It is almost exactly a year since I built this. Not very well known here. I like it a lot: https://chinertown.com/index.php/topic,4524.0.html

I found spcycle difficult to deal with. If you want a no risk option, look at Carbonda - they are excellent.

There was more interest in inexpensive Chinese carbon frames during COVID when demand and prices for bikes were so high. Since the bike market crashed, and there are many more discounted new and used options, the cost / benefit ratio of these types of frames have dwindled or disappeared. If you realistically budget solid, proven parts, the savings over a currently discounted or used established brand are often modest at best.

Many people have unrealistic expectations about inexpensive Chinese carbon full suspension "all mountain" bike frames. For sure, they can be an adventure to assemble and fun to ride, but frustrating problems and surprises are probably more common than people expect. Fork crowns that hit the frame, suspension that gets stuck in the compressed position, or even rear triangles that can't be ridden as designed are examples. Consider what that says about the design and testing culture these frames come from. Unsurprisingly, kinematics and details like weather sealing are often inferior to name brands even when the frame is a "copy" of a well-known branded frame.

In my opinion, open mold, inexpensive Chinese frames are great for people who like a challenge and like solving problems. I don't think a 10kg 150/150mm all mountain bike is realistic.

^^ This.
- post-pandemic I feel like these frames are a great project but the interest has died down, especially as there are so many deals elsewhere. I love them, but they're not for everyone. This is probably why you're not seeing much about the FM830.
- The Carbonda fm1002 is tough to beat. It is well proven that it can take a hammering and rides very well. Worth the small weight penalty, in my opinion... but you may find the same catalogue frame as a complete bike on discount elsewhere
- If you want a light, good value 150 / 150 bike you might find something like a 2nd hand previous generation Scott Genius a good option. 10kg sounds too light for a 150mm bike though

I am happy with my Miracle FS822. Thread here: https://chinertown.com/index.php?topic=4524.0

It does not have room for 2 water bottles. 75 degree ish seat and 67.5 ish head angle, but i'm running a slightly longer fork. top tube is 628 on a large, so 2mm from your request!

Based on reviews here and my own experience, I would not buy from SPCycle. I have had very good past experience with Carbonda and Airwolf.

Hi,

nice report! I was wondering what made you choose this particular frame, compared to brands with similar offerings that you know already (e.g., Carbonda 936 or 909)?

Cheers

Good question! Mainly geometry, reputation (Mira / Miracle have been around a long time) and... I always like to try something different. We already have a Carbonda in the house (my son's bike) and I've previously had an Airwolf. Both were great, but I wanted to try something else. I am also impatient, and other brands' similar frames were not in stock at the time. The final thing for me was the very good communication over WhatsApp.

The only issue about this frame is it doesn't comes with UDH dropout. We wish that they will come out with an updated rear triangle with UDH dropout feature!

Agreed. At the moment it's not an issue because I'm running Shimano, but the option would be nice.

Just checking with you, how is the correct linkage on your bike now?
Are the 2 linkages for 120(R)/120(F) and 120(R)/140(F)?

in your opinion, how you like the geometry to be improve?


Yes, I have the correct linkage. The 2 linkages are for different shock stroke, but travel is similar at around 120mm with both linkages. It took a while to set up the rear suspension. In the end I used a Shockwiz to get the tune right. It's still very active at the top of its travel (perhaps a shock with a higher compression tune would change this).

Geometry: I think it's fine. It's about right for a modern cross country bike.

One thing I really can't get figured out is wheels. I was going to go for DT 240s but the 350s are much cheaper and the only diference that I can find is ~40g on the wheel set so I'm inclined to go that way. Rims are another thing. I want carbon but the price of the usual suspects seems astronomical. I'm looking at Carbonbeam 30mm internal in AM (325g)... I'm 90kg+ so shouldn't go super light.

It sounds like we take a similar approach - no specific budget but trying to do best we can for what we think is reasonable. I prefer alloy rims, so for my build went for Dartmoor Tomcats because they are ~30mm, ~500g and cheap. I had the same thoughts on hubs as you, and ended up going for a 240 front and got a good deal on xtr rear (Universal Cycles). I built the wheels myself have have a 1700g, wide, strong wheelset for the price of a pretty cheap off-the-shelf wheelset.

An important detail on this frame that anyone considering it needs to know!

In different places, there are 2 different shock sizes listed (184 and 190 eye to eye). I assumed this was an error. Mira confirmed the 190 length and I fitted a 190 shock. It fitted with some fiddling but wasn't right - and topped out as the rocker hit the seat tube.

I checked in with Mira again and they said I should use a 184 shock. After some conversation, it turns out there are 2 different shock linkages available. I had the wrong one. Mira shipped the correct one at no cost. Fitted easily and everything fits properly.

Mira have been really helpful. If you order this frame, make sure you specify which linkage you need. The listing of 2 sizes is not a mistake! Travel with each shock size is the same (ish! 44mm vs 45mm stroke).

There has been some bikes built. Me, my wife and my son has been  upgraded quite a few times. ;D During the pandemic it was easy to sell a used bike so I could build a bike, ride it for a couple of months and sell it for component costs. Now things have changed, its very hard to sell a home built bike so I have  to many bikes and therefore no space for more builds  >:(

But I am looking forward to the new LCFS948 frame, moste likely  I can not resist to build one.



Some great bikes StefanB. I have not built as many bikes as you, but I'm always thinking about the next one! I find researching and building these Chinese frames much more interesting than just buying a mainstream brand.

It looks like you have some beautiful trails and scenery too! Where do you live?

OK. First couple of rides done, so it's time for some first impressions. A reminder that the Miracle FS822 is the same frame as the Lexon Flyer. I am recovering from COVID at the moment so my fitness has all but disappeared. The + side of this is it gives me a good excuse to stop and tweak at every opportunity (rear shock - I am looking at you...)!

First ride... nice pics. But deep down disappointed. A couple of niggles from the build - I didn't like where the bite point on brakes, the chainline wasn't right and... WHAT WAS GOING ON WITH THE SUSPENSION?!  :'(  It was way too soft off the top. It didn't bottom out. It bobbed like mad on the climbs. I was worried that my third Chinese build was going to be the first bad one.

Today, I rode with 2 volume spacers taken out of the shock that has a medium tune (a new Fox Float SL - here it is - https://youtu.be/u-UdqGJoyiY?si=SieY0JbvpUUb7Mzi) and the other niggles fixed. I tweaked it along the way. It is MUCH better.

Summary:
- Don't expect things to be right on the first ride. I knew this already, but I suppose we have to re-learn the same lessons sometimes.

- The whole process of choosing and building one of these frames is awesome. I love these projects!

- Miracle were great to deal with. They struggled with some of the more detailed questions, but they always gave me an answer. They got the measurements wrong for the shock hardware (see above) but... more responsive and knowledgeable than many bike shops. I'm pretty sure measurements are off (and Miracle's don't match Lexon's). I'll try and get around to posting some real world measurements.

- It was shipped and arrived quickly. Faster than I expected - I wasn't ready for it when it arrived.

- It's built into a light-ish bike. It weighs in at about 26.5-27 lbs with pedals and computer. I couldn't go much lighter without spending silly money or compromising the bike's capability. The only significant weight savings I can easily see are in the Brand X dropper and SLX cassette.

- Quality of frame appears good inside. Paint is good. Bearings are good. Everything fitted, and the BB threaded straight in without any problems.

How does it ride?
Now the Fox niggle is sorted... very good! On the ups it's good at getting the power down, especially with the shock in climb mode. In fully open mode it can find grip on some quite loose sections.

My main descent has been down John Deere on Mount Seymour (Vancouver). It wants to rail around corners, drop off (rather than roll) features. It feels quite 'poppy' without the scary feeling you get on old school xc bikes.

There is nothing about it that is life changing or surprising. There is nothing about it that is bad. It just feels like a lively modern bike. It is more nimble than my Scott Genius, but likely not as capable on the steeps. Much of that will be down to set up (e.g. lighter wheels and tires) as well as the frame.

The bike is (I think!) what I set out to build: a capable modern cross country bike that I can race and use for long rides, but that is capable enough to enjoy technical trails. I would love to ride it back-to-back with something like a Transition Spur / Orbea Oiz and also the 120mm Carbonda / Lightcarbons.

That´s great!!! Do you fell like it´s a XC bike or more like a Trail bike?

I don´t think it bobs too much, but I´m using a little bit more sag than usual, like 18% and 2 tokens inside the shock.

I´m really enjoying the bike. Sometimes I feel like the front could be a little more slack and with more travel, but it´s probably my fault for using it in a flow/enduro track.

Not sure yet if the bike is more trail than XC: life has been busy so I've only had a few minutes to test it out and have not been on a proper ride yet. Good to know you are not finding it bobs too much though! I really hope I don't find it needs more travel. Every XC bike I build ends up as a trail bike. I really want to keep this as a capable XC bike  :D

I got a Lexon Flyer.

Using it as a mix of natural trail and some freeride/flow tracks in Brazil.
So far so good, but wondering if I could get more travel on the front.

Using a 120mm Sid Select 35.

ps: I was trying to insert some link for my youtube videos, but don´t know how to make it work here



Our bikes are very similar ;p (http://chinertown.com/index.php/topic,4524.0.html)

How are you finding the ride? I am not sure if the design bobs quite a lot when climbing, or if I just haven't found the correct shock pressure yet. Other than that mine feels good - and fast!

I tried to get an MTB frame from them a couple of years ago and got no response.

I just looked up the Unno thinking with a VPP there's no way it could look similar, but... umm... yes it does. The Unno is absolutely gorgeous!

Took a break today to put last parts on. All done!

Now to set everything up and do a shakedown ride. Then call some friends and plan a big day out!

What do you all think? Is anyone else using this frame?

I still haven't recieved a reply from Sally at Mira from my first enquiry.  How did you go about buying it?

I emailed Sally and she messaged me on Whatsapp almost right away. My initial enquiry was to info@mira-factory.com.
