It's just shy of 4mm clearance to the chain stay.
46T will fit fine, 48T might just fit into the space made for the chainring, probably with tight clearance.

Thanks Florian. I also assume the BB needed with the wide E1 cranks was just an internal T47?

Cheers

ZEN Carbon 80/80mm Wheelset – 1,509.6g Actual Weight, with Potential Builds Down to 1,379g
l rear, I thought that was a pretty respectable result.

Actual wheelset specifications:

* Rims: 80mm front / 80mm rear
* Internal width: 24mm
* Maximum external width: 34.08mm
* Rim construction: Lightweight layup, approximately 580g per rim 135kg Load limitation
* Hooked, tubeless-ready
* UD paint-free matte finish
* Drainage holes and spoke access holes in the rim bed
* Spokes: 4mm carbon, 20 front / 20 rear
* Hidden nipples
* Hubs: H-Works SR270 Silver
* Hub weight: 279g ±5g per set
* 36T ratchet system
* Steel bearings
* Centre Lock disc interface
* SRAM XDR freehub

The customer specifically wanted a wider internal rim for their TT setup and preferred the more substantial rim construction rather than chasing the absolute lowest weight.

We also offers a Super Ultralight rim construction at approximately 540g per rim, with a 100-110kg system weight limit.

Using those rims with the lighter ZC215RC hubset, 3.2mm carbon spokes and hidden nipples, the estimated complete wheelset weights are:

Configuration Estimated weight
80/80mm 1,379g
75/80mm 1,359g
75/75mm 1,339g

The 80/80mm Super Ultralight configuration would potentially save around 130g.

Is a 16 spoke option possible? At least for the front.


Cheers

Took my G028 out for the first "real" ride yesterday.
My other two bikes are from Scott, an Addict RC from 2020 and an Addict Gravel from 2025. Both are much more race-oriented with a more aggressive geometry.
The G028 rides like a charm, very smooth, very solid, still quite fast. It is slower while cornering, but that is very expected with the different geometry. It was pure street / tarmac yesterday, so I couldn't really test any offroad capabilities. Sure, the 2.2" Dubnitals (Trail casing, not Race casing) aren't that fast on the Road (compared to my beloved GP5000 AS TR), but more than ridable.

I don't love the head tube / top tube intersection, looks kinda goofy. Not sure why they designed it like that, I do prefer the look from the Mondince FM376. I also do prefer the seat stay / seat tube junction of the FM376, but it's fine. I do prefer the downtube bottle cage mounts on the SPCycle, they're way too high on the FM376 in my opinion.

My hacked SRAM crankset × Shimano Derailleur drivetrain runs great, no issues here. I might upgrade to SRAM XPLR down the line, but so far I'm very happy with this setup.

The Rpantahi cockpit is really good, super clean looking, nice 360mm width, absolutely reliable. I just ordered another one for my Addict RC.

If you have any questions about the frame / bike, let me know!

Sweet build! Couple questions..

Is that the road or wide E1 force crank? What's the max size front chainring that you believe can fit? Also, is that the od2 Rpantahi cockpit? If so, did you just use a shim?

Cheers

Greetings,

Since the geometry is near identical, is there any specific reason to choose the SP G028, MEINIER-GRL15, or Mondice FM-376? I assume if value is most important, the Meinier is the top choice.

Cheers

Looks nice but why did they add mounting holes on the fork of an aero gravel bike. Anyone know the availability?

Got the frame in and overall I'm very impressed. Quality looks great and weight was right at 650 for the frame with dropout and fork was 310 uncut.

I'm doing the maths and even with some heavier wheels, I will be close to sub 5kg. The picture is with a cut fork, headset, spacers, stem, and handlebar at 1220g.

What's a good USD price for the 280g version? Cheers

I decided to convert mine more for climbing. It's at 6.6kg fully with pedals and power meter. Now I'm wondering if I should have went with the lightweight model with internal cabling! 

Looks proper!

Considering mine will be a XXS, I'm hoping the difference is around 300-400 grams less for the fork and frame compared to your version. Unfortunately I haven't had much luck with claimed and actual weight when dealing with AliExpress.

I'm not going all in but I will be very selective on the parts I'm using. I should be under 6kg race ready but would love to be well under that considering this build will be a 1x and the rider is only 21kg.

Apparently mine shipped out today! Let's see how long it takes to arrive.

Max chainring 52? Lame.

Lol, I bought the exact same frame recently, for a frame swap. Really happy with it!

Haven't taken any good photos yet, but I'll post here when I do.

Nice build btw!

Nice! Did you weigh the frame and fork?

Excellent build and thanks for the review. I actually just ordered the XXS 580g version for my son a few days ago. I paid a few hundred more but if the weight is close to what's advertised I will be happy.

Quote from: gbrnole on July 29, 2026, 03:39:01 PM
the weight is unpainted with all the attachments removed but those frames are shockingly light, the fork is a featherweight too. I pondered grabbing one before i got the SL8. if, or more appropriately when, your kid drops me on this new rig, i'm gonna be hella embarrassed and have to get an unrestricted e-bike!

Haha.. and yeah even if it's 650g with paint, that will still shave 600+ grams from his current frame. I will go all in and see how close to 5kg I can get.

His current setup is around 6.8kg

To circle back on this post, I went ahead and gambled on the Microck aka Bigrock Aethos Clone in a size XXS 45. The seat tube is listed at 400mm although it appears I could maybe take upwards of another CM or two to get it even lower. It's also listed at 580g which I find hard to believe. I will be sure to follow up once it's received.

I was on the same point a few weeks ago.

I wanted to build a bike for my 8 year old son. The Bigrock Sothea is pretty much the smallest frame you can get, but I didn´t want to spend that much money.
Therefore I ended up with a R088 in size 44.
Stem 35mm 
140mm crank
The saddle height in the picture is not final. I had to cut the seatpost and slide it in as far as possible.

Since he´s racing, the gears are limited and I went for a 1x11 Shimano 105.

Final weight including everything is 6,8kg

Awesome setup and i'm sure little man is flying on that!
