DB mentioned above all info.
To answer
your question Shyam, I have a high quality steel roadbike which is just
around 10kg (No aero, nothing). But I have installed a ridiculously low
gearing.
Double chainrings: 38-26 or 24 and Cassette:
13-30 I think. And I have climbed some really steep climbs, no problem
with this gearing.
Actually it was very easy ride from Shimoga to Agumbe.
If you want to know Bike and ride report starting from Shimoga, it is here:
