Surely they teach you that sh~t, Nick? ???

Symptoms appear within 24 hours, but the first two hours are the most critical. ;)

(a little diving physiology for all you BMXers out there! :daumenhoch:)

I haven't dived for two weeks. :angel:

Go figure! :daumenhoch:

Not the Bends, just too lazy to measure the fookers, although I am now thinking I should have bothered! :coolsmiley:

1983 WIN Stem; same "M" as Sugino (I have tried) but the bolts are a few (maybe 2) mm longer. :daumenhoch:

When I use a set from a Sugino Stem they don't really get enough depth into the base to be safe. :shocked:

HELP! ::)

Post by: steve69 on July 14, 2012, 11:20 PM: I think it's more likely to be M8 which would be for a 6mm allen key (if it were a regular hex bolt it would have a 13mm head)

an M6 would have a 5mm allen key fitting, that sounds a bit small for a stem :-\

Oh yes.

Immediate O2 therapy, attach drip and scoot them the hell out of Dodge whilst maintaining the aircraft as low as possible :daumenhoch:
Not forgetting the dive computer for depth and ascent reference.

Another one saved :LolLolLolLol:
