To complete my first impressions, this is what i think about my build.

With yishun rims GRL40c and 30c gp5000, the bike has a smooth feeling. Very composed when fast riding but also liveable when easy cruising.
Nevertheless as a carbon "race" bike it's not for bad roads with potholes, cracks, vertically stiff and not absorbing shocks, you have to watch where you put the wheels.

To me rear end seems locked resulting in a very good power transfert. But it's not giving me the explosive feeling of a bow you charge and boom, it's more neutral "ok i'm already at this speed".

I have no problem climbing with it, it goes very well. I'm suprised to get a light feeling under the pedal.
On the downhills it's fast and confident.

As a conclusion, considering it's the cheapest frame in spcycle store and in the market, it's a very very good surprise.

A gravel frame won't slow you down or marginally versus a road frame with same wheels/tyres.
I measured a 20 seconds difference between my road and gravel on a 17km road loop, easy tempo (z1/z2)

The gravel will be more stable and planted on roads where i clearly prefer the road frame feeling, but for pure gravel i will probably find the road too twitchy.

I was pretty sure that I was going to get this frame until I noticed that despite it looking like an Aeroad, its wheel base is waaay longer. Much longer than my current bike and I think the feel of that would just be much too different, so I think I'm going with an R088. Had to ask for the WB info from SP, but also noticed that it's loaded into bikeinsights.com

Do you take into account that the Spcycle r065 is one size larger than the equivalent aeroad? M r065 has 1cm longer wheelbase than S aeroad.
I have no problem climbing with it and it's fast on downhills.
 

they don't mention the distance in drops, but 16 degrees flare means, typically, 7-8 centimeters.
They seem to be a copy of (a copy of) Syncros Creston handlebar.

The og evkin has only flare, the syncros has outsweep and flare.
According to the dimension the og evkin is only 4cm wider in drops, mainly because it has a small drop of 115mm .
If only it wasn't so expensive i would have bought it, i feel a smaller drop more natural than 125-130mm where for me it's descending from third floor to cellar

Hello,
I received a medium frame with pearl white glossy paint.
Quality is very good, eps molding seems well handled.

About weight, i checked :
-seatpost 230g all included
-fork 422g uncut, 450 with axle
-frame 1177g with hangers, a bit heavy but i guess 1050 +/-30 claimed is totally naked
-frame + seat post clamp 1196
-rear axle 35g
-headset 101g

The axles are pretty light, i recommend to be careful with tightening torque and the quality of the tool you use.

Building the bike was easy, the right t47 is not as smooth as the left one but ok.

Some details :
If you remove the seat post the clamp easily falls inside the frame.
Due to the position of the seat tube, you have to consider that the seat post has almost 2cm setback.

About the saddle clamp itself, i had to sand a bit the top cradle because saddle was rotating, spcycle provide 2 cradle for different rails diameter.
There is no tightening instructions with the clamp, it be problematic with carbon rails as you need to tighten a lot to make the thing not to move.

The down tube is very thin, it's really easy to compress it with the hand but doesn't seem to affect ride and it's normal according to spcycle
Plenty of clearance with 30c, 32 as advertised will fit easily and probably 34-35 too.

About my first riding impressions :
Feeling is not harsh, vibration and small asperities are well filtered, surely helped by 30 tyres.
I'm pretty comfortable on the bike.
When it comes to big bumps, no surprise it's an aero bike.

The aeroad design is not fake, it likes speed, downhill freewheeling it gains speed fast.
In the wind, cross wind, it's pretty good too, i was expecting much more disturbance from an aero bike.
Probably helped by the fact I'm using only 40mm rims but the frame seems to let the air go around more than being pushed by.

Considering it's winter, i'm out of shape and i don't have enough comparison to give a good opinion on riding dynamics.

At the moment for me this bike is a very good surprise considering the low price.

You should check the famous Pat Lino on this forum or his youtube. He has done plenty of reviews of generic frames and big brands ones.

As a global conclusion, generic frames are very very good but the ride quality of a branded bike is more refined. I have the same opinion based on my experience.
Probably the difference will become less and less sensible as "chiner" really improve in term of quality, weight...

When you installed the shorter cranks did you keep the same crown, or did you put in crowns with 1 or 2 more tooth?

I kept the same size of chainring and sprocket. In my case shorter crank 165 vs 172.5 helps to pedal with moree velocity, i gained 5 to 10 rpm. I just use a biggest cog at the rear. For example i oticed on climbs when i used 39-25 with 75-80 rpm, now i prefer using 39-28 with 85-90 rpm.
Everybody is different, if you're very sensitive to your cadence and gear ratio, you could need a change in chainrings or in rear sprocket.
