I'm on Tiagra 4700 10s here so not the usual 11/12 speed groups which are more common around the forum (here in Brazil groups are really expensive so I'm still holding on the upgrade)

I usually rely on KMC X10 which I think offers a good cost-benefit, easy to find it for 20usd (or less) on aliexpress and last 7-8.000km or more depending on ride conditions

I've had one shimano 10s in the past, but I got it too cheap and think it was fake, before 6.000km it was already >0.7 wear...
it's easy to find cheap ones in Aliexpress too, but then I'm a bit concerned about the quality, and prefer to risk it on the KMC's - which I know there's a lot of fakes around, but even if the ones I got are fakes they at least lasted long enough

then right now I'm trying out the YBN, got a good value on a 10S one, it's about 2.000km and all good by now, but still a lot to ride before making my mind

the YKYWB socks I'd not recommend, I've got like 3 pairs - all received as gifts on orders of 2+ pieces (just ask and you should get some gift too )
after some months of use the fabric gets loose, not enough anymore to be tight on the shin and just drop to the ankle, so not good.

Spexcel ones on the other hand (also received as gift upon asking) are really good, nicer fabric and finishing, and are holding well over 1,5yrs of use

I've also got ones from the same 'sportspy store', with some kind of 'mesh' fabric (here), these ones impressed me, high finishing quality and comfortable fabric, and are pretty cheap too

the Liteskins I've never tried, I've got a bit frustrated and traumatized with 'common' fabric socks (not the tight aero with silicone style) I've got in the past which got loose too fast - they were the cheapest ones too, so bad on my side anyway lol

ones that I'm really curious lately are these ones from GRC - they seem like a more boutique brand from China, lot of more expensive products but also some more affordable ones, not a lot of sales on Aliexpress (seem recent) but the website and instagram looks good
at this price and with the extra discounts, seem like a really good deal, unfortunately, I'm over my budget right now so will have to wait a bit to check it out (also I have too many socks lol)
the store also has some more aero options, and merino too, but much higher price point.

I need new cycling jerseys for road biking. What's the latest word on DAREVIE and SPEXCEL?
Any other brand recommendation?

Take some time to read the last ~5 pages, there's a bunch of reviews and feedback about both these brands and YKYWBike too

From my experience, Ykywbike and Darevie are the way to go, more trustworthy products and good aftersales - I always can negotiate some extra coupon when placing an order (except over big sales, like right now), and the few issues I had I could work out through the chat and get some discount or gift in the next order.
Now, Spexcel also has nice quality (I have 3 jerseys here and all good >1,5yr of use) but lately I've seen diverging opinions, some people having quality issues with them. Also, the aftersales is bad, they don't talk much on the chat and the time I had issues (dimensions different from the size table) I could only work it out with a dispute. So although I still look for their products, I take it a bit more as a gamble than the others...

The 22.70 is indeed the normal price I also see when I go trough the shop itself. But in the Android app on the main page I these "Super Deals". Prices here are lower but most of the time the colours and/or sizes are restricted... The price I see now is 18.89 USD. There is for example an even lower price for these shirts, but only available in red or orange and sizes M and up. I need S so I could not use that. Price for those is 15.59 USD at the moment.

I am a diamond member, so maybe it has something to do with that?? They claim I get 15% off because of this status, but I never thought that was true...

yeah, the account level influences from what I know, but also changes according to product and color/size, there are very specific promotions
looking at the Super Deals page is always good practice, Darevie, Ykywbike and Rion have been doing frequent sales there with special prices, but also limited quantities, so need to be quick

I recently switched to narrow drop bars which didn't fit my bar clamp gps mount, so I had to get a stem gps mount. I ordered the OG-EVKIN stem gps mount and the quality is top notch. The carbon mount is well-machined and solid and the mounting hardware is very good. It even comes with a pair of M5x30mm rainbow titanium screws.

I'm really impressed by the quality of hardware coming from both LEXON/RYET and now OG-EVKIN. There's a lot of shade/hate being thrown at AliEx bike gear, but at this rate this stuff is going to surpass western brands.

my whole cockpit is og-evkin, the mentioned mount CM002, plus HB002 and SM004 (the exact combination in the description of the link you shared, lol
each part is really well finished, it's 2yrs of use and all good, I only had some issues with the torque, it requires a bit over the spec to properly fix, but other than that all good

recently got 2 new pieces from YKYW
this shirt which the fabric seems a bit different then the others I have from them, nice touch and comfortable, good fit.
and this windvest which I'm honestly impressed. The fabric is light and comfortable, it has a type of lycra on the cuffs which help a lot with putting on/taking off, it's well ventilated but I still was well protected from the wind and cold (7 deg C riding with base layer+jersey+windvest, and all good)
It's a major upgrade on the old windvest I got from them (one of the cheapest)

it's just first impressions and still need to check the durability, but it seems good by now

YKYWbike: Love the atheistic of their jerseys, but realising they are deteriorating faster the most others jerseys ie 10 to 15 rides and they are worse that jerseys bought over 5 years ago with 50 or more rides in them. Bought their Korea lycra cargo bibs, first impressions great, so I bought a second pair with the Elastic Interface pad, but again after regular use (maybe 20 rides each) the soft, compressive lycra is a little harsh and lost some compression. Really rate their base layers and socks.

nice post and thanks for sharing the experience!
interesting take on the YKYW, for me it's the other way around, some of the best experience and like 70% of my weardrobe it's from them...

the shirts seem to loosen quicker, but still get 1,5yrs on them until it starts to be bad to wear.. but the bibs I got from them are all still good and compressing well, even after over 2yrs of weekly use

The first one you linked. I don't really do rides under 3 hours so I'm skeptical of any "good for short rides only" reviews

yeah, I have these ones in blue with the purple chamois (Venom90 it seems to be named). The quality is very good, and to be honest seems to be the best at this price range, fits very well, it's comfortable.. all good
For me it works really well for 3-4 hours, above that starts to get a bit harsh. But be aware I'm 62kg lol

just a +1 on the Lexon saddle (Ryet Aircode is the model, if I'm not wrong), I've commented some pages ago but I think it's worth mentioning

the construction is really well done, the rail bond as mentioned is much better than most chinese carbon saddles, the 3D is 'simple' but seems good, been 3 months and it's holding well I believe (and hope) it'll last long.. Shape is a complex subject, it's too personal, but I've adapted well to the 'pro stealth' shape it has, the wider nose and the relief channel I like a lot, no discomfort in long rides

as far as the advantages of the 3D print surface, I honestly think it's still mostly marketing at this time - even if you go to the top of the range ones, from Specialized, Fizik, SelleItalia...
it really doesn't seem to do anything much different then a good advanced foam padding does. Dif density is something doable with padding, the weight is not so different as far as I know. Maybe one benefit is that the 3D structure keeps it's shape even after long hours of use (at least theoretically), while foam is bound to compress and require some time to go back to the original shape - this could impact comfort in really long rides.

Does the mesh style top not get dirty? It looks like nightmare to clean

I ride road only so it's a non-issue (at least by now), so mostly the dirt and grime stays in the wheels and frame but not up to the saddle. I tested throwing some water in the 3D structure and it drained well through the sides, but am not sure if it can clean a lot...

for mtb or even gravel, I think would be something to be much more concerned about, though. If it's only dirt, maybe some water would be enough, but sure would be a nightmare if the dirt gets really inside the structure - probably would need to remove it, let it inside a bucket deep in water for something to soften, then get out and be able to get it clean..

from what I understand, there are some different scenarios...
a. open mould frames, often different companies operating within the same factory and sharing moulds
b. replica moulds, reverse engineering to get to a frame design but with slight differences
c. counterfeit moulds, chinese factory manufactures for western brand, normally it's in the contract they should destroy the mould after the lifespan but it ends up continuing to be used - either the same factory or a friend/sister chinese company

If I remember correctly, it's Elves that produces (some?) Cervelo frames, I think that on some Francis Cade video he inspected the frame and it had some cervelo inner parts which indicated 'same component/same factory' situation. Or like this Ican/Factor situation below
I work in the home appliance industry and we go through similar stuff with our chinese suppliers/factories.

The thing that most people get wrong is that the manufacturing process and quality verification are much more important than the mould
if the chinese company just uses the same mould but has a shit process, then it's going to be a good looking frame but shit riding, and unreliable

that's not to piss on all replica frames, just that it's not that simple.. I honestly think that there are some companies that make replica's and could have a good process.. just that personally I prefer not to endorse and go with an open mould, for instance

Is it the same mould? I remember chris miller mentioning that some chinese company that does direct to consumer had the factor moulds and would start selling them this year, people were saying ICAN tho.
