I'm not a machinist or an engineer but it looks well made. Seems are tights and no excess material anywhere. The marble effect looks A+

The big difference is that the Leese version is available with an Easton interface, meaning that there's a range of spiders (and power meters) available so you have a significantly better choice of chainrings. The Riro version uses the Shimano Microspline interface which is only used for Shimano MTB cranks, so you have basically no choice of road rings other than those on AliExpress.

Just wanted to add that Leese goes all the way down to 135mm for Carbon cranks. Perhaps good for children-shorter riders

I don't know who else offers these lengths. I'm personally going to experiment on the 150mm which is not readily available elsewhere

Yet another entrant in this now crowded market

Thought I'd give this a shot for its low price (ended up paying $118 with the current Ali coupons). It'll be paired up with some Sprill (Pass Quest) chainrings with my AXS groupset

Bought the 150mm option under the LSE-C01 pro (110 BCD/4 Bolt). The 5 bolt option is another product with different crank lengths

Expected weight is around 400g for the crank+spider. Another 175g for the chainrings

According to the manufacturer:

2 yr warranty and "We have been selling for 2 years, with sales exceeding a thousand, and have never experienced any quality issues"

CNC machined axles
Aluminum

Taicho_Cyclist was first to post it on Chinertown and found his comment. I will encourage him to engage as he has the crank installed but is still building his bike

I will update this thread once received and ridden

Yeah the pad is pretty good, on par if not better than the Ykyw EI-pad (that seems to be almost gone now).

Only problem with these bibs is the lycra is very thin and it’s seamless, which makes me feel a bit naked, so I never bought more than the pair I have.

Are there any brands out there that have thicker Lycra?

Tempted on the Lameda but I've exceeded my monthly spend on bike stuff. Need to hold off a bit with the YOLOing

@PeterXu do the factory and designers making this have experience making big brand or Chinese brand thermoplastic cranks? 

SRAM had early problems with delaminating inserts and a few cracks.  Easton had a lot of issues early on, and still some now.  Various cheap Chinese ones have had the same.  Quality Chinese ones from Incolor and Elilee both had extensive issues initially.

I.E. If the factory and designers have experience, we might expect the launch product to work fine.  If not ... I think it may be a mess.

I guess we're not getting an answer this @PeterXu?
