My chain rings are through again but replacements have

It's now much cheaper to buy a simple crank set of
another brand.
Preferably steel because aluminum wears so fast. What I
have is:

Shimano 600EX, 52/42T, bottom bracket is 116mm JIS taper.

What I'd like to replace it with is this Vuelta Corsa
set:

Only 50T which is kind of ok but the 32T lower will move
me up hills
much better. Getting old, and all that sort of thing.
However, says it's
for 110mm BB and I wonder if my chain line would go out
of whack. I'll
ask on Amazon as well but usually there aren't good
answers that way.

My shifters are simple friction levers and the front DR
cage looks tall
enough to handle the 50/32 step.

Do you guys think this would work?

Long story short, I ordered the 53/39T Version with 130mm
BCD - junk.
The cheap bolts were overtorqued and two of the Allen
inserts stripped.
Plus they didn't send Vuelta Corsa but some no-name that
was quite
scuffed up. Goes back for a refund :-(

That what I would expect from a 36 dollar crankset....junk.


I have seen good ones in that range. What is cheap were the
chain rings which are then steel. However, that's right up
my alley because I am after durability and not a weight
weenie.

Thing is, what they sent were not Vuelta Corsa. Now I'll be
looking for steel chain rings with 130mm BCD because my
cranks set itself is still good.


Given your riding conditions, style and comments here, $36
for two steel rings is a really good value to you. Recycle
the arms and you're still way ahead.

*nb* Steel rings are frequently thinner than aluminum
rings with a milled recess. This is shown mostly by the
chainring bolts being damaged from overtorque while the
rings still rattle. Check that and add a spacer under the
nut side as needed.


Darn, I already did the return thing. Mainly because I could
not get two of the bolts out. They were overtorqued and then
the hex pattern stripped out of the cheapo material. Could
have somehow drilled them out I guess. This also gave me the
feeling that the steel rings are inferior material as well
and would wear off quickly.



Where wear is critical (high torque rider, excessive dirt, high mileage
etc) ...


That sounds like me :-)


... steel rings are an improvement. Notice that many cranks come with
pretty milled and pinned aluminum outers but steel inners.


So far I haven't found much 130mm BCD stuff in steel. If I really can't
maybe I order that set again and then drill out the bolts to scavenge
the chain rings. It's probably not very good steel but better than nothing.
