After going on a ride with a friend who was waxing lyrical about his oval chain ring set up (single ring up front with a chain tensioner just behind the cranks and a rohlof rear hub) I was wondering if it is possible to run one as a SS on horizontal drop outs. I like the clean looks of my SS set up and don't really want a tensioner so was wondering if anyone has any advice, thanks.
You dont need a tensioner to run elliptical rings ss. Have been using them for years on all my single speeds. The trick is to rotate the crank to the 4 o'clock position where the oval is tallest and then set your chain tension as you would normally. As long as you have a nicw chain line it will work perfectly.
This ^^
Works just fine, well it did on my old biopace set up!
I run QRings on my singlespeeds with no issues!
As above, my SS has an EBB rather than track ends, but is quite happy with an oval ring
Like the others I have no problems with an oval ring on my SS with EBB
Same here, it's fine. There will usually be a tiny change in chain length but no more than you get with a regular round chainring as they are rarely perfectly centred.
Coolio. Thanks for the replies. *goes off to have a look at oval chain rings*.
Was discussed including some videos and boring maths a while back

Bottom line - it just works, do it.
