My Miracle FS822 arrived this week. I'm excited - it has taken me 6 months to choose, order, cancel, re-choose and re-order the frame for this next build! Interested to know if anyone is using or considering this frame - there's very little about them on the forum here.

It is size L of this frame painted gloss black: http://mira-factory.com/Product/detail/id/43.html.

Frame was chosen because Miracle have been around for a long time, good geometry, good price, good communication. It's also nice to try something a little different. I think this new breed of 120mm cross country frames is one of the most interesting MTB developments at the moment, and I can't wait to try it out.

This is my third Chinese frame build. Others are Airwolf YFM026 hardtail (2.5 years old, no problems); and a Carbonda 1001 (my son's. 18 months old. Gets hammered. Parts frequently break but no problems with frame).

There are a few reasons for this build:
1. A reward to myself for hitting 3.5w/kg when training for this season (although racing didn't happen because of life!).
2. To take over from my old Kona Hei Hei race bike that I really miss!
3. Something that I can use on less extreme trails, but that can handle them when needed. This should be great for marathon races in BC, Canada and for all day rides up in the alpine!
4. To potentially take over from the Airwolf, which I will either sell or convert to singlespeed and fully rigid.
5. I love selecting and building these bikes.

I'm not quite ready to build the FS822 yet - it arrived quicker than expected! This week I have unpacked it, designed decals and ordered wrap.

Build will use:
- Fox 34 Performance Elite 120. Removed from Airwolf and fully serviced with new decals from Slik
- Fox Float SL
- Dartmoor Tomcat rims. DT240 front hub and Shimano XTR rear with Sapim Laser spokes. Not yet built
- Bontrager Raceshop Limited carbon bar/stem combo, TransX 150mm dropper
- Magura MT5s
- Drivetrain from the Airwolf: Deore 12sp with XT shifter and X0 carbon crank / chinese power meter.

Impressions so far:
- Seller was Sally. She has been excellent at answering my detailed and sometimes stupid questions and always responded quickly on Whatsapp. Recommended.
- Frame was in stock. Paint took just over a week. Frame was shipped immediately by UPS and arrived in Canada in 5 days. Frame very well packed.
- I have not checked frame bearings etc yet but first impressions are that this is my best frame yet. Very clean inside the frame. Paint is excellent (1 small blemish that has been touched up on ICSG mount). Seatpost fitted very smoothly.

I have high hopes for this frame from on experience so far. I'll update the thread as I progress and if / when I run into any problems.

Poor pics taken so far are attached!

I know Eddie from Haideli has posted about the FM-XC029 (https://chinertown.com/index.php/topic,3770.msg37810.html#msg37810) but I can find very little else about it.

- Has anyone built one? Experiences?
- Is it the same frame as from other suppliers? My list of potential XC builds suggests not but I am likely wrong!

I ask because it looks like a good value option for my 2023 cross country marathon build, which I am currently obsessing over.

I am intrigued by this bike after seeing it in XC World Cups: https://thoemus.ch/bikes/lightrider-wc-2020/

It looks like it could so easily be a catalog frame. Does anyone know? Who makes it?

What I’m aiming for
I have been eyeing up unbranded frames from China for about 20 years. I really missed a 2013 Kona Hei Hei XC bike that I had sold and liked the idea of a hardtail to replace it. I wanted something light but capable, understanding that a 100mm fork that I found on sale sets something of a limit. I wanted to build it on a budget with a focus on function and value rather than bling and ultra-light weight.

I live on Vancouver’s North Shore which has a reputation for pretty gnarly trails, but wanted something that would be a blast on the less extreme trails that often get forgotten. That said, I know this bike will end up on some of the harder trails from time to time (see below!).

The frame, bar and seatpost were bought through the Airwolf store on Aliexpress. Their communication was excellent. It took about 6 weeks to arrive, but would have been quicker if I hadn’t had it painted. This is one of the few frames I could find with modern XC geo – notably reach, head and seat angles and BOOST. It was extremely well packaged with no damage. The only fault I could find in the finish is some rough edges in the head tube. I did not see any of the issues that some have reported about poor dropouts or fork crown hitting downtube (this is a large frame).

The crank was ordered from Zrace on Aliexpress. Their communication is OK, and I'm really pleased with them so far.

Other parts I either already owned, bought second hand or found on Ebay. The build went very smoothly. Any issues I had were definitely my error, not with the frame. The internal routing for the rear brake was a lot of work, but no harder than it would be on any other frame and it looks good once done! One thing to note: the other ports on this frame are designed to run inner cable only in the frame, as opposed to a full length of outer. This means I’ll need to do some fiddling if I want to fit a dropper post.

Initial impressions
This thing is light! The frame comes in at about 1150g with hanger, thru-axle and seat collar. Built up, the bike is 19.6lbs without crank or pedals, so I’m expecting 22-23lbs once the new crank arrives. I’m really pleased with how it looks with matte black components and a bright colour on the frame. No-one really seems to notice my little stickers, which is fine by me. I know what they mean (UK riders may be familiar with the Mint Sauce font and quotes!).

Even with the 40mm stem, it’s quite long (size large and I am 178cm tall). The steering is really quick. The brakes didn’t work (not bed in). The whole thing feels ‘tight’.

First ride
I was in a rush. I needed to get up the mountain by 6pm and I didn’t get home from work until 5.15. I stuffed my backpack with shakedown test musts like a shock pump and multitool and sped out the door.
Coming from a big-ish trail bike the Airwolf immediately felt weird, with lightning quick steering and very fast acceleration. The beginning of the ride was mostly on road to get up the mountain as fast as possible, but the little sections of singletrack gave me an inkling of how this was going to be: playful and fast (and too long).

You’ll be pleased to know I made it to the trail head on time. Everyone was interested in the new bike (most of them knew it was in the works), and there were plenty of jokes about me emerging from the forest with shards of carbon fibre up my arse. I had promised myself that I would not go straight into the gnar with this bike, but the group was heading up to a black-rated trail (7th Secret). I figured I’d give it a go and tweak the bike as I went / walk if necessary.

The ride to the top confirmed what I’d found on that initial climb: a bike that is quick to accelerate and encourages you to fast.

The beginning of the ride down was a different matter. The top of 7th Secret is quite steep, rocky and rooty. It was also greasy that day. I had not had a chance to bed the brakes in and I am used to a 160/150mm bike with a 65 degree head angle so I was pleased that I managed to drop in to the trail without snapping me or the bike. After about 2 minutes I put the seat post in my bag because I couldn’t drop the seat enough. If I’m going to keep riding trails like this, I’d need a dropper. As the brakes started to bed in, I started to appreciate the quick steering on the tight switchbacks.

As 7th Secret merges into the lower trails, things start to mellow out. This is where I realized the bike is exactly what I was hoping for. This is no 90s alloy hardtail throwback – there is quite a bit of flex in the frame and it’s pretty comfortable for a hardtail. That quick acceleration is addictive coming out of corners! I’m sure the fastish rolling tires helped here, and it’ll be interesting to experiment with North Shore go-to Maxxis DHF and DHRs at some point.

From the first ride I learned a few things. First, I really like this bike. It makes the ‘easy’ trails a hell of a lot of fun, which is just what I was hoping for. I would far rather have this than a gravel bike, and it’s probably not much slower on dirt road.
 
Secondly, a little faith in the established Chinese manufacturers is probably warranted. I really hope this frame lasts and becomes great value. I don’t think it will take long for me to trust it.
Thirdly… rushing out for a ride down ‘big’ trails on a bike that isn’t really set up yet is probably not a great idea. Go and bed the brakes in, tighten any loose bolts and realize you need a dropper before you go out in public.

One month in
I would highly recommend anyone looking at this frame to be careful on sizing. It's long. I have got the seat nearly all the way forward and it's fine now. Just after I got the YFM026 working a friend of mine bought a gravel bike and we went for a long but gentle ride. I loved it - fast, comfortable and light but much more capable than a gravel bike.

I have some fast singletrack trails close to my house and I absolutely love this bike there. So much fun!

A couple of tweaks to come! The bars are too wide. I'll cut them down to about 760mm. I have a seatpost shim on the way so I can install a dropper. A clip for one of the cable port covers has snapped and I also want some more to run full length inner cables for the gears and dropper. Airwolf have been really helpful and, after a bit of a language barrier, I think are sending some.

Pics
Lastly… pics! No post would be complete without pics of the bella machina.
