Elaborating on this would be valuable for the audience.

Why is it the only size 58 I'm finding with that long of a wheelbase? Most are around 20-15mm shorter. With my limited knowledge the 1020 just seems longer than what I'm finding on other bikes geared for racing. I'm sure it feels solid. How does the wheelbase number make you feel?

Which bike do you compare it to?
When I compare to the rose xlite, which this frame reminds me of, the geo is somewhere between sizes 59 and 61 and the wheelbase for these sizes are 1013 and 1027 so speeder lands right in the middle.

Looking at other racing bikes, the wheelbase does seem a bit long. Is it offset with a steep head tube angle and less rake?

A 59 and 61 are much 'larger' sizes. An SL8 and Factor Ostro Vam in size 58 has a wb of 1006. Cannondale SSE 1007. Size L(57.2)Canyon Aeroad is 1001. Y1Rs is around 1000. Cervelo S5 999.

I don't know what you mean by 'much larger sizes'. In the speeder geo table the largest size is 560, the one that assume you refer to as 58. But that 560 is just a length of a seat tube. When you look at the other numbers like top tube and reach, this size is something I would consider an XL. I am 193cm tall and this size is spot on for me(maybe a touch smaller than what I usually ride) but I'm probably on the higher end of the height range for this frame.

Hi Guys,
Long time lurker here. Based on what I read on the forum, several months ago ordered my first frame, the SC-R55D.
Coming from a rim brake SS EVO, I had high hopes and wanted something better than the Aliexpress frames.

Finally received the frame yesterday and I am not sure some things are acceptable.
1. There is a weird peeling near the front derailleur mounts(img_7247).
2. Bottom bracket, delamination(img_7243). This is the most worrying for me. Can it be damage from transport or it left the factory like this ? From what I know once it starts delaminating it is risky to ride, especially in the BB area.
3. Top of headtube, damage on the rim of the tube and on the bearing seat.
4. Seat tube, cosmetic damage on the rim of the hole and what looks like a lot of filler on the inside of the seat tube.
5. No di2 battery hanger included but 3 screws on the downtube. Where should I mount the battery, seatpost ?

I expected a perfect frame for the price but now I am a bit lost as it is my first frame buy.
Could someone please advise if these things are "normal" and acceptable to ride ? pictures attached

It looks like a totally different frame from what I had. The finish of my frame is way better and perfect (you can have a look at some pictures on this topic). It is even above of some major western brands.

I also received with the frame a Di2 battery holder. It is a small piece which looks like a seatpost clamp.

The battery is mounted on the downtube, right ?

Found it. All clear regarding the battery.

Is there someone skilled that can tell me if the frame is rideable or not ?

I'm sorry that you faced this.
I'd contact them as this is NOK.

My speeder was great but potential gaps in QC can occur.

I think it’s funny you expect a perfect frame for the price.

Maybe it's the pictures, but i'm not seeing what you're seeing.
1. FD mount. Looks like the paint just peeled off. Probably they masked the bolts, and the paint peeled off when they removed the masking tape. I wouldnt worry. Potentially, put some nail polish where the paint is missing. But that looks purely cosmetic, and you'll have the FD mounted there anyway.
2. i dont see delamination. Where do you see that?
3. dry fit a bearing and see if it fits properly. That imperfection isn't ideal, but i think it's completely harmless. Tolerances are much more important (does it fit without wobbling / rocking).
4. if we're looking at the same imperfection, then it's completely harmless to the point i probably wouldn't notice it.

If it were a spaceship, these things would matter. It's a bike frame. The internals on your pictures actually look super clean, which seems much more important.

Probably I stress too much as it is my first chiner but also my life depends on this thing so I want to be sure it is safe.
It is also for this reason I went with Speeder instead of other cheaper brands.
 
1. The box arrived damaged in the center, seems there was a hit on the FD mount. Upon additional check I can see a small bump on the inside of the seat-tube. Justin confirmed it does not leave the factory like that.
2. See attached photo.
3 + 4 the bearing and the seatpost fit well, so it is mainly cosmetic but still not on the Speeder level that I saw from other members.

In the seat post (like on the SL8).

I disagree :
1) The frame is not cheap compared to some OEM frames
2) Mine was perfect finish.
