Title: Theres a spider in my bathroom I need removing!
Post by: Juju on March 28, 2009, 05:51 PM: And more accurately, its attached to my sugino cromo 1pc.

Its a Odessey Black Widow chainring, (what ever that is - a bit new school for me) and itseems to be held on to the crank by a circular (ie non nut shaped) nut, with three tabs cut out of the circular nut (Am I explaining this well?)

How do I remove it? Is there some special 3 slotted spanner I need? Theres a cute old school sugino spider just waiting to go in instead.....

Post by: lazychubs on March 28, 2009, 05:54 PM: use a nice blunt object and hammer to undo the nut
as it would be quite hard to find the right tool

Post by: Juju on April 14, 2009, 08:11 PM: Ok, can someone please confirm to me that I have been a total prat..

If I hold the 1pc crank, with its NON driveside arm towards me, (facing down), the bearing race screws on counterclockwise. Therefore, it screws off clockwise.

From this, I deduced that the nut holding on the chainring, given that it cannot (from the look of it) come off the crank over the slightly fatter shoulder of the drive side, must logically come off on the non drive side. For it to to do so, I assumed the thread must mean it too must screw ON the same way as the non drive side, and therefore unscrew clockwise.

So after 20 mins banking it with a hammer and screwdriver, I managed to move the chainring nut about 5mm, and that took me 20 mins.

So have I actually just tightened it to buggery, and failed to see something terribly elementary, and should the drive side nit holding the chainring actually remove itself counterclockwise, defeating my logic?

Or should I just piss off down the bike shop and hand it over to some nice people who arn't idiots?

Post by: BrianP on April 14, 2009, 08:16 PM: pretty sure the nut holding on the chainring is a right hand thread dude, like a regular nut...

it's only the non-drive side bearing cone nut and locknut which are a left hand thread.

Post by: Juju on April 14, 2009, 08:23 PM: So, to use northern terminology you think I've been a right fookin twat, and simply spent 20 mins tightening up all already bloody tight nut?

/scream

I just assumed I'd not been putting enough effort into the hammer!

Post by: BrianP on April 14, 2009, 08:31 PM: i think so bud, sorry. but if it makes you feel any better, i broke a spanner trying to remove the non drive side pedal on my first bmx before realising it was a left hand thread...

ps this was in my bath a while back:
