Shimano DuraAce 7410 bottom bracket cups

[Markmuso]

Hi,

I need replacement cups for a dura-ace 7410 bottom bracket
(103mm spindle), and am having difficulty finding these. I'm
not sure if the short spindle length requires cups specific
to this BB, or if any 'ol cups (english thread) will do. Any
suggestions? Thanks.

Your 7410 is a cup-and-cone style BB? Mine is a cartridge style.

If cup-and-cone style, I would think that any cups would work as long as the threading matched the BB shell.

FYI Mark, despite this crankset being spec'd for a 103mm BB
spindle, I've had it bolted to a Shimano UN-72 107mm BB for
2 years with no discernable ill effects. (If both BB's are
symmetrical the chainline only moves outward by 2mm )

Any set of cups from any of the cart BBs will work, like the
ones from a UN-72....

You can find a Shimano cartridge bb in 102 x 68 x BSC. I
believe that TA has one as well. A 107 is very easy to find
in Shimano and other brands. Some of the MTB type, i.e.
Raceface have the same unit for 68 and 73 bb shells.
