I thought about getting a square-taper with cartridge
bearings; I would
have preferred it but couldn't find any cheaper options.
Just Phil Wood,
Dura-Ace, ect.

If you are intent on the cheapest possible fix you might
be able to
get a set of the old three piece bottom brackets with the
loose balls
and install that. From a functional point of view it is
probably as
efficient as the more modern ones and if you keep it
greased and
adjusted and will likely last a lifetime.


Well,,,,, I didn't choose the absolute cheapest solution. I
did want Shimano parts, and I didn't get the absolute
cheapest ones there either.

The UN55 is $24 and a Phil Wood BB would be around $200 (if
I saw it correctly). If the UN55 fails soon then I'll
probably want to spend more than $24 on another BB, but I
probably won't jump up to the $200 level. Is there any
square-taper/cartridge bearing BB's for $100? $75? I did not
find any.

I see the Shimano 105 has a road triple crank, but it has
the integrated spindle. Is it forged all in one piece, or is
the spindle pressed in? It would hit up near $300 for the BB
and cranks.

Separate cartridge bearing types start about $30 with steel
or aluminum (not nylon) cups. Phil cartridge $119, stainless
steel Phil BSC ring set $38. Phil titanium is more expensive
but not essential.

I have a couple of MTB crank sets with the hollow

crank. As for price try one of the other Shimano grades.


Well I suppose it would be basically the same, if the spindles are steel
and the cranks are aluminum.

The problem with shopping for other Shimano cranks/BB's is that many of
them don't (seem to) have road triples anymore. I still want to use the
($250) Rotor Q-rings I already have, and that requires a 130/74 triple.

Well, I suppose it is back to the two piece crank set but a Tiagra 3
speed crank set is around $100, or a little more.

I remember my dad, another mechanic, and myself all standing in the
pits chewing the sugar out of Wrigley's gum as fast as we could to
patch a gas tank.

The UN54 in my bike has gone tens of thousands of miles and is fine,
but if I had the dough, I'd be very happy with a Phil Wood BB (why go
halfway?)

Why, even a Phil Wood are two ball bearings in a shell, with a spindle.
Hard to beat a Shimano unit. I had a UN72 which served 8 years of ATB
duty and is now in a friends ATB.

Mr Muzi informs us that the unit cannot be disassembled, but can you
take the bearing seals out without destroying them? I would want to dump
some teflon in there if possible.

Mr. Muzi is right. There is no need to disassemble a Shimano square
taper cartridge unit. Install, ride the **** out of it and when worn
replace it. That can take a really long time. You be dead when you spend
as much money on Shimano replacements as you would spend on a PW unit.
Don't make it too complicated.
