Hi everyone, I'm Alessio from Italy.
Just received my new chinese frame and build will start in the next days
I choose an all mountain frame with 150mm rear travel and geo angles not too "extreme"; plans are to pedal this bike on Alpine trails surrounding my lands and weight will be a tad under 13kg/28,5 lb
Frame bought at Winow Sports, first time with this dealer and everything went fine, super fast with mine (many) questions! Delivery through WXY Express, quite fast (13 days with Xmas and New year between) and cheap
Frame quality is high, carbon inside is super smooth; frame hardware is good quality, heavy and matt black finish.Haven't check bearings yet, but will update this later
Mine is 19" size and painted in chameleon purple, weight is 2330 grams/5,13 lb plus 70 grams/0,15 lb for rear axle (DT Swiss style)
Setup
Cane Creek Double Barrel InLine 200x51 rear shock
Ohlins RXF 34 Evo fork 160mm
Formula Cura 2 pistons brakes in polish edition
Sram GX rear derailleur + GX trigger
ZTTO cassette 11/46
Fovno crankset (pretty a copy of Hope ) with 34T Oval Raptor from Superstar Components
Sram XX1 chain
OneUp dropper post
Wheels build with SuperStar Components V6 hubs, Sapim Race spokes and nipples, carbon rim 35/30mm from Winow Sports
Schwalbe Magic Mary+ Hans Dampf
saddle, stem and bar from Aliexpress

If it rides as good as it looks, you'll have quite a bike.

Nice looking frame. That supplier (winow sports) is not one i was aware of until now. I googled their site. Do you have a link to your frame - i couldnt find it on their site. I am interested in the geo etc.
That frame sure is light for a 150/160mm build.
i am also intrigued by some of the components you put on there. i've never noticed that crank before - i looked it up, and the one site i saw (a malaysian vendor) suggested the chainline is 48.5mm. i'm had a look at those superstar chainrings. am i correct to assume that you went with a BOOST version of their direct mount chainring?
-
You could find this frame design also at BXT and some other dealer, this is the link

Crankset is on delivery, maybe next week; I went for the spiderless one, it's a Sram direct mount interface and chainring is a boost offset (+3mm)
They advertise as GXP standard, but axle is a straight 24 mm, so is a Hollowtech Shimano/RaceFace X-type

Had bad luck with chinese carbon crankset some years ago, but this alu seem to be really well made
-
this is the geo chart
(https://i.imgur.com/gzcYyrc.jpg)
Mine should have a 0,5° slacker head angle due to the Ohlins fork at 160mm/573mm A/C length
Chainstay are on the long side compared to other frames, but should climb well planted (I ride on some very steep uphills) and fork offset at 46mm should help with agility

Which Shock size are you using? In the German forum there is problem about the shock size... There is nor Shock which will fit?!
https://www.mtb-news.de/forum/t/china-rahmen-erfahrungen.807207/post-16290899

I have a 200x57 as per specs
Shock hardware is 22.0x8 mm both ends
-
Seems to me they tried to install a 210mm shock length...200 is the right size!
-
One aspect that need attention is seat tube length because is short;
at 19" size is only 45cm and max insertion for seatpost is 16,5 cm
Once I'll pedal it and found my correct height, I'll buy the longer possible dropper post

The Problem is that the Crosslink of the rear end are collided with the seat tube when the shock is using more then 47mm shock hub?! Can you try this please?
-
I'll check within the next hours and post my result here...this would be an enormous mistake
By the way, from my pic seem that I have more clearance from seatstays arch to seat tube than shock stroke; in the deutsch post the crosslink seem shorter than mine, as it's from the XC frame similar in shape but with 100mm rear
-
ok, I've checked frame and shock strokes and I have to admit the size error! At 150mm rear travel, linkage run 51mm, so the right and only shock size is 200x51mm.
A bit frustrating 'cause now I have to ask Probike Shop a swap with correct size
Hope this help someone in the future

An update to this frame shock size problem, at least in Large size.
After testing 200x57 and 200x51mm size without success, today received my new DVO Topaz 210x55 metric (will go in the Santa/AM831 frame) and find it can be a solution.
Max eye to eye length for this frame (in Large) is 207mm.So I mounted the shock decompressed by 3mm and tried to cycle it at full stroke; well, it run 52/52,5mm and bottom out leaving a 2mm free between seatstays arch and seat tube.
Well, I'm not happy at all because an error in this project do exist and vendor couldn't fix it at the moment; by the way they tried a 200x57 shock, sent me pics of this, but have no answer yet about striking issue...
Tried the bike in 4 quick rides with previous shock (Cane Creek 200x51) and found it quite funny, pops over small terrain feature effortless despite long chainstays, track well over rough obstacles and turn easy in narrow trails (running an Ohlins fork @46mm rake).
Overall a nice riding AM/trail (pumped) bike, only thing I don't like is the flexy and bouncy feeling I had pushing it through berms; seem to flex to the outside of the turn and then bounce back to inside as a reaction.
Want to work more on this, probably could improve this aspect fine tuning the shock.
Will try to test DVO this week (now with 2 spacer in positive air chamber) in the hills behind home...unfortunately Italy is locked down in quarantine due to Covid19 at the moment and can't reach higher trails.

What a pretty bike! Sorry to hear about the shock problems, that might kill this build for a lot of people! I love the look of it though, throw some labels on and it could be a main brand factory anything. Some of these manufacturers have come a long way from the weird scott spark and specialized cross front triangle obvious knockoffs.
-
yeah, I like it a lot, simple design with horst link, good overall quality frame and pedal really well uphill, funny downhill...I'm waiting for vendor (or manufacturer) to fix rocker arm error.
By the way with this shock length it work.
Will sell it as soon as they'll address the error to make room for the AM831 from Haideli
-
so, finally had an answer from vendor; they found I'm right, size Large strike seat tube and now they re-design the whole rear triangle for all sizes, because is the same.
Once it will be ready one will be shipped for free.
-
I have the 100mm travel version of this frame. I bought it before they came out with this one :-\
Glad to see one put together, looks great!
Ive noticed that the 100mm may be hitting the seat post as well.
-
oh really? I don't understand why customers don't leave or report this kind of things on feedbacks...
Very nice also the XC version !

I ordered mine from AliExpress so there’s been a bit of a language barrier the couple times I’ve contacted them.
However, while ordering from Winow, I felt very comfortable with them and have been able to communicate quickly and easily.
My rear shock actually got in the “stuck down” position and was in a bit of a vacuumed state so I think my rubbing was probably front that. I threw some mastic tape back there either way.

I also had great communications with Winow, what I liked less was the delay in answer/reacyion after I gave them the proof of the project mistake.
Now I'll wait for the new rear triangle, that I'm sure will take few time.

Freeride, did you receive your new rear triangle yet?

i'm also looking at a bike FS030, xc bike with 120 mm rear travel, from http://www.winowsports.com/ so any updates on this frame or vendor are appreciated.
