That's the "famous" sl8 clone with a different shape for the head tube and fork.
Geometry is the same and everything else is the same too.

Geometry is slighlty different.

Why is it not the SL7 then? XD

That does NOT look like a BSA BB. Looks like a T47

In what size, with what paint finish, and what hardware?
And do you have a supporting photo?
And can you give us an idea of how much T1000 is used in the process, vs 700 & 800, in %age terms?

I also thought it was a 1:1 copy of the SL8 clone, but that head tube and fork are different. I'd be inclined to think SPCycle has a separate production batch of this frame that differ from the other clone versions. Plus this one is confirmed EPS molded, which the other clones have not made claim.
I've bought from SPCycle before. They have some of the fastest shipping and my frame has been running great.

T47 is definitely wider, that does look to be threaded BSA.

Size 54cm, Matt black color, frame 861G (including UDH hanger), Fork 400G, Seatpost 172.5G

I would have sworn it looked too big for BSA. Must be the narrow tubes...

You guys have a good eye for detail. All these bikes look the same to me and need a geo chart to pin down details LOL. I would love to see some interesting designs along the lines of a Pina X frame or TideaceBike FM-CR068. It explains why I love my SP G056 so much along with the fact it performs so well. To be fair I am REALLY lusting over a new Pina X frame so much I may get one in the new year.

from the photos it seems that the scale is disconnected from the power supply ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D
it's magic

A miracle similar to frames made of 100% Toray T1000 Carbon. ;D

Don't forget the FD hanger is mounted backwards as well! ;D
I really hope those are hex screws and not riveted in!

Never heard of those magical things called "Batteries"?
If you search for this type of scale you will see that they can work with AC or batteries.

no. you can pass a link?

In all seriousness though, this frame really ticks a lot of boxes. The weight seems decent, confirmed EPS molded, I can pick up a UDH hanger anywhere now ($16 USD on US Amazon), I have a bunch of spare threaded BSA BBs laying around and wide road bike tire clearance. I could potentially consolidate my road bikes and just run different wheelsets for climbing or speed.
-
Choice is hard between this one and TT-x68.
-
small important detail: they don't have size 58, the usual Chinese ones.
I have to discard it

And this is my problem also. I ride a 58 and very few of these frames come that big.
-
They claim 40 % of T800 and 60 % T1000. What do you think ?
-
size 58 will be available from February, reply from email sent by david from spcycle.
they don't have a shred of integrated handlebar to buy, you have to buy it separately

I have the same scale, it runs on internal batteries that charge via that cable you see unplugged ;)

How about 60?! (I know this will never happen for a frame from China :-[ ).

If it makes all you tall riders feel better, I can't dunk a basketball! ;D
I messaged SPCycle and they said they have R088 raw frames ready to paint and ship. Last time I ordered from them it took 10 days for production and 4 days shipping to my front door in the US.

let me be a bit suspicious about their EPS technology!

The Hygge Model S is also EPS molded and that frame comes with handle bar. Actually the price on that frame with BF pricing and coupons looks really good right now.

i have no idea of the cost of the technology
but chinese know how to sell with the mandatory words . lying is like telling the truth .
we need proofs
Maybe they use it , maybe not ;)

only really cheap (several years old velobuild frames) are NOT EPS moulded these days. It's easy to tell looking inside the frame. if it's clean, it's EPS moulded. If it's full of wrinkles and glue, it's bladder moulded, and i wouldn't buy such a frame, because for another 100 bucks or so, you can get an EPS moulded frame. The probability of delamination / carbon failure is higher in bladder moulded frames, because compression is much less consistent. It's also easier to route a frame with clean internals, and it's pleasing to have a frame that looks well made.

easy to say only when the frame is already between your hands, ready for a coelioscopy of the the down tube. but before sending the money?

It's easy, ask questions. Honest sellers answer them. You're also less likely to be shipped a shitty frame if the seller perceives you as someone who is more likely than average to notice problems. When you sell things to people who have zero understanding of what they're buying, especially with his Chinese culture is, it's very tempting to meet quality fade. Asking questions is a good quality fade hedge.

another clue can be the weight, no doubt that EPS molding save the weight (one big layer is better than several small layers), more than 100gr for sure
but if i compare to western compagnies , i have some questions.
For example canyon is famous to build the thinnest (and fragilest) frames (the process is pretty optimized), the ultimate frame is given for 1050gr(cf), 850gr(slx), 730gr(cfr). if we ignore the CFR which use expensive HM M... carbon fiber, i wonder how can OEM chinese factories reach these weights with thicker frames (even by using EPS molding). Giant TCR is around 850 gr too, maybe helped by the slopy frame.
With my short knowledges, i understand the following facts:
high modulus means same stifness than low modulus with less material, less weight but fragiler due to a smaller tensile strength
T800 and T1000 show the same stifness but T1000 is 10/15% more robust and 10% denser
T700 is 20% less stiff than T800/1000 too but slightly more robust than HM carbon fiber (starting by M..)
T800 is at least 30% more expensive than T700
So how can chinese OEM factories produce the same weight than a slx with ticker frames, with probably the same fibers (not the same supliers or/and coating), and with a less controlled distribution of fibers? i use to say to an friend who is astronomer: dark matter takes place within chinese carbon frames but weight is missing.
-
I think 800-850g seems reasonable for an aero'ish T800 carbon frameset. All these companies say they're T1000, but that's just part of the marketing routine to rope in the noobies.
Anyways, just pick a vendor that has good communication and answers your questions. Though if they keep calling you "friend" in every reply, they're probably bullsh*ting you! ;D

T800 carbon is stronger and lighter and 11% stronger than T700 in terms of tensile strength.
T800 is also slightly stronger than T700 in terms of compressive strength too.

Winspace has built the SLC 2 with an unknow proportion of T700/T800 around 800gr before painting, but i believe that's a serious and reliable factory with optimised process. it s not properly achievable by all

As someone who has been buying AliEx/Chinese components the last few years, I've started to see a pattern of optimized manufacturing processes. There are cases when things get sloppy later on, but I also see refinements and maturation of products. For example, I feel sub 1300g disc wheelsets are starting to become the new norm and ultralight wheelsets are now going down to 1100g and less. As they've improved the processes, prices have gotten cheaper as well. Same goes for carbon cranksets. They're becoming lighter, stronger and affordable.
If you feel more comfortable buying a Winspace, go for it. I'm not trying to convince you otherwise! Personally, I somewhat enjoy the challenge of making this stuff work properly. There's a certain thrill of the DIY'er mentality. Other people prefer stability and security in their purchases, and that's okay as well! ;)

it s not a question of buying easter or western. it s a question of buying a mix of acceptable stifness and safety.

when will size 58 be available?
Size 58 has completed mold development and sample testing. It will be available next week.
