While waiting on news about the fork I started double checking my gearing. What I found was using a 41/53 crankset and a 14-28 freewheel would have me virtually duplicating several gears, and was pushing the capacity of the derailleur. So I decided to swap the 53t chainring for a 50t ring. Yes, I’ll lose a bit of top end, but I suspect I no longer have a top end.






I couldn’t find a Campagnolo chainring, so a Sakae will have to suffice until I do. However, the Sakae doesn’t have a peg, so I popped one off a well-worn Campagnolo ring. The pin on the peg is 3mm (.118”) and I drilled the hole with a #32 bit (.116”) to give it a slight press fit. I tapped the peg in with a bit of red Loctite to help hold it in place, then staked the back side of the peg. At least the Sakae resembles a Super Record chainring.
