Title: New(?) Riro Carbon Cranks anyone? ("Leese"?)
Post by: Wet Noodle on October 19, 2024, 06:30:11 AM
There are some carbon cranks on ali that look superficially similar to the lexon cranks (and other rebrands), just not quite the same (no indent on the show side, different axle and spider/chainring interface). I didn't find anything on these. Has anybody first-hand experience or are these already discussed somewhere?

Carbon crank arms, aluminium dub spindle, weird two-piece slide-on preload collar contraption, spider/chainring interfaces to the spindle (not the crank arm):

(https://ae01.alicdn.com/kf/S9b65431515794eb093d068066c372767h.jpg)

Cranks and axle seem to go for USD 150 and change regularly, but show up cheaper from time to time.
Suspiciously similar-looking cranks with the same type of axle (including preload collar and spider/chainring interface) are also sold as "Leese".

Theyre 400 g for crak and spindle, waste of money an material. Leese are 320 and much closer to a Cybrei copy

According to the product descriptions they'd be 30 g apart (400 vs 370). Where does the 320 g number come from?

Those, I have seen as well, but they are different ... and 3x the  price.

Part of the motivation for my initial question was the low price the riros sometimes go for (just yesterday, 135 USD for the bare crankset).

I’ve been looking them up too, for 150$ with BB and probably a bit less on 11.11, 150g saving is tempting

I've been using the 24mm alloy spindle Riro carbon cranks on my road and gravel bike with no issue. Those ones are now going for sub $100 USD during the sales. I wouldn't mind trying this new one, but there aren't many chainring options out yet.

So is this a proprietary spider interface?

I think it's a direct mount interface. There aren't many chainring or power meter options available yet.

Sure, the spider mounts directly to the crank. But it's not an existing standard, is what I mean. Obviously not Sram. Not Raceface or Rotor?
I'd be hesitant to bet on a new standard from some Chinese manufacturer that might be gone in a year or two.

I think it is Shimano direct mount. So I also think you can use the Xcadey power meter. But this combo will be a lot more expensive than the older Riro carnkset + P505 power meter.
And that is the reason why I decided to go with that last option last month.

We've put many thousands of km on race work carbon crank set. The rings do wear out, expect 25 bucks shipped and about 5k km. We have the old model that cracks on installation if you torque more than 6-7-8nm. 5.5nm has worked fine with loctite. I cracked one but was able to buy a nds replacement arm for cheap.
24mm spindle. 228g+152g for the crank set and 188g for rings. That's 380+rings.
I'm happy with them, they do the job. Whole thing is often under 150 EUR. The old design installs like Shimano so very practical.

I think that, too. Just for reference, comparison with a wolftooth shimano dm spider:

(https://www.wolftoothcomponents.com/cdn/shop/products/WT-SP-CAMO-SHDM-BST.jpg)


Sidenote: There was at least one listing of presumably the same crank (different branding, I think), where you could choose between 3 or 4 different interface types (meaning different milling on the axle interface, otherwise same construction). But that one was more more expensive.

I just noticed that ZRace, Passquest and Goldix all have 1x Shimano DM chainrings. Though there aren't many 2x chainring options and Magene hasn't adapted the P505 PM to that mount yet.

Leese just released a 110BDC 4 arm spider that is compatible with their direct mount cranks.

I purchased a pair of these RIRO cranks from here:
https://a.aliexpress.com/_EudctB2 cost me £119 delivered to UK.

Leese seem to have a pretty much identical option.

The cranks use a dub 29mm(28.99) spindle and the chainrings attach using the shimano direct mount standard, though unlike shimano who I believe use a lockring to attach the chainring, these cranks sandwich the chainring between the crank arm and a flange built in to the spindle.

I believe rotor uses a similar mechanism with their Aldhu cranks.

Unfortunately however, the spindle on mine appears to be undersized, and there is a tiny amount of play in the bottom bracket. I’ve tried two different BB’s with the same result. The spindle is measuring in at 28.92/28.93. So, I’m currently processing a refund. I’d rather the seller would just send a new spindle but that doesn’t seem possible.

A pity as the cranks otherwise seem good, look good (imho) and are very lightweight. 571g (165mm cranks) including spacers and preload ring.

Are you sure you are not using a 30mm BB or you need to use plastic spacers between bearings and spindle?

Post by: Charmander21 on November 30, 2024, 10:37:16 AM
Yes I am 100% Sure. I purchased both bottom brackets myself, they are both DUB bottom brackets. If they were BB30, there would be about 1mm of play which is massive, and the crank would be incredibly loose. This is much much smaller, but ultimately there should be no play in a BB. In terms of spacers between bearing and spindle, neither  BB camewith any additional spacers, and were both fitted as per instructions.


The currently fitted BB: https://primebikecomponents.com/products/bb386-bottom-bracket-sram-dub

I’ve also correctly spaced and preloaded the cranks, and maybe I didn’t make it clear but I’m not talking about lateral play (which would be the case if the cranks weren’t preloaded correctly) but vertical play up and down because there is not a proper fit between the spindle and inner race of the BB. I’ve measured both the BB’s I’ve used and they are within tolerance. The BB’s themselves have no play, (they are both new) which could be another explanation.

Photos attached.

You could probably try Loctite bearing retaining compound which not only keeps the axle in place but is also designed to fill any inconsistency in fitment. I’ve successfully glued in bottom brackets in pretty oversized bottom bracket shells like that. But I’ve never used it on crank spindles. But it could be worth a shot if there’s no other option.

That’s an interesting suggestion. I bought these off AiExpress ‘choice’ and so I’m able to send them back for a full refund, postage paid. So will probably do that. I may order a new pair from another seller.

The manufacturer for LEESE actually made more versions of the spindle that take sram 3 bolt, 8 bolt and easton chainrings but they dont seem to be for sale on aliexpress nor taobao.

Theyre visible in this ali listing but they're unavailable. same with on their taobao listing

maybe they had them produced but the sandwich mechanism for these interfaces didnt work? the three bolt and 8 bolt spindles have the cutout but there is nowhere to bolt the chainring on

That is interesting, I would prefer the 3 bolt GXP connection for the chainrings, it's pretty universal on Ali and easy to get hold of spare chainrings. That said, perhaps this will become more popular? Though aparrently this 'sandwich' mechanism is quite hard to manufacture. You can see a discussion of this in reference to the Rotor Aldhu cranks here:

https://www.youtube.com/watch?v=PX6nbV9s7SU

It's worth mentioning that there are 5 bolt 110 and 130 bcd spiders for these cranks, as well as the 4 bolt shimano compatible ones that Leese is selling. Just a pity that no sellers seem to have these parts available to purchase without buying the crankset as well.

Post by: Charmander21 on December 05, 2024, 05:18:06 AM
Just a quick update: I ended up purchasing a 'genuine' sram dub BB, I'd read somewhere about a sram rep saying that dub cranks should only be used with their own BB's. Sure, that sounds like marketing BS but I thought I'd give it a go anyhow, and to my surprise the cranks fit perfectly now with zero play. There's also no need for any additional spacers (aside from the 2mm 'road' spacer on the right side and the preload adjustment ring on the left) as the BB protudes slightly further outside the frame.

One other benefit is the plastic covers on the inner bearing races, that may help protect the aluminium spindle from wear.

the other two BB's that did have play were a Prime BB and a Z-Race BB that I purchased from Ali.

They had them in stock right before the 11/11 sale, but they sold out quickly once the sale started. I was tempted by the three bolt as that is the interface of my magene PM.

I'm very much liking the looks of the new Riro cranks, as I want to move to 165mm cranks on my Ultegra 8100 equipped race bike. But I want to use the original rings. I'm struggling to find someone that sells just the Shimano interface to 4 bolt 110 BCD spider. Anyone have any ideas? Would I just be better to get Lexon where they come out of the box like that?
