Hi all. Searched to no avail. I've just converted my hardtail to singlespeed using the Forward Components EBB. I think I have the tension set pretty well, but on my first real ride I kept dropping the chain. It generally happened when climbing while hitting a bump or drop.

I maxed out the tension with temporary improvement but then the problem suddenly got quite bad and I had to bail. The chain is pretty well tight witout obvious loose or tight spots. I was able to get it back on without detensioning each time.

Any ideas on the issue? Chainline? The chainring is on the outermost position and the cog is most of the way outboard. Looks pretty straight. I'm running 44/25, with a new LX crank/outer ring, and a Shimano cassette cog with spacers on a Deore freehub. Something to do with the sizeable cog and chainring? Clumsy riding (I think not!)?

Thanks guys.
