Mine came with an axle as well. I believe it's a 12mm thread pitch but I can put calipers on it if you're looking to buy a spare ahead of your frame arriving.

Hello,

I consider purchasing FM10 as well.
I am 184cm tall with 87cm leg length. I am considering 21'' frame.
In the internet each calculator is giving different result.

Please advice.
   

You might check out this article on bike sizing: https://www.leelikesbikes.com/rad-bike-setup.html

Per formula, your "ideal" rider area distance (to enable your body to efficiently exert force on the bike) is 822.48cm
The RAD for the 21" frame calculated from reach and stack height is 798, meaning that with a small spacer and stem, you should be on the money for bike to body size, though without much wiggle room.

The 19" frame comes in at 775.63mm, a little smaller so with a few spacers and a stem you'll be right on, with the flexibility to change your size around with stem and bars rather than buying a different frame. A touch lighter on the climb as well.

Both will fit, the 19" should have more control and feel a bit more playful, the 21" should be feel more planted and stable at speed.

What type of terrain do you ride most often?

I switched out the fovno cranks for a set of ZRace Blade cranks (with the steel spindle).  Two reasons, one, the BB is low on this bike running 27.5s so I need to find a way to reduce pedal strike. So far so good. The other is the Fovno aluminum spindle gave me a scare early on, and although I was able to solve the problem with those cranks, I'd rather have some extra durability under my feet for the the (hopefully small but unmeasured) weight penalty.

That's good to hear! I've been eyeing these as well . Just curious what kind of riding you're doing with them. Would you say they'd be good for AM or Enduro?

I don't ride that aggressively (yet) as I'm out on the east coast USA. I'm moving to Calgary soon so I expect to test them out on some longer rides/longer sustained descents. They had no issue on a trip to Colorado for some half day rides with ~1000ft elevation. I don't expect they're the best, but I'll update if they have any issues.

I’m also curious how these shimano clones turned out??

They are awesome! A bit challenging to bleed, but they've been flawless and 0 maintenance for a year or so. I bought another set for another build.

The crank bolts on the fonvo cranks stripped for me so i had to cut through the axle, metal used was far too soft

Good to know. I may go with the zrace blade as a replacement, the one with the steel spindle.

Did you try the DUB version or the 24mm one ?

The 24mm version

I've had a lot of questions about the Dairs wheels, so I wanted to post here that... they never showed up :( I'm still trying to figure out what went wrong with that.

On the other hand, the light bicycle AM733s I have are fantastic, and the bitex hubs are the best I've ever had on a bike (but I've never had much top shelf gear, so this whole bike is really a massive upgrade for me).

The Fovno cranks - I did have trouble with them, but I think there may have been some 'operator error' on those, so I'm not convinced the parts are shit, it's possible the shit's on me for that one. I've gotten my hands on a new crank bolt and am going to do some more testing before I call them a waste of money. Hopefully I'll have some updates in the spring.

Have had a blast on the bike though! I think that going with the cheap frame and cheap components all around except for wheels and suspension was the right call, at least for me.

Can anyone confirm if a 185x55 trunnion Rockshox will fit and not cause problems?

185x55 trunnion Rockshox will NOT fit.

Emu - here is a pic of the rear tire. I think you could comfortably do a 2.8, a 3.0 might be pushing it but depending on your rim, you might be able to squeeze it in. These pics are with a Maxxis DHR2 2.6 (the wide tire version) on a 40mm rim (33.6mm ID). The rim is a light bicycle AM733 if you want to hunt down more specs.

Nice price on that shock!! I think you'll like the frame, even with some of the issues we're seeing here. I got the 27.5 version of the frame.

Also - just to note - The crank bolt on the Fovno Phantom cranks sheared off mid ride on me last week. It's thin, cheap metal, so for the record, it's not very durable. A few pedal strikes can weaken it enough to cause issue, and the crank arm just let go while I was pedaling uphill. Thankfully not a disaster that caused injury, but I would be careful if you go that route. There's a reason they are so light...

I was able to fix the derailleur and the chainline! I took some things apart and realized 1: I forgot to put the spacer in behind the cassette  :o so that was an easy fix. 2. I have the fovno cranks running a spider adapter to a 104bcd 34t oval chainring. Flipping the chainring to the inside of that stack closer to the frame (rather than on the outside nearer to the pedals) gives an excellent chainline putting me centered on the center cog in the rear cassette. I'll take some pictures of how it's rigged up if that would be helpful to you.

If you had cranks with a gxp chainring and didn't use the adapter, it would put the chain line to far outboard and it would cross/bend pretty hard to reach the big cogs.

I went with the boost frame, and the SRide 12speed derailler with an 11-50t cassette. Just to be clear I can confirm I can now access all the gears smoothly. And that makes me happy.

Note: the rear axle that comes with the bike is trash, and sheared on my when I was installing the rear wheel for the second time. Any old rear axle is better than that one.

The one hiccup I'm having is that the derailleur is seated too far away from the sprocket to get the 12th gear. With the low stop all the way out, the derailleur can't reach the 12th gear, so I'm riding 1x11 at the moment. I'm looking into whether that's an issue with the hanger, or if there's something else going on that I can adjust. If anyone has any experience repositioning derailleurs, that would be super helpful - though I'll see what I can find.

Alright - major update after a long silence. The bike is together, and absolutely rips. I'm really happy with it.

I took my time on assembly, and greased, threadlocked, and torqued things to spec. I had one small creak around the seatpost, but re-torquing the seatpost clamp seems to have solved that issue.

I'm out in Colorado at the moment, and I've so far completed a 12mi ~2000ft elevation ride, and a 10.5mi ~1000 ft ride. Mostly singletrack, loose over hard, 1-2ft drops, some rock surfing, and generally smooth climbs with mild technical sections.

I've also been testing the bike around the property out here, with some dirt jumps we put together (small) to test the flex and dial in the suspension. I'm really quite impressed.

Off to ride some more tomorrow - I'll leave you with a picture of the steed.
