LEXON Road Carbon Crankset

If you ordered the crankset separately from the powermeter, there may be an issue with the crank lockring as pictured

The lockring can be hand tightened in but the grooves have no space for tools to fit in and tighten it. However, this may not be the case if the seller is offering a mounted crank unit to the powermeter as mine came separately.

The solution is to use an internal groove lockring like the Race Face CINCH for Easton lockring. Small hiccup but not catastrophic so the project will be delayed while I use the standard alloy spider  that came with the crank.

It is installed but without powermeter until I get a replacement lockring. The bike went from 7.4kg to 7.1kg in a single swap of the cranks.

One of the AliExpress sellers replied that the tool needed is the Shimano TL-FC33 adapter.

We tried that but the flange on the tool is too thick. I have ordered a RACE FACE -CINCH lockring with internal splines instead to test. So stay tuned.

That sucks.. because that's the tool the seller recommended when I asked if tools would be provided

Let us know which one works.

[Taicho_Cyclist]

Got it. Will keep posted. I also ordered a RISK brand version to test.

My seller is going to send me the correct lockring with internal splines shortly. Hope that can come and sort out the powermeter installation soon.

The tool for the lockring looks like a 20tooth BB tool correct?

You are correct.

What is the tool you used to install the lockring? I tried a old 20tooth square taper bbtool but it doesn't fit exactly.

Can you point me to the right tool?

I am getting fed up with the Lexon store that sold me the crank and powermeter combo. It seems that they do not know which is the tool that can install the spider. They pointed me to Shimano TL-FC33 which does not fit at all and now they are not replying.

Lexon is one of the less trustworthy brands according to reviews. This just adds to that image...
