Chinese Santa Cruz/AM831

[RDY]

Thanks for your care and wishes, yeah, now the virus have been controlled, the factory being produced again.

And all mountain AM831 frame rear shock is 210*55mm. totally right.

Fork travel and frame travel, both 150mm.

Your website still lists it as 140mm travel frame.

@Eddy
what diameter seatpost does it have?

Comparing the geometry of the hightower vs the tallboy, other than wheelbase (1232mm vs 1211mm) nothing is drastically different, generally a couple of mm or less than half a degree.  Do you think this frame could be run with 120mm travel front and rear to mimic the tallboy?  Love the idea of a SC clone but have no need for 140 or 150 travel where I'm at.

You could probably do something like 130/130ish by running a 210x50 shock.  Running a different eye to eye shock is purely speculative and could mess stuff up. If you go shorter than 150mm out front you're going to mess with the numbers too though. Steepen up HTA and STA, lower bottom bracket as well as a couple other things. The rear shock will not change anything really.


I'm guessing that this bike is going to be closer to 150mm out back if it is paired with a 210x55 shock, which is about what actual hightower owners experience when they long shock their bikes.


You can get service centers to swap between 210x55 and 210x52.5. It's not too tough and the hightower likes a custom tune anyway over what most aftermarket shocks come with so don't stress about buying the wrong shock.

with a 210x55 shock it should deliver about 147/148mm of travel...I will pair with a 160 fork.
I agree with the idea of a short travel trail bike in the 130mm range.

I have been looking for that for quite some time but it just seems to be missing from the market.

this is the "do it all bike" imho, especially in 29" wheels; if not an enduro racer, 130mm pedal really well, go everywhere with a touch of playfulness and an active rider.
By the way, I have everything in house to build it on the enduro side, so that's the way I'll go, at least until summer; in July I'll race Enduro2  in french Alps (3 days of race with a team mate)...obviously if Europe sort out of coronavirus! Here in Italy from today we're allowed to move from home only to buy food or go to work (weekends every activity will close)

I waiting on delivery of a TanTan FM10, the newest revision of the FM08.  That will do 135mm with a 200x50 shock.  The geometry is not quite as new-school as the hightower cone, but its still plenty aggressive.  I'm planning on trying both to see which I prefer.

I'm very interested in participating in the group purchase as well. Are there any updates on this?

I'm also eyeing the FM10 and the Hightower clone.  Please keep us updated on the FM10  .

Well, I guess we can start by getting a count of who's interested. Maybe we should start a separate thread and keep this one on topic: http://chinertown.com/index.php?topic=2891.new#new

Yes, now we need to collect the information of how many people want to buy the FM-AM831 frame, then i can quote the bulk price sooner, thanks.

@chetosmachine

The diameter of the seatpost is 31.6mm.

[scourge]

Eddy, are the seat tube lengths listed on the website correct? Everything else seems to exactly match up with the Santa Cruz Hightower except this. If they are correct I would go large, but if they are incorrect and actually match Santa Cruz, I would think about XL.

[ReverendRockRazor]

 Anybody know the weight?
