You can buy a Loctite product that is used to make threads.

loctite form a thread

read up on this stuff and it seems to be the real deal and is used on guns so must be reliable i would assume

A decent quality threadless should be fine IMO/E.

i doubt very much you would get a helicoil in that size and with a left hand thread :!: :shock: :?:

yes you can > http://www.ebay.co.uk/itm/Bottom-Bracke ... 3cb2896bee

i've had a frame helicoiled by this guy (both sides) way back last year and it's still solid


it's a bit pricey al but well worth the cash




some memory on yi kaiser

I'm only going to ask the following as I'm on such a tight budget:

As the BB cups have a 2mm spacer on each side (between themselves and the frame's BB shell) could I - theoretically and with some knowledge of the detrimental effect this will have on my chainline - remove the 2mm spacer from the driveside fitting procedure to allow RH cup to bite into an extra 2mm of remaining thread?

Just a thought like... must be worth a try if the frame is already damaged, and if I at least get remaining threads chased, I will still have some thread contact!?

*awaits barrage of disapproval*

Technically yes (if it's anything like HTII) and you put the chainline back to 47.5 and reduce the q-factor-thing. You may need to modify the cups/bit between them, splines, depending on how far you go.
I've seen an article on it, I'm sure it was the MAG21's on a kids bike person but cannot find my link.
