I run XT thumbs (A term used BITD
) upside down (I always have), which I always thought gave me more bar control when shifting in a bumpy section than the normal "above bar" position.
I remember riding a friends bike with the Mavic upside down "thumbs" - the ones with two levers in a kind of "V" shape. I preferred the ergonomics of these, it's just a shame the shifting couldn't match the shimano's
