Hello,
As we all know , there are a huge variety of bikes out there with different geometry to fit our riding needs,
Can anyone please enlighten me on how does various tweaks (BB height , top tube chainstay etc) aids us in different moves?

from my experience,
I can sidehop higher with my Modulo Polo(Higher bb rise)
But i feel much more balanced on my Monty 221PR

So please shed some light on this trivial issue ya?


thanks

Lower bb= lower center of gravity point on both wheels, easier to balance.

Higher bb= higher on the bike , making the object that you are going up to lower relitave to your feet, maybe?
Also with higher bb, more stable on rear wheel, also in conjuction with shorter chainstays.

you don't measure top tube length like on most bikes with a trials bike, you measure wheelbase length.
