Leese carbon crankset

does "not for fussy mechanics" mean it has the kind of fit & tolerance issues requiring some minor modification to the component (sanding, filing, etc) to install it?

I installed Leese crank a few days ago and the only annoyance i've had was getting the spacers combination right but that's just a "feature" of DUB cranks I think.
I used sram dub bb86 bottom bracket and i think the preload ring on the crank is too wide so you have to use a spacer on the non drive side just to avoid rubbing on the bb shell.
Sram suggests to only use 3mm spacer on the drive side but I ended up using 0.5mm on a non drive side and 2mm on the drive side. With 3mm total spacers it was a little too tight. Luckily Leese provides all kinds of spacers in the box.

Pavlo K nailed it ^

Spacers, correct orientation for chainrings, ride it after indexing

It's not a plug n play like a SRAM-SRAM of Shimano-Shimano system. I mechanic I dealt with was so fussy he quit working on it and even told me "your frame is fake"

In my experience none of the tapered spline cranks are plug&play you always have to play around with spacers/wave washers etc. The position the crankarm depends on the torque and tolerances on the spindle and the crankarm that vary from crank to crank even for the same model. So I'd say it's pretty much the same for Leese as for any other brand

Have you been riding yours?

On my 3rd ride today and threw the weirdest chainring-cassette combo. I'm impressed with the chainring. Again not the same as a real SRAM chainring but I don't see why anyone can't race on them

Have a planned 40-50mi on Saturday and can't wait to try it out more on more demanding terrain. I've done Tempo-Threshold efforts so far and not a single complain here

I've done two fairly long rides so far, and everything's working well. I'll definitely be swapping out the chainrings at some point though—shifting is decent, but they came slightly wobbly out of the box. Hard to complain at $25, but I'd appreciate any recommendations for a solid replacement set of chainrings. I was thinking these: https://www.aliexpress.com/item/1005008778249250.html?spm=a2g0o.productlist.main.9.53f5Jsa4Jsa48g but probably going to be just as wobbly. Any direct mount double chainring options for easton interafce out there?

The instructions that come with these cranks are pretty poor.

Cybrei’s instructions, on the other hand, are excellent. They advise using vernier calipers to measure your bottom bracket shell width, provide a detailed list of bottom bracket standards, and show the corresponding spacers or shims required. Since many of these cranks look very similar, clear and specific instructions like these are really helpful — and they’re readily available on the Cybrei website in English. The attached Cybrei PDF in Chinese has the BB spacing table.

I’ll also measure from the centre of the bottle cage boss to the inside of each crank arm to ensure the distances are equal. This can help identify alignment issues in some cases.

I’m using the DFS carbon crank, and they basically told me to follow Cybrei’s instructions, since they don’t supply their own as the have not managed to put on together yet!. I also contacted Passquest/Sprill, and they just sent me their standard instruction sheet again.
