -
Yes, I have one of those £6 ones off ebay and it works fine.
For measuring ball bearings though I rather like my Park spoke ruler:

Have a look on here...

Mitutoyo and Moore & Wright are both decent to use and should last.
Have a chase around on Google and the Bay.0 -
I have one that looks like the stainless version here: http://www.ebay.co.uk/itm/ELECTRONIC-DI ... 5402bb5f91
(other sellers may be even cheaper)
It's worked flawlessly for over a year, and is certainly accurate (and precise) enough for bike purposes.0 -
In case you haven't ordered one yet, Aldi have them on sale, with 3 year warranty...

brand name for loose ball bearings is irrelevent the grade define's the dimensional tollerances and the chrome define's the chromium content. I fact the grade to a certain extent define the alloying consitents of the steel as well.http://www.thecycleclinic.co.uk -wheel building and other stuff.0
