Does anyone here run oval chainrings on an electronic shifting setup? How often do you have shifting problems and/or dropped chains?
I recently installed Rotor Q rings on my bike and despite getting everything dialed in, I still have problems shifting up from the 34 ring to the 50 ring. I have to find a sweet spot to get the chain to shift into the big ring, otherwise it’ll make a horrible crunching sound and then drop back onto the small ring. I’ve had 1 instance where the chain dropped off the big ring and got stuck between the BB and little ring, scared me to death because I thought I destroyed the bike frame.
A mechanic told me that oval rings and electronic shifting don’t work well together. He said that with mechanical shifting, you can finesse the derailleur while electronic shifting is basically brute force shifting. Brute force works well when the chainring is round but can cause issues with oval chainrings; apparently he’s seen cases where teeth have been broken off oval chainrings with electronic shifting.
Does anyone have any experience with oval chainrings and electronic shifting? Is difficult shifting just the norm with oval chainrings?
