I know you can replace the bearings in HT2 cups but am I right in saying it's a thinner bearing than the easily found jobby?

snaps - how easy are they to change? - just realised my htII is shot, so may be interested if i don't need to buy any tools.

Aren't they 7mm wide? I tried some 6805s in my bearing cups a while ago and they were a little too wide and the cranks didn't fit properly - I think the bearings that came out were 5.5mm or something.
Have there been two different types of cup?

I found I could fit the 6805 bearing fitted but they need top hats, and the orignal's wouldn't fit, due to the 7mm wide issue.
Anyone get to the bottom of this?

(I was told about a shop that might be able to offer new tophats, but have been distracted of late)

Easy to change, drift out press in - 5 minute job.
Someone else mentioned early Shimano did have narrower bearings but replaced them with the wider ones & trimed the plastic tube by a couple of mm.

The tube inside the frame or the tophat? I can't see what trimming the tube would achieve. The problem I had was with the tophats not fitting properly - I got them on but the crank was a tight fit and obviously not right at all.
I went and bought a new BB but still have the old one and would like to use it if poss on another frame.

I'm not sure as I've fitted new bearings to about a dozen BB's but not come across any with the narrower bearings.

All bearings sold but I've had numerous enquiries so will be ordering another batch of 40 to get them at this price - if you want some my emails in my profile.
