3 speed derailers with triples. Derailer is positioned where it should be with about 3mm clearance between the outer teeth and the bottom of the derialer.
This one has a Microshift R8 front derialer with a 48 tooth outer. You can see there is plenty of room between the frame and derialer.
This one is a 46 tooth outer with a Shimano front derailer. I think it’s a Sora triple. Inner ring is a 20 tooth. You can see that there is a lot of room between the bottom of the derailer and the frame. I could easily use a 44 without issue.
Both of these derialers were are used and just pulled from the box o’ parts at my co-op (the Cannondale picture was actually taken at the co-op). I didn’t measure or even check the range of either before installing. I just installed and tuned them. They work perfectly.
