Please add option for external cable routing. I beg you!
Will there be a rider weight limit for this frame?
If I had 1 regret about buying my SP-M06 it's that it has integrated headset cablee routing, next winter I'm either YOLO drilling cable passthroughs in the side of the frame or buying a new frame to get rid of them...
Cable ports as an additional option for cable routing (instead of headset routing) would be a good compromise if external routing isn't possible.
I won't name specific other brands. But... I've recently worked with another, fairly well-regarded OEM manufacturer, to add side cable ports on their full-suspension frame that don't have them by default. Whether they execute correctly on our final agreed-on spec (READ: not just *MY* spec), we'll see when I receive my frame.
The whole press fit BB and headset cable routing is a complete drag. I'm not sure if they even want to sell mountain bikes anymore.
For this reason (plus the obvious cost reason) I've skipped all the big western brands now.
Some Chinese frame manufacturers are willing to accommodate, and even accept custom paint jobs, so it's probably worth asking.

I'm very interested in buying this frame, you refer availability in mid-June, can you confirm this estimate and also inform about its price???
Seat tube in size S looks too long for me, and a seat tube has bottle cage mounts. I would buy this frame for my wife, if it could fit a long dropper post.
Just got word from Spcycle over email, where they informed that this frame is currently undergoing ISO 4210 testing. If it passes the test successfully, it will proceed to mass production. The estimated price is 550-580 USD, including shipping cost...
RiP, did you ask if there are cable ports on the left side of the frame and, if not, if they could be added?

No, I didn't ask any of those questions. Even if those requests are possible, I guess they'll impact production/delivery times... :-\
This frame is set to be available to order from July 20th... 8)
July 23rd and still not listed on their website.
Yes, I already inquired them about this over email a couple of days ago, but got no answer yet... :(
And 1 week passed, still no reply to my email... :(

Have you tried to message them via the official "SPcycle Store" on Aliexpress? They have answered my questions in the very recent past very quickly.

Got a reply over at Aliexpress, in short time, as you suggested:
QuoteM038 has been completed for mass production. We will list it as soon as possible.
Here we go! Finally got word over email, they say they'll list this frame on their website next week, as they've now finalized mass production... 8)
They also shared the weight for all the frame sizes:
QuoteThe following is the weight of the unpainted frame
Size S 820g
Size M 845g
Size L 870g
Oh yeah! Now I'm waiting for a price ;)

The frame price should be around these Numbers, shipping included.
To the US, I have never purchased, or seen listed, a SPcycle frame listed that doesn't charge $170+- in shipping charges. Frames with fork, typically have been priced between $500 and $600, and frames without forks priced between $400 and $500.
Just saying...

I asked for the price with tax free shipping to Europe and that was the figure they told me. Also, according to their website, all their frame (+fork where it applies) prices include tax free shipping to Europe and USA...

Lucky for buyers in Europe! These days... Like our gov'ment, our corporations, our shipping companies, our businesses, everyone is trying to suck every last penny they can from consumers.
PS, since the price you quoted was in USD, I figured you were a US based customer.
I bought an spCycle M868 frame 2 months ago and got free shipping from AliExpress.

Great! Can you list it at AliExpress too? Thanks!
And, order placed at AliExpress... 8)
Hi,
I also ordered via AliX, a nice light pink glossy L frame I will build up with as a gravel/commuter. 65mm deep and 40 wide rims with a dynamo. As a fork I will use a Winow 410 atc rigid carbon fork for 60mm max tires.
Not sure how much saddle setback I need. It will be a sta of around 79 degree for my saddle height. Horizontal distance from saddle to handlebar is 770mm. On my roadbike position I have 790 but I sit kinda long and low.
Hope I can share my build journey.
I have some doubts in ordering this frame as it has a very long reach. I want it for my kid next race bike in size S looks too big. Too bad there's no XS size for someone around 150 cm height.
There's no free shipping to USA this time.

Hi! Are there any plans for a similar version (66 degree head angle) which is not that super light and thus more durable? I am honestly a bit scared by the weight and would very much prefer a more trustworthy version with approx 1100g. :)

Yes, we will make a regular version. Weight about 1000g

I quite like the superlight version as is, except for the cable routing through the headset, which for me is a deal breaker.
Are there any chances you make a version with regular cable routing outside of the headset? Thanks!
My frame got delivered today. Crazy light, and sadly the mounting of the rear brake is poorly finished. BB area kinda clean. But all in all seems fine. Looking forward to my spectacular gravel build.

How is your build going ? any more comments on the frame?
I was sick last week and a lot to do at work. Sadly not much happened last weekend. I painted the fork dark red... or tried to. I tried putting the crankset and it fits. So bottom bracket was going in smooth and it's nicely faced and no paint overspray. Q factor if 153 does fit. It is very narrow and chainring (42t) has 2mm of space left I assume and crankarms maybe 5mm. I want to run a mechanical groupset, but sadly where the rear triangle is glued the frame gets to narrow to push anything wider than the cable routing tool through. I am wondering if anything besides carefully sanding it with the cable routing tool will work. Because on the other side was enough space for the brake line. And it seems to be symmetrical.
Next update on my bike build. Installed the cable routing and brakes and fork and stuff. Picture attached. Crankset fits very tight and sadly my chainring is a little bit like a 8. but what did I expect from a 20 euro part ;) guess it will still work. I assume it's easily possible to run it with a 44 or maybe even 46t chainring, Q factor very small in this Evodid crankset as I mentioned before. I am very happy with the look.
Next thing is to build the dynamo hub front wheel (12x100) and rear wheel (boost) and then after adjusting the brakes and shifting, I am done :)

Looking good!! Keep us posted!
It didn't went that smooth with building the wheels. Was my first time and took a lot of time... but I finished the build and broke the shifting already when adjusting. The lever broke... guess friction was too high with cable routing... I will have to take a look into it the next days. But I took a spin around the block. With this geometry I need to find the right saddle position and the bars are very wide. But looks great and feels super agile.
