Front derailleur advice

Hello

Could anyone suggest a bottom pull front derailleur (28.6mm) for a triple 28-38-48 with a view to swapping this for something smaller for touring in hilly areas?

I'm using thumb shifters.

Thanks, Tom

do you need one for flat bar shifters or road drop bar levers?

M571 Deore is what I got years ago for my 48t outer ring triple,
the term 'Trekking' seems applied to the mid sized triples these days.
at least when selling into the EU market.

What thumb shifters are you using? Some are indexed, some aren't. Makes a difference in your derailleur choice.
