Re: Welcome to Chinertown - Introduce Yourself! Carbonda FM909 will be available with 120mm rear linkage soon.  Should meet all your criteria except ISCG tabs, and will be lighter than the FM1001.  66deg HTA with 120mm fork, steep STA but not too crazy, I think it's 76deg with 120mm fork.

Re: Miracle / MIRA FS822 Mini update. I picked up the final part (dropper) last night. I was hoping to use the dropper from my Airwolf hardtail but it is stuck - my first time as a victim of alloy post corroding in a carbon frame!

Order of little bits (BB; centerlock / 6 bolt adapters) from ZTTO arrived in less than a week.

Decals and wrap added to frame and cables/ hoses are routed.

Shock is fitted. The hardware was a bit of work. The shock reducers are listed as 8*22mm but the front one did not fit - I filed it down to ~21.7mm and it's in. The BB is fitted - no issues at all with the threads. As I get to know the frame, I am impressed with the quality.

I'm aiming to build the bike this week, and hope to have a 'shakedown' and first proper pics and report this weekend. I'm excited to finally ride it and do the 'big reveal'!

Re: Welcome to Chinertown - Introduce Yourself!
Hello!
I joined after lurking for a few days reading about all the different companies making open mold frames.

Im interested in something fairly specific.  Currently have a Trek Top Fuel 7 (aluminum) and its fairly heavy (by my standards).  I started riding in my youth around 30 years ago, and by the late 90s was really into XC racing on a hardtail that weighed around 21 lbs.  I pretty much stopped riding for 20 years and picked up again in 2022 and wasnt in very good shape.  I got the Trek and got back to work training and getting faster.  It of course feels pretty heavy but ive put carbon rims on it and dropped some weight off it in a few places.  As I train for races I want to reward myself for the work im doing and so im looking for a frame with similar geometry - 120mm travel but with the right shock size to get a remote lockout on it (the Trek uses 185x50 shock which isnt available from fox or RS with a lockout).  Ive compared all the major brands, I do like transition spur and fezzari signal peak, with the fezzari frame being the cheaper option.  Then I started looking at open mold frames.

Heres what im looking for:
120mm travel (might consider 110-115) because outside of racing i do ride some good trails
shock size that allows for remote lockout (cable routing for remote lockout a plus)
BSA bottom bracket (preferred over press fit - Ive never had a pressfit but it sounds like a nightmare on cheap frames with creaking etc.)
66-67 deg head angle - again outside of racing I do some aggressive trail riding

Bonus points for being made of better materials (blend of T800 and T1000 better than T700?)
Bonus points for having ISCG-05 mounts (although not a dealbreaker because I dont currently use them)
160mm disc size is fine

Here is a list of some that seem to meet my needs:
Miracle FS822 - seems new, Head angle a little steep but seems to be due to short fork length - my current favorite no idea of price or color options yet
Lexon Flyer (ebay) seems like the same as the miracle (they use a more realistic fork length and get 66.4 head angle) but ebay only has 2 color schemes and I dont want the decals.
SP cycle SPM861 - not sure about the cable routing in the headset or if it has routing for the remote lockout (doesnt look like it)
Workswell WCB-M-364 - not much info on it - looks like you can spec a BSA bb but its also a vertical shock 185x55
BXT-MTB-147 (ebay) - looks nice except 69 deg head angle - I guess I could use an offset headset and slacken it a little but thats more work.
Carbonda FM1001 - more travel than I need unless I use 185x50 which put me back to no remote lockout, I suppose its possible to go longer travel with a lockout (185x55)

Am I missing any companies?  Winowsports and DIYcarbonbikes are pressfit BB.  Airwolf YFM059 doesnt have enough travel for my taste.

Congratulations on getting back into riding. It's the best way to keep physically and mentally fit!

You are looking for exactly the same things as me. I went for a Miracle FS822 and am building it at the moment. There's a thread on the 29er page. It ticks all of your boxes except shock stroke (which you may be able to change, depening on your shock. Fox DPS easy. Rockshox not so much). The short fork on the fs822 geo chart is an error - I think it says 505 axle-to-crown but should say 530. Keep an eye on my thread and learn from whatever I bump into!

Re: Carbonda FM909
Is the only difference the linkage?  You use the same shock length and stroke?  Hopefully it would be OK with a 120mm fork (im fine with it slackening the HA a little I just wouldnt want to weaken the frame from the extra fork length)
I also replaced the fork SID SL 100mm with a SID Ultimate 35.
I use the same shock SIDluxe Ultimate 165x42,5mm.
But i removed the green 2,5mm spacer (stroke reducer).

The linkage only pushes the rear wheel further into rebound, raising the BB and giving more clearance from the seat stay bridge to seat tube. If you use the same shock, you'll have the same travel, you'll just ride higher. You'll need a 165x45mm (or remove the travel reducer during a rebuild from a 40 or 42.5) to the take advantage of the travel. A lot of people use 120mm forks on these, and with the longer linkage raising the rear end, a 120mm fork is preferred to keep geometry in check.

Re: Miracle / MIRA FS822 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).
