Posted a question over at the Bob list without comment, and I'm hoping to pick
up a fresh bottom bracket today. My question- with a suzie hub in back and a
white industries 16/19 freewheel on that hub, what bottom bracket width
achieves perfection or close to it when mounted to a

Some years ago when I emailed Grant to fret about chainline, he replied
that, if I am putting in enough miles with an off-center chainline

Well, except that with a triple you have a front derailleur to help keep
the chain from
I recently ordered a WI eccentric wheel from Anthony at Longlake Cycles. It
will be going on my Sam Hillborne, which is set up with a 113 mm BB and a
Sugino triple.
Will this result in the correct chain line with a freehub and the middle
ring of the triple?
The web tells me that this hub
The chainline will be fine from your description. In my opinion if you are
using a multi-speed chain, eight or nine speed, chainline is less critical
because there is enough flexibility in the chain to compensate being off. I
rode single speed for years and if it looked close that was good

Whether your crankset requires a symmetrical or asymmetrical bottom bracket
depends entirely on how it was designed. Classic Campagnolo Record cranksets,
for instance, use an asymmetrical bottom bracket, even though the inner face of
the crank spider is pretty flat.
Just one more example of
So Eric, would it be fair to say that the crankset/BB pretty much needs to
be purchased as a matched or mated pair? This, of course, is no big
deal if one is buying something like a Campy groupo, where everything is
set up to work together within the same product and model, but it becomes
That's exactly correct. The folks at Phil Wood, for instance, are in my
experience very knowledgeable about the length and style of bottom bracket that
will match any given crankset.
And ... to make things even more fun, there are slight differences in the
tapers on square BB spindles between
If you have a crankset that matches the Campy BB specs (length, taper, BB
shell width) for the cooresponding Campy crankset, is the Campy BB still
preferable?
Rivaciously,

That would depend on the BB and what your priorities are. Campy bottom brackets
from the classic era are rebuildable and can last pretty much forever if
they're taken care of. Many riders, however, prefer sealed units, which Campy
started making later on. I run both types on my bikes, and they
I've got my Sam Hillborne set up as single speed at the moment, using a
track cog, spaced and rear derailler.
The setup looks straight enough to my eye, but it does rattle a bit. I'm
wondering if I've got the chain line a bit off or maybe the spacers are no
sufficiently tight.
How does one go
