Re: LCFS 958 build help Hey, surprised you haven't gotten a reply. I'm not sure how much help I'll be as I'm just getting back into bikes but it's not too difficult. You might want to start with a budget to get component selection going in right direction. I've always liked shimano so a 1x12 Deore or SLX group would make for a great first bike. For suspension you could look at lightly used stuff from pinkbike classifieds. And once you get some more specific questions you will probably get more answers. Maybe see if you can find someone on YouTube with the frame and message them to see if they have a parts list?

I don't know what the difference in the frames is, but check out this thread: https://forums.mtbr.com/29er-bikes/light-carbon-fs937-downcountry-29er-build-1101497.html


Good luck and don't be too discouraged by the lack of replies. This place can get slow at times and I get the feeling that many of us are looking at these frames but haven't built one yet so can't give more detailed info but that's just an impression I get from reading here for a while.

...Is there somebody who already tried riding a 20mm stem on a long bike ? Do you think that it is completely stupid ?....

I know this is a bit old, but I saw it mentioned a couple times and there is no such thing as a 20mm stem! Except maybe the bolt on stems that are on double crown DH forks. I believe 35mm is the shortest stem using traditional bars and stem. When you have a 1 1/8" steer tube (28.6mm) and a 31.8mm handlebar diameter, even if they are touching each other with zero stem between them, thats 28.6+31.8=60.4mm รท 2 = 30.2mm center to center. Once you add a little bit of separation and some material for the clamps you're right around 35mm as the shortest possible unless you start notching the handlebar and/or the steerer to essentially get them to partially intersect each other and even then you're only going to knock off a few mm from the total

Anyways, I read that a couple times and the engineer in me couldn't not point it out...

Re: Chinese SC/AM831 Group Buy So they have the molds for all sizes complete?

There has to be a better way as that doesn't make much sense if shipping to different locations with different sizes, colors, etc. They have no problem taking a down payment and with a 60 day lead time, why not give people 30 days to order and once they get down payment it goes into production, then after 30 days or when frames start getting completed they give discount based on orders placed and then everyone pays the remainder of bill for frame, paint, shipping, accessories, discount, etc. It sounded like they knew it was a group buy and each would be different and shipped to different location so they shouldn't have an issue doing something similar to accommodate a group buy.

I'm not sure why chinese companies don't try to be transparent and instead show a low price and then say that's for this one and the one you want is actually this much, or it will be ready end of the week, then next month, then next year, or noodles $3 extra, etc etc. If they were just straight with people instead of making it all seem like a gamble I'm positive they would sell much more then how they currently (normally) operate.

Re: Chinese SC/AM831 Group Buy Anyone know the price for one frame before shipping and everything? Curious what kind of discount all this is for?

They don't seem to be very accommodating considering one of their employees came here and suggested a group buy and prices (at least I think so but could be confusing things since it's been over a year...) But they have to understand this is a website with people all over the world and not a business or a club from one area. There have been well over 50 people interested and probably twice that or more. And now that it's here but having to pay one person that no one knows, though I'm sure you're a good trust worthy person, then pay the rest to the company down the road, it seems like a pain and there are additional steps where something could get mixed up or go wrong, and there are now 2 people so far. Thats a lot of unsold frames that people were originally very excited about because they can't offer an easier solution where everyone places their order for what they want, they get an order number, and they pay for their bike shipped to their address, and they get a discount based on how many people end up ordering.

If something was wrong with a bike who is responsible? Is Miracle not going to handle the issue for a frame they built and shipped?

These companies could sell a lot more but have some basic things they need to understand and learn first. Transparency and uniform pricing and ordering are some big ones. A website with basic pictures and having to email to get *the price* and to place order doesn't help. I'm rambling but it just seems strange to me that a business that's trying to make money but makes the process difficult and with minimal info and just seems like doing things to *not* sell stuff.

I'll still buy one if anything ever happens. Or I'll wait until other frames come along that I like if it doesn't happen...

Re: Heavy Hitter Division (XL Frame, Riding style untamed) You might break anything with enough time? Hard to answer. But some of these companies might add an extra layer of cloth if you explain your situation and let them know strength is a priority over weight. Though this is a guess, many are willing to make changes if you ask and pay a little more....

Re: Juin Tech GT-F brake calipers (dual piston) I wasn't thinking about road bikes. Disc brakes on road bikes were just starting to gain traction when I last had one so I won't ponder things I'm not familiar with. But I assume they have come quite a ways since my set of (mtb) cable pull calipers.

Thanks for clarifying your use and why you opted for them.

Re: The Shiny New AM831 Group Buy (A) Thread! This frame is modeled after the hightower but it's not an exact copy so it's close but not exactly the same. It also doesn't have the flip chips and the cascade link changes kinematics and I think I remember is 10mm longer in at least 1 dimension so I'm sure it does change things from how the original behaves. While it's possible the seat could buzz the tire, I'm betting the specified 210x55 will work just fine.

I have most parts except for a few still trickling in and was told about a week ago it was heading to paint so hopefully will ship soon. I can try to document the build with pictures if anyone is interested? We are the first ones building it up and can hopefully help each other out if anyone has problems.

Re: The Shiny New AM831 Group Buy (A) Thread! The frame is a close approximation of the original with the same dimensions, but isn't an exact copy. I don't think I would expect anything off the original to bolt right on to this one. It might fit, or fit with some modifications but it would be a complete gamble and might not even be close, IMO.

I would like to disagree. When i changed my ican p9 top bushing to a roller bearing the suspension was so much more active. The force needed to start compression was significantly less. In the end it all depends on the suspension platform and how much rotation does the bushing experience

I agree. Hard to tell how much difference it makes in the middle and end of the travel and is probably the equivalent of a little less dampening, but for the small stuff it makes the shock much more active. On the last bike I installed it on I had to increase the shock pressure because it also allowed more sag.

For this frame it's the 22 mm mount that benefits from bearings. I already have the RWC 22.2 mm as well as the 0.5 mm washers ready to put in the shock. Just waiting for the frame to double check the width.

The last time I installed the RWC bearings they were still running smooth after 4 years. There was a small clunk if I lifted the rear end and took weight off the shock but it was never felt while riding. It wasn't in the bearings and according to RWC it was normal in some applications so I stopped worrying and trying to troubleshoot it. The only thing I could figure was that the mounting bolt was slightly smaller than the hole in the 'axle' that ran thru the needle bearings and it never seemed to have a negative effect other than feeling a slight clunk when lifting the bike.

Frame flex shouldn't matter. The 22.2mm is the lower  eyelet that connects to the metal linkage. That thing feels solid. I don't think its going to flex. The .5mm bushings you sent in the link look good, but I think they may be too big. People have said 22.86 works, so 22.2 plus another two .5mm shims give a us 23.2mm. I'm thinking that might be too thick. The shims ar only two bucks so I may order some to try. Your soda can idea is interesting.

Yeah, without the frame in hand (supposed to be monday) I was picturing the front mount even though I know that's 30mm. My mistake. I have those shims in hand as I was making an order anyways and I will post how a 22.2 spacer and one fits as soon as I get the frame if anyone is interested. I would imagine different thicknesses are available on eBay or McMaster and similar if someone rather buy them.

With those shims you can use just one, bringing it to 22.7. So that's 0.16mm which can't be much more than a sheet of paper if that. At some point it will have to be considered close enough or figure out some custom thickness shims whether made or bought.

I've made many shims over the years from soda or beer cans and they work well. Sometimes a plastic bottle works too, and come in a wider range of thicknesses.
