What do You mean by least compliant? Im ready to pull a trigger for SC-R55D in change of my Bianchi Sprint.

Would it be harshier even after putting 30c instead of 28c?

I have no clue about SC-R55D as I never rode one but yes the R48D was not what I would associate with comfort however it did have some nice traits - great sensation of power transfer/planted on descents and cornering.

And I would definitely put 30C tires the R48D has a 28C clearance so that's what I had on.

I bought the frame in hope it will be slightly comfier than my previous bike yet good for racing.
I've had many bikes before, so you may wait a little until I finish my build and write a review :)

I don't find my bike harsh at all.  Currently running 30 or 32c tires depending on which wheelset it the flavor of the wind.  Took a hot minute to track down all the creaking. Turned out I forgot to carbon grip the seatpost....  Oops.

Did a century a week and a half ago, put 1500 watts out last week, and have even gone down a few gravel roads. Only on the gravel did my Addict Gravel feel better.  Other than that, I've been quite pleased.  One day I'll hop on a "real" bike and get the full comparison.

I would not say the bike is harsh, I was pretty happy with it until I rode my endurance bike again and I think that Rose is just on another level it terms of comfort. It spoiled me

Thanks for sharing your experience. I went on geometrygeeks.bike to compare both bikes, and the geometry is so different i'm actually lost, which tells me you dont belong on a race bike, just like most people, and it's absolutely fine.
Also, that Rose Reveal looks really nice, actually!
Given that Rose is a catalogue buyer of chinese frames, and that Speeder is a revered OEM manufacturer for companies like Rose, i really doubt that Rose bikes are intrinsically better than Speeder, but it does sound like you found a geometry & frame that work for you, and that's great.
If you dont care about extra speed and ride bad roads, i'd consider selling the speeder, because comfort really does matter. I sold my giant propel for that very reason.
What crankset and calipers are you using? they both look cool.

Geo indeed looks vastly different but my position is almost identical between the two bikes. Within a couple of mm.
I have no doubts that Rose buys their frames in the far east but they are not your regular "just paint the OEM frame" kind of brand. Most of their bike have really unique features and I'm pretty sure that at a very least they have R&D in Germany and they design their own frames
Crankset is Leese, here's the link: https://vi.aliexpress.com/item/1005008541602018.html I'm very happy with it, I paid something like 150$ with the spider during one of the sales. I initially received the spider that was a little wobbly but the seller have sent me the replacement really quickly and have 0 problems since.
Calipers are ZRace XG. They are definitely better than the original ltwoo and super light (don't remember the exact weight but they are lighter than the dura ace calipers) but I had a hard time bleeding these. None of the adapter from my bleed kit fit the bleed port on these calipers so I had to get creative.

I think my original post turned out as overly negative but just to clarify I really love the bike. I just shared my perspective as someone new to race bikes. I will definitely keep the bike. Thinking about doing head to head tests against the Rose once I get my hands on some powermeter pedals.

For what it's worth, I've been riding my Speeder for about two months now and I don't find it uncomfortable at all (including a recent 205K ride). I'm running 30mm tubeless at 65-70 psi, but it feels like I could go lower. For comparison, in the last 15 years, I have ridden mostly a Dengfu R06, Giant TCR and a CAAD8.

If you only had the Speeder, you wouldn't know that Rose would be so much more comfortable, and you'd probably find the Speeder to be plenty comfortable :)

Yep, that was exactly the case. I was exclusively using speeder as my road bike this season and was completely satisfied with a ride quality but one day I accidently reset my ltwoo derailleurs before the ride and didn't have time to set it up so I took Rose and that was my "holy shit" moment.

I love this bike (only 1000 km ans max ride of 100 km) with 28 mm tire which measure 30 mm on my rim. I don't find him uncomfortable but my roads are almost always in good condition.

Even in face wind I enjoy to ride it.

I'd be curious to see how the R55D feels against my Tavelo Arow if they are indeed from the same factory.

The Arow isn't harsh at all especially with 30c tubeless tires. But I also have high tolerance for stiff bikes.

Okay, so it's time to say a few words about my plan for this frameset.

I am currently riding my first road bike Bianchi Sprint size 53 on 105 Di2, which I bought in July 2024 - due to the huge saddle to bar drop (125mm) and the search for comfort, I plan to sell it and spend the entire amount on this project.

I have pre-ordered a Speeder SC-R55D frame in size 510 in white gloss and 50/60mm speeder wheels with wide rims.

I plan to install Ultegra Di2 groupset on the bike, but I'm still considering changing the original crankset to spider powermeter (Sigeyi/XCADEY), carbon cranks (Elilee?) and Pass Quest/Stone chainrings.

Below I paste the project table, my current bike and the speeder rim profile.

EDIT: As it is my first build im open for any suggestions and tips!

Rose x lite looks quite similar.
My friend has one, he'll measure the dimensions and I'll compare it to my speeder

Coming back with the measurements. Rose Xlite seatpost is 32.6x22.6mm and speeder has 34x22mm so close but not quite the same

Have you gotten this built yet?! Excited to see it in white, cause that's what I'd do also

All parts ordered - just waiting for shipping  :)

Frame should be sent in the end of July.

Idk about this frame. In a size 58 for me, the wheelbase is 1020. That seems crazy long and not ideal for crit racing...

I got the 480, which is a little smaller than I am used to and installed a 130 mm stem. Its wheel base is 7 cm shorter than my previous bike, and it is just as very reactive. I can't notice the difference at all. The Speeder responds super quickly, and it's been perfectly fine for crits.

Elaborating on this would be valuable for the audience.
