Dumbass... I didn't say I could only tell if the saddle height was off
by 2cm. I said within a cm or two I can tell you how much to move it
to get it right without measuring first. Beyond a couple of cm out of
norm it's so far off that I can't tell how much to adjust without
measuring first. A couple of mm is within the 2cm limit, and yes... I
can tell if I need to move the seatpost by only 1 or 2 mm. Big
difference in that and agreeing with your dumb ass.

you're not alone, but kunich could never respect that - he's only here
to **** and moan. and in that respect, this forum, unfortunately, feeds
his trolling only too well.

what a typically dumbass kunich comment! within 1mm on a 1mm electical
component is a chuffing big deal. and most experienced mechanics can
tell the difference between a 11mm and 12mm fastener on sight. but
kunich won't qualify a statement so it makes sense, only so that he can
stir the pot.

as for mentioning ethnicity, it's utterly freakin' irrelevant kunich.
goddamned troll.

He wouldn't have to do that if you'd stop asking, "does this saddle
height make my ass look fat?"

When you ride up to people and ask if they've
got an allen wrench, that's the tipoff.

Hey, can you hold my post while I adjust this nut?

I thought the original question was whether an increase in cranklenght
from 172.5 to 175 would change the biomechanics to increase power and or
duration. Along the line this is changed to be equivalent to 'can you
measure cranklenght by pedalling half a revolution' and topped up with
the ridiculus statement that the human body cannot detect small variations.

And before anyone asks I'm not a succesfull coach, I but know a few who
are (who willl freely admit to zero knowledge about biomechanics ;) )

I'm guessing you're not a 'South Park' fan, or perhaps you'd have
caught the reference to Cartman's constant retort to any time the
other kids call him fat.

Parker and Stone did not make it up.
The excuse was in circulation before South Park.

Sure, but Scott didn't claim that they had invented that excuse, just that it's
seen common useage on that show.
