I have a trek oclv 5200, 1996 with dura ace crank and
bottom bracket. It has snapped. It says on the bb 7410 and
the number 103. What replacement options do I have? Will a
68 x 107 work just as well? What replacement do you like?

thanks jack

I've run my DA 7410 crankset with both 103mm (spec'ed
length) and 107mm (Shim UN-72 BB) spindles with no
discernable ill effects. This applies to both 7 and 8
spd setups.

There's no problem obtaining BBs with 107mm spindle lengths:
Shimano and others still produce them.

I know that Phil Wood still makes a 103mm square taper BB
but this is a pricey proposition. I managed to pickup a
discontinued 103mm spindle "Ritchey Logic" BB from
icyclesUSA.com <sp?> They may have others left.

DA 7410 BBs are still available as well as TA makes a 103mm
spindle BB. 107mm will make the chainline less than ideal.

Besides another Shimano, and the various other brands
mentioned, FSA makes several BBs in the 103mm axle length.
The "Ultimax" series - I would avoid the ti spindles if you
already broke a cro-mo Dura Ace.

With the relative popularity of ISIS & Octalink BBs now, you
can probably find an inexpensive 103mm BB on ebay or r.b.m.
