I have been chewing chains out too quick on the Gefsco lately and the Campy chainring came up as the main culprit. Getting worn and didn’t help that it is 3/32.
I wanted to retain the look and the new job came up better than the original - cleaner finish and way better drilling geometry! Check the pic - try to overlook my “almost” polish job and photography!
Their chainrings appear to be SS-specific “Because our chainrings are not designed for front gear changes our tooth profile is thicker we have less of a chamfer (less of the corner is machined away.)”
Do they do a derailleur-specific tooth profile as well or is the difference trivial on a geared chainset? I want a couple of unusual chainrings and CU’s ones are cheaper, easier to obtain and sound like a better option.
I listed everything I wanted with Johnny by an exchange of emails and he sent it up, easy as that.
Suggest you each do the same, you will find him realy helpful, have at it!
I am away in Victoria freezing my nuts off and have only ridden it briefly, initial impressions are very favourable, I am pretty fussy about drivetrain noise and feel. The Phil cog is way noisier. Still have to pedal up hills, tho … and down, now that I think of it!!
mine is virtually silent as well. big ups to CU
Once we worked out what I wanted, Johnny cut it and express posted it the same day. I got it the next day. I couldn’t ask for better customer service
He’s not doing shifting rings at the moment as they take fair bit of R&D to get the shifting ramps/pins right. And as you can see from John’s work, he’s not into doing anything halfarsed.
