Does anyone have any experience with these chainrings?

For those interested...the BOR Germany rings (50/36) are 19 grams lighter at 135g than Praxis Cover (52/36). Hopefully they shift just as well as the Praxis...

I have a set of 53/39 on my TT bike and they work great. No issues, shifting up and down is flawless on my set up with Campagnolo TT 11 Speed shifters. Stiff and they look great. Got them at a great deal to replace some CT2 and I would say slightly better than the later.

Cheers,

Thanks for the feedback re: shift quality and stiffness. I won't be able to test mine for at least another 2-3 weeks. Using them with Campy 11 as well.

Any more reviews on these rings? I'm interested in running them Sram eTap in 53/39t on Quarq Dzero red cranks..

I'm very happy with mine, I have a 50t and Tune 34t no issues really (after 2000k), I use it with 11 speed force. They stay black for a much longer time than stronglight ct2.

When I look at Tune chainrings the only difference i see is where the chainlifters are placed.

Had no problems at all so far.

34t weighed 35g
38t weighed 41g

I think both were slightly heavier than advertised, but not much.

I'm looking at using these again on a build for this year.

Do you think there is any performance difference from standard rings or Praxis (which people seem to like)?

i had them but switched to Praxis on my M3 cranks. Before BOR i used standard Super Record and notice a big difference in shifting (inner to big ring), maybe they need a 'surgical adjustment' FD.
My 53t BOR weight 99,95g (10g over the attached on ring)
