Very quick question

[dannywhiteley]

Are these standard sized chain ring bolts?  I.e. Will they fit a power disc and chainring?  They are labelled as 'double' sized.

[fouronethreeoh!]

Short answer, no.
Double ring bolts are too long and dont clamp up single ring/spider.
They can be "adjusted" to work if you are a bit handy with a file.

[dannywhiteley]

Or a hacksaw?  Could you take a few mm off each one to enable them to tighten up a single disc and ring?

[fouronethreeoh!]

Yes, just shorten the nut part, not the bolt

ill let you know danny ,,i bought some of the bay last night

I suppose you could, if you had lots, pack the bolt head side out with little washers...

ok, it was a silly idea.... but the initial reply is correct, single ring bolts are what you need. Not thateasy toget unless you lbs is into "singlespeed and fixies".  Or old school bmx. When I went into my lbs asking for bolts for a spider, they looked as if I'd walked off the set of Ashes to Ashes, the kids lolled and said BMX haven't come with seperate spiders since they were born, basically......

I left feeling very old indeed.........

p.s this was in the listing i bought off

 These are suitable for double chainrings, single ring and bash ring or the two outer rings of a triple.

Looks like you could either cut down the nut part a few mm, or use standard nuts off a regular set (they arent that visible anyway).  The bolt part would extrude slightly out the back, but nothing really to worry about.

Yep they are a bit too long but very soft alloy so just file em down, shouldn't take a minute.  It would be much more difficult to saw them, got a dremel or a bench grinder?

[dannywhiteley]

Can get my dremmel on the job...

Love a bit of BMX DIY.  Its too easy when things fit first time anyway...

[gossa]

alloy chainring bolts are so soft you could probably chew them down!
