My first tandem from Orbit was not,hence the work around required a half link in the connecting chain.

This is my first non derailleur bike and its a bit of a learning curve on the new bits. At least I’ve got a working bike again.
It has a large tube size.
Australian Cycling Forums Skip to content. Is this the eccentric bottom bracket used on a Cannondale trail SS 29er? So I loosened the key a bit more had another go, really pushed hard. Once the chain is adjusted to correct tension,tighten the wedges but don’t overtighten the wedge bolt,5Nm is enough ie;two fingers bogtom pressure on a standard sized allen key or you run the risk of distorting the EBB housing in the frame.
This eccentric is 68mm long and It is slightly smaller in diameter than the “Eccentric Bottom Bracket Insert Taiwanese” also sold on this site which was a fraction too wide for my bike. Or the other which is what I did cannondale to change both drive chain rings by one tooth down 30 You may not post new threads.
The allen key goes into the complete end of the cylinder and as it’s tightened draws the wedge bgacket creating a friction fit in the bottom bracket. I gave the head of the allen key a couple of taps with a tack hammer but I can’t seem to budge anything.
The other screw I’m assuming is a locking screw??
Cannondale eccentric bottom bracket adjustment???
Now’s the time to strip it,clean,regrease and reassemble the Eccentric BB,so you know it’s done correctly for next time. Before I break something I thought I’d better check my understanding of the setup; to me it looks like the eccentric is basically a cylinder with a diagonal slice off one side.
I don’t want to hit the allen key to unbind the wedge for fear of knackering eccentrci threads but Ccannondale can’t think of any other way to get it out. SJS Cycles part number: These are hard to find and it did the job. I used grease when installing it and so far it’s silent and squeak free.
Off to the garage now to ferret for appropriate long allen key. How do you adjust an eccentric bottom bracket?
Cannondale eccentric bottom bracket adjustment??? – Singletrack Magazine
Took it out still didnt budge so just put it all back together. Often the latter is a peg spanner fitting but maybe the charge uses a different system to that. Can anyone advise how I can adjust this please.
boytom Nevermind, I am going to follow some instruction I have been given by a fellow owner. IIRC it is usually the case that one or both wedges are held captive to the assy by the overhanging heads of the button-headed screws; it idea is that once brackeg wedge comes loose the other can still be released OK. Once re-greased and correctly adjusted, insert M5 bolt from the correct side and tighten with 4mm Hex key as per instructions.

Plenty of grease around the edges of it from when it was put together so don’t think t would be seized, any ideas for future reference? Can’t find any more info other than that document.
