can i run a phil wood bb in iro mark v
the iro website says that the mark v takes a 68 x 110 bb. sheldon brown says that phil sells 68 x 110.5, but they are both campy specific, otherwise it's 68 x 111. forgive my ignorance, but is that completely incompatible or just a matter of an extra spacer in back? thanks.

i've since read a bit further and discovered that the bb's are adjustable. woops.
at first i'll be using the stock FSA cranks...the plan is to slowly upgrade all of the bike's parts. during that process i will teach myself to overhaul what i've replaced, and eventually will buy myself a custom frame that all of the fancy parts will go on. then the IRO will be in good shape again. this process will likely take a handful of years.

bb's mate with cranks. get your new crank before you get your new bb. or just forget the crank business and upgrade the wheels. phils laced to aeroheads.

They are adjustable in the sense that you can shift the bb in the shell. So if you get some *****in' big spindle size your pedals are going to be shifted underneath your feet way too the left. .5 mm will be nothing though, that phil one with work.

The only number that really matters for frame compatibility is the first one. The 68mm is the width of the bb shell. Italian frames are 70mm, most aluminum and oversized steel frames are 73mm. As long as you get the right shell width and threading (i'm pretty sure all frames use english threading now) you can put any bb in any frame. The second number is the spindle width. It will determine where your cranks sit, which will affect the chainline. As for "campy specific," I would imagine that has to do with the dimensions of the taper. Campy uses ISO, while sugino/shimano/most others made outside of italy use JIS.

and seriously, i have a propensity for aiming right towards the hugest road gashes anybody never saw, so it'll most likely be phils laced to deep v's.
