Missing Balls! M730 XT headset bearing help needed!

[benbonty]

Hello all, I have a nice 1 1/4 loose ball M730 XT headset ready to fit to my recently acquired TITAN Titanium frame, but it is missing a few balls! Does anyone have a link to those superb shimano technical docs, or any info on the size would be great! Many thanks in advance.

I tried some bearing specialists with no luck as they are all sealed now!!!! I did however find loose bearings in an oldie world bike shop in the next village. I think they were just under 4mm, so imperial size?!? 80p for 50.! Bargain if you can't get any pm me and I'll bung some in the post?!?

Thanks mate, was this for a 1 1/4 headset? I'm considering buying a vernier just to make sure i get the size right!

completely off the top of my head here, so forgive any mistakes, but I'm pretty sure the 1-1/4" XT takes bearings that are 5/32 in size and (also from memory) this equates to 5.4mm???

Like I say it's all off the top of my head... so could be wrong..

Mine is off an Alpinestars Cro-Mega 1-1/4", runs fine! I'll watch this thread, if you can't get hold of any, and get desperate, let me know?

Thanks very much chaps, 5/32 bearings are cheap and plentiful on ebay so I've ordered a few in the hope that you're right! Thanks again!

I am not an oldie worls bike shop I keep a large stock of loose balls in all sizes. Make sure the bearings you have ordered are grade 25 stainless.

That's Shimano probably used in a XT headset.

I do have the instructions scanned and ready to go up (not sure I scanned it though) can pop them up later.

but convert to fractions of an inch and a standard size and you're there/=.

Which is a bugger as I'm sure it was 1/4" for the M736 (the bearing sizes varied with headset size.)

Saying that the M730 is a different series to the M735 (1"), 736 (1-1/8"), 737 (1-1/4") series.
