Just received the LEXON R1 hi-mod carbon cranks today and they are really beautiful. Did a quick unbox clip just to show the item and weight, plus the accompanying Xcadey Powermeter which will be mated with the carbon cranks.

Seeing is really believing as the weight is amazingly light at 331/332 grams for cranks with spindle. Adding the alloy spider gave 372 grams. After replacing the crank spider with the powermeter, the overall weight without chainring bolts is 435 grams. Still amazingly light before installation on my TIME ADH23.
Cheers.

How much did you pay and where did you find them?
-
The cranks are from Aliexpress for about nearly USD200 and the powermeter are about USD270 with discounts using coupons.
-
Interesting. Isn't that more of a MTB crankset? Is DUB for road too?
-
Dub is very much a road standard too, and it's basically a slightly aesthetically tweaked cybrei crank
-
I can't find them at all on ali, only under the elilee brand at double the price. They look great though, what chainrings are you pairing them up with?
-
Theres like 20 listings for these cranks and elilee is a completely different brand
-
Suspect IMO. Why would you have that indent in the arm of the crank? It looks like they tried to make it look 'cool' like a CNC machined alu crank.
-
I wish this came in 165mm.
-
4 sizes from 167.5 to 175mm
-
ordered one! hope to receive it in few days
i plan to use it with a 1x setup for gravel.
-
Do these have any advantage over your normal SRAM RED 8-bolt Crankarms?
They seem to be the same weight and apparently only $20 cheaper.
While I appreciate the competition of Cybrei, Incolor and Lexon, am I jaded to expect at least a little more of a price gap considering the unproven durability and lack of local customer support/warranty?
-
they're a little bit lighter, the wight is quoted with the spider
-
Are these dual sided by some miracle? My DUB Zero PM only reports one side.

They are spider-based (so measure power transferred from your crank axle to your chainring) so they give an accurate L+R combined power measurement but are unable to give independent power readings for the left and right sides.

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.
Right view.

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.
-
Got it. Will keep posted. I also ordered a RISK brand version to test.
-
mine is arrived, and have the lockring with internali splines
-
here the weight, the chainring si a passquest oval 42t

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...

can you post a photo of your lockring?

I have a old 20tooth BB tool that I used to remove square taper cranks years ago.
It looks almost the same but the splines on the tool are slightly too thick. I have tried ordering another one to see

3d printing may be your friend here. i have 3d printed a couple of strange tools to tighten various BBs. From memory, I think i need to print the tool to install a Moqai T47 BB, for example.
Thingiverse is likely to have the tool you need, then you simply have to print it. if you dont have a printer, make a friend, or find locally. it's become so common, it can't be expensive to have it printed. it costs me pennies to print such tools. Basic PLA is sufficient if you know what you're doing.
It's amazing that the shop selling these is incompetent to the point of not knowing what's needed for installation. Very hard to respect that level of incompetence.

They keep recommending the Shimano tl-fc33 which is clearly for external splines where as the powermeter comes with internal spline lockring.
