Like you I tried reversing the the 46T chainring so the ramps were on the inside, but I could not get it to work because the chain would hang up on the chainring bolts.
I am wondering how you were able to get it to work. Maybe the Wickwerks chainring is thinner where the bolts hole are, or the bolts are lower profile?
Can you send me a picture of yours?
I am using a Force 22 FD and it still shifts pretty good but the adjustment is really finicky and it tends to throw the chain off the outside.
I am wondering if that is due to the ramps not being on the inside.
Thanks - Joel (we have the same name!)
Joel,
Ill try to post some photos when I get home next week.
I did not think the outer-as-middle ring would work, but it does.
it’s possible the wickwerks ring is thinner? My inner ring is 28, and I think the chain runs below those bolt heads. Chain line matters too. I used the Origin 8 single bolts. They’re steel and may be thinner than alloy? Lastly, are you using 11s? Obviously narrower than the original 9s.
it’s a way out of spec setup but it works great for us. Now that Campy offers a standard chainset as 29/45 I don’t feel as weird.
FYI I’ve gone back to testing the SRAM red etap stuff. It’s growing on me.
I ordered a long cage from Chinook cycles on sale (they’re closing their shop)that will allow more capacity if I want.
