Hello everyone,

First time posting here so hopefully someone can help.

I have a Tern Verge P18 which is about 5 years old now & after maybe 10k miles the original drivetrain is on its last legs.

The front current setup is a 55/44 on the front and 11-32 on the back. The front chainrings are proving very difficult to find a replacement for in the same specification, 55/44 seemingly being a somewhat unusual setup, so I was wondering if anyone knows if there's a particular reason for having these sizes of chainring on the front. For example it seems worlds apart from the 50/34 on my regular road bike.

Obviously the folding bike is a very different beast (11.5kg, 20 inch wheels, probably a different crank length) so I guess there is a good reason to have different gears to a regular road bike, but in the absence of a direct replacement I was wondering if anyone on here has a similar bike to mine & if so what gears they have, or failing that any ideas as to what else might work if I can't have exactly the same setup as I currently have.

Hopefully I've explained this reasonably well - any help / advice / product recommendations much appreciated.
