Re: Carbonda fm936 Thoughts Hello, I've been following along on this forum for quite a while to pick up all kinds of tips and experiences (thanks to all of you)... then decided to make my first bike build ever.
After a long time of collecting parts, I finished my build last week and in the meantime made a first ride (in the flatlands of flanders  :D )...
It's no comparison to my 11 year old 26" Rockrider hardtail  ;D

It is a size M frame (N not SL), Elite wheels, Sram GX groupset and Marzocchi fork (was the only fork available and within my budget).
Maybe not easy to see in the picture but the colors are candy red and silver metallic.

Re: FM1001 / FM1156 - 135mm frame
Love the color! I got my frame yesterday. Really happy with the frame and I agree that it does look pretty sick. So far I only have a rear shock and the fork will be here today.

Yes, please post a build list. One thing I'm curious about is what shock mounting hardware you went with? I measured my frame at 29.5mm x8mm. I read a few pages it should use a 30mmx8mm

Mounting hardware was 30mm x 8mm, purchased from bouncecycles on eBay (located in UK).  I also bought the DU Bush Tool (LBS said that tool was necessary to install).

Build lists:

Size L (teal) - rider 6'0"
Shimano SLX 10-51 cassette
Shimano XTR chain
Shimano SLX 32T chainring

I got the chainstay protector from Santa Cruz ($10 + shipping) and had it cut to fit the chainstay.

Did a few miles this evening, bike feels great.

Re: FM1001 / FM1156 - 135mm frame
looks nice! what weight?

L is 30.0 lbs (carbon handlebar, lighter spokes)
M is 30.8 lbs (alloy handlebar; heavier spokes, heavier pedals)

Bought the Dengfu M08 complete bike - I was in for a surprise. Rewind to early this year. After being completely fed up with the piece of crap that is my first bike ever - a USD$150 26" Walmart bike, I decided to get something a little bit more pro. I had a mindful budget and headed over to the cycle shop. Well, they politely informed me that there was no chance I was going to get a bike from them until about winter - something about a bike shortage in the US? Hmm, ok... let me find another option.

That's when I was introduced to the world of Chinese carbon frames and bikes. Lots of reading and research led me to believe this was probably my best chance of getting a bike this year. I contemplating assembling my own, but figured that would require tools and skills I don't possess, so I opted for a pre assembled route.

Again, more research and reading led me to the decision to pick up the Dengfu M08 assembled bike (29er "Standard" level), as shown here: https://www.dengfubike.com/collections/carbon-mountain-bikes/products/m08

I direct your attention to the part that reads

The bike is pre-assembled but wheels will be discharged in another carton, totally 2 cartons.

Cool, that's fine. First box arrives, the wheels, exciting. I open the box to ensure there is no damage, looks good. Except, wait... there is no brakes, no cassette installed. The hubs are there, and the tires mounted, and I believe tubes inside even, but that's it.

Arrive the 2nd box. Again, no damage, but...



Well crap. I expected pre-assembled to mean something else. I suppose the frame is pre-assembled, yeah? Having no idea where to go from here, I start watching youtube videos. SRAM has quite the youtube selection, which is good considering most of the equipment here is SRAM stuff. Basically I binged bike assembly videos for the rest of the night.

Confident in my skills, I went about assembling this thing. I got good use out of my torque wrenches and torx and hex sockets. I enjoyed making a tool to press in the SRAM DUB bb, as well as a clever way to press in the tapered headstock. I trimmed my fork with a pipe cutting tool, that worked well. The headstock had a split ring for the tapered fork, and it used an expanding nut for the fork cap instead of a start nut, so no special tools needed for those items.

I only had to make one trip to the bike shop - pick up a SRAM front caliper spacer for 180mm rotors - something Dengfu did not include. I also grabbed a cassette wrench adapter, chain breaker, a bike stand, shock pump, tire pump, grease and carbon gripper, and a SRAM brake bleed kit - something that my research told me I'd need if I was shortening my brake cable. I also picked up a new dropper post lever, the one that came with the Zoom dropper seat was of really poor quality.

A couple of issues I ran into: I needed to break out the Dremel and grind down the screws that held in the internal cable routing guides - they were too long and rubbed against the fork when it was fully installed. Also, I needed to drill out one of the guides to accept the dropper post cable, the hole was a bit too small.

But, never even having worked on a bike before, I managed to fully assemble this selection of parts:



Now, I have to figure out how to tune it, and then see if it falls apart on the first trail I ride.

Re: FM1001 / FM1156 - 135mm frame The material is 3M Clear Paint Surface Protection Vinyl Film (6 Inch x 60 Inch) on Amazon:

https://www.amazon.com/gp/product/B004VG8DS0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Also, the black bottom bracket shell protector is by Salsa (but I don't remember which frame). It seems okay, not hardened plastic.

Re: FM1001 / FM1156 - 135mm frame Here is my bike-build. Made my own logo and painted myself.  :D
Running NX drivetrain, Fox 34, Fox DPX2 and SLX brakes. Very happy with the bike so far.

Re: FM1002 / FM1166 - 150mm frame
That should even work with a OneUp V2 210mm.

If my diagram is correct, you'll have about 330mm of space between saddle clamp and seat clamp. The 210mm OneUp V2 will stick out about 60mm and has a stack height of 33mm, so 320 - 60 - 33 = 227mm possible dropper travel. The OneUp is pretty compact though, so a different brand might give you a lot less.

Thanks for the help! I am looking at the PMW loam dropper that has a full insertion length of 290mm and 200mm of drop and I'm pretty sure it would just about be the right. I did the dropper size calculator on there website and it says 200mm drop will work but will hold out till I have the frame just to double check, the weather is Scotland is pretty bad for a few more months so in no rush to build up the frame and want everything to be spot on! Will be ordering the frame on Monday and very excited to get it.

Will keep everyone on here updated on the build  :)
