I need to replace the front derailleur on my tadpole trike. Unfortunately, I cannot find a brand name or other numbers anywhere on the derailleur, so I cannot just replace it with an identical product. When looking at new items, they have many numbers and measurements which I do not understand, so I do not know whether I will be buying one that fits.
- It has three gears.
- The back derailleur is an 8-gear Shimano Deore.
- I use MicroSHIFT shifters.
- The other bike parts appear to be in metric.
- The post that the derailleur clamps onto measures 28 mm in diameter.
What details do I need to look for to know that a replacement will be the right size for this bike?
