Replacement for Shimano Decore LX
Hi
I have a old worn out Shimano Decor LX crank, 44, 32, 22 on a hollow BB.
Please can someone tell me what new crank I need to replace it with i.e. will the new Hollowtech II be OK?
Thanks
Pete

Generally it's best to duplicate the ring count and tooth sizes for a less involved replacement. What can change though is the BB axle size a different crank needs so assume it's replacement at the same time. As long as the tooth counts, the chain line and the BB size are all correct any type of arm/axle interface will work. Andy

Have you looked at just replacing the worn chain rings?

Changing out only the chainrings is what makes sense here. But if you were to need to change out the entire crankset, ebay has new Shimano Deore LX cranksets for reasonable prices. That's where I found a Deore LX crankset when I swapped out the Suntour that came stock on my bike when I bought it. Now my entire drivetrain is LX. Lighter and smoother. Love it.

while you're changing chain rings, it's best to replace the chain, too. And take a look at your cassette. It's best practice to have chain ring replacement coincide with installing a new chain & cassette, but obviously, if those parts are relatively new then you should be fine with just the chain ring replacement.

Now maybe the regulars on the forum care, I care to some degree, but the average person just doesn't.

The problem with this statement, and I see it all the time here, is that most people don't care. I'm not picking on you, just the general attitude that everyone wants a perfect bike. When I work on other's bikes all they ever want is a quick fix that'll work, not an entire rebuild. The average person is happy if the wheels move when they press on the pedals, not that it was able to shift silently while riding uphill, in the rain, with a 50mph wind blowing in their face and covered in mud. To most people you replace a chain when it gets rusty, but an oiled chain is fine no matter what condition it is in.

Well said
