I'm very keen on trying out a set for my road bike - guess I would need to go the Rotor route as I would need both rings changed. I currently run 53/39, should I stick to this setup or drop down to 52/39 or even 50/34?

All seems fine on my end. Only 1 each of Wolftooth left in 104BCD.

 

Wolf Direct Mount Oval GXP will also be uploaded during the day.

 

Oh well, guess I missed the Wolftooth, it's out of stock now, and the AB is still giving the same error, I assume that one also got snatched up. Just left the office for 15 mins...

I'm also keen, Let me know if you change over and how it goes. You running the new dura-ace 4 arm spider on your spez if I remember correctly?

For those interested in the O'Hara study on Elliptical Chainrings - read the study here:

Out of interest - Christine's idea was to DISPROVE ROTOR's claims. She now works for them...

Unfortunately no, as these rings have a narrow wide tooth profile designed to have excellent chain retention. In other words, the chain does not like to climb off the chainring which is ideal for 1x drivetrains.

 

However Rotor does make 2x10 oval chainrings but I cannot vouch for them as I don't know of anyone who uses them. But their pricetag can make many people blind by just looking at it...

I have Rotor 2X10.  Still crying, didnt do proper research, paid the price....pun intended.

In what way - please elaborate! :thumbup:

Would also be interested to know, I ride with those and no I can't say it has improved anything by x percent but it hasn't done me any harm ....
