Specialized class the front mech on my bike as:
Shimano M581 LX, 34.9mm clamp, bottom swing, dual pull
It looks like:
Surely what I actually have is a Shimano M580 LX, 34.9mm clamp top swing, dual pull?

yep looks like the FD-M580"Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Thats the third difference from spec on my Stumpjumper:
Different inner tubes
Different sized rotors
And now different front mech!
Is there any advantage to one type of mech or other?0 -
I think bottom swing are less prone to seizing when full of crap but I don't think it makes a lot of difference (I have both types on different bikes). If I had a choice I'd go for a bottom swing unit, think they look better, particularly the new XT.
Didn't have a choice with my hard tail frame, there's a bottle mount in exactly the wrong place which fouls the clamp on a bottom swing mech so I had to go top swing (I think this is the main reason there are two/three types if you include the e-type mech, so that they can accomodate all frame types).It's easier to ask for forgiveness than for permission.
I've bought a new bike....ouch - result
Can I buy a new bike?...No - no result0
