Chinese Carbon MTB > 29er
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.
acedeuce802:
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.

Hi. I’ve been lurking for a bit. Starting to do a little posting now.
Ar26:
Hello, I come from a planet quite far from your earth. Sometimes I come back to my second home which is located near “the hell of the North”. Expression which designates “Paris-Roubaix”. Well, I'll leave you, I'm going back to my planet. There, changing gears on the bikes is done mentally, what progress.

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!
