Chainring Problem.

(1/3) > >>

ligbee:
Bought a couple of chainrings (Sugino/SR style) to which I was going to fit a standard Spider. When I tried to bolt the spider onto either of them, it seems that the spider is too small, is there two sizes of spider or is it a power disk fitting only.

Don't remember this problem back in the day.

crusty:
how much to small/big?
are you putting all 5 of the bolts in loose before you tighten any up there are a lot more knowledgable people on here that can help but this is all i can think of for now

ligbee:
You cannot as the pcd of the spider is too small, the radius of the holes could do with being about another 10 mm.

pickle:
i could be wrong but it sounds like you've got a Sugino spider and Takagi chainring?  the Sugino spiders are smaller, thus there rings are bigger and the oposite for Takagi.

hope that makes sense?

ligbee:
That sounds about right.

I'll have to find out which one is which as both chainrings and spiders are copies.

Cheers
