Captain Fastbastard Mayhem Posted November 11, 2015 Share 20151029_172557.jpgI had the same problem so decided to make my own chainrings with integrated spacers and thread. Works like a bomb. I have since made up a couple more that is being anodized at the moment. Pls pm me should you be interested.You in CNCing & metalwork, I presume?

Attie Lourens Posted November 11, 2015 Share Not sure if I'm allowed to promote these chainrings on the forum pls remove my post if it's not acceptable. The rings are made of 7075-T6 aluminium and is hard anodized. It has a 9.95 mm x 2.7 mm spigot to locate on the spider. The spacer section is 14mm x 5mm which I find to gives the best chainline. Because the ring is threaded your std screws works perfect.

Attie Lourens Posted November 11, 2015 Share I don't suppose you have any oval ones? How many teeth on those rings?Currently only 32T rings.(seems the most popular). 30, 34 and 36 coming very soon. Will definitely look at oval rings if there is a demand for them. Link to comment Share on other sites More sharing options...

Will definitely look at oval rings if there is a demand for them.Gotta get the ovality right, though. It's not just a simple case of having the rings oval in line with the mountings... gonna have to get the amount of angular offset to get the greatest benefit and efficiency. Thermophage 1 Link to comment Share on other sites More sharing options...

Granted I ride flats and maybe that has something to do with it. Link to comment Share on other sites More sharing options...

Forgetting the manufacturers science that says it does for a moment that is .....Problem is this: There is no actual conclusive proof that they do what they are advertised to do. It's inconclusive. Which in my view keeps the burden of proof with the "they do work" school, not the "i'm not convinced" school. Lot's of "could" and "can" used to promote them. I'm more about the "will" whenI'm asked to fork out twice the normal price. So no, I have no hard evidence, but here is some literature on the inconclusive nature of it all (also mostly anecdotal, but that's only fair since the promoters also rely on anecdote): http://www.cyclingweekly.co.uk/news/latest-news/osymetric-chainrings-do-they-work-28044 http://triathlonmagazine.ca/training/bike/pedal-power-do-elliptical-chainrings-really-work/ http://digitalcommons.calpoly.edu/cgi/viewcontent.cgi?article=1107&context=kine_fac http://forum.slowtwitch.com/forum/Slowtwitch_Forums_C1/Triathlon_Forum_F1/Can_We_Test_the_Efficacy_of_Oval_Chainrings_P5365837/ Link to comment Share on other sites More sharing options...
raptor-22 Posted November 12, 2015 Share I'll have to double check, but I did not see one. And even if there is one, I wouldn't want to take it out, don't want to stuff around with the original setup of the bike in that way.I'll check for spacers.On the 1x crank side of things, there are none available in the country as far as I can see. Been on the phone to almost all of the online stores and some LBSs.. Gonna have to stick to my 2x crank setup for now, with 10sp in the back.Thanks for all the positive feedback guys, really appreciate it!Does anyone know the chain line figures for a 2x crank? Is the 1x crank an "in between" measurement?Saw a XT m8000 1x crank at Williams bike shop in Somerset west. Link to comment Share on other sites More sharing options...

I definitely felt a difference when I went over to oval and now I wont go back. Link to comment Share on other sites More sharing options...
