Hi , do you have any idea of rider max weight and quality of the frame. I own a Hongfu xc frame since 2020 the torpado ursus team frame . Im looking for upgrade frame high quality but must have 2 bottle mounts. I mainly do xcm races and is gets really  hot. Any info on this or another modern high quality frame. I see the ridley frame got more bottle mounts  and the head tube slightly different. Thanks for the info

Hi. So you think this is also a good buy for the price . Its $300 cheaper than the carbonda frame , but how close is the quality? My previous hongfu was very good no idea of this one

Might have to buy it to check the quality :(

but this is not a copy, but an original development used like carbonda by "brands" so indirectly there are reasons to rely on quality

Looks like a good bike, but the seat tubes are at least 20mm too long per size and many would end up running too short dropper posts IMO.

This looks interesting.  Especially as the reach on the FM909 is so ridiculously long, which doesn't really suit me.  Though as you're losing more than 2 degrees of seat angle here, the effective reach loss will be a lot less than the 40mm that the raw number suggests.

and costs less than the 909 frame. Geometry can be said to be standard for today, angles 67/76 and 470mm reach in L size

Just ordered the frame this morning. Was more straightforward than some of the other manufacturers that I've dealt with. I'll post again as soon as I receive it and give an assessment of how it compares in quality to Carbonda and LightCarbon.

i order last week this frame, my experience with HongFu are,
quality very good
service also,
delivery time very long
we will see how long this frame will take to come to Holland , the last one take 6 months, they tell me 2 weeks before finish the frame and then send to me, but last year they tell the same.
now looking for the rest of the bike,
allready order XX SL transmission group and Fox shock.

The most important and interesting question is what size bottles size into the frame?

(visually the hinge of the suspension arm protrudes forward too much, blocking the possibility of placing a large bottle)
Title: Re: HongFu FM138
Post by: danved on November 24, 2023, 01:13:19 AM
I have also just ordered a frame, with custom painting.
They told me that the paint time would be 2-3 weeks.

I have had 2 frames from HongFu before and am really happy with the quality (both road frames).
First time building a full suspension, so looking forward to it.

Post by: danved on November 24, 2023, 09:03:50 AM
It depends on the complexity of the paintjob, I just went with a single color red chameleon color (red to black) and golden logo decals (on the lower frame tube and on the upper chainstay).
Paint was $150 and decals were $75.

Yeah that's highly optimistic, and not what I was told. This seems much more realistic.

Yes,we have light weight version for FM138, and the price for frame FM138-SL is $750.
Normal version FM138,size L,weight:2080g±45g.
Light weight version FM138-SL,size L ,weight:1930±45g.
No any strength difference, if the rider weight ≤100KG is ok .


I'm in the process of ordering one, so I can report back when it arrives.

Finished my build. I am absolutely loving this machine. I'm still tweaking a bit, but still very happy. Tweaking so far includes going with a different bar, the rear sus was a little too compliant for my taste so added the larger token and I think it's good. I want to make the front a little more compliant so will see what's in there for tokens, planning to remove one. I was expecting this build to be good, but I wasn't expecting to love it so much.

Got my frame a couple of days ago. Was able to ride it a little bit, to take photos. The weather is a total mess for last week. So only asphalt ride :)

From what i found out: it has very good pedal efficiency(does not bob at all in open mode). Looks like that anti squat values are above 100% with my 32t chainring.

Everything looks to be a very good quality. Assembly was easy.

SL version UD gloss in size M is 1950g without rear hanger and axle.

Will update, when I will have more rides including offroad.

Hi everyone, I’m seriously considering of buying this frame, it’s been suggested in another topic that I opened about best 120/120 downcountry frames, but I have few questions as you had already experience with it:

1. How is your general consideration after few months of use, did you have any issues, is it still a good quality frame? Any crack or break (I mean in a normal usage, not extreme jumping or similiar)
2. Did you have any issue in the building up, with weird measures, weird pieces or other stuff?
3. Is it possible to mount a 180 mm disk brake rotor on the rear, or just a 160 mm?
4. Did you have it painted by Hongfu (how is the paint quality? 2k clearcoat or less quality)?  did you leave the black matte basic paint or did you paint it yourself?
5. Is there a big difference between the superlight frame and the normal one in terms of weight? The superlight version is still reliable or is it more fragile? Did they use different materials or less carbon?

Thanks so much in advance!! I know that are many questions, but I want to be sure to do the right thing, I know that is cheaper than an official brand frame, but it’s still a lot of money!
Title: Re: HongFu FM138
Post by: darkening on September 06, 2024, 11:23:57 AM
1. No issues at all for this summer. No creaks or sounds. Washed it many-many times. Lots of dirty races....
2. Shock remote lockout is a tricky part to setup. Links bolts are not so easy access.
3. Have no idea :)
4. Gloss black. Because it's lighter than painted :)
5. I own only SL, they say its 100gr difference. For 100$ extra, superlight version is a no brainer for me. SL version does not have additional limitations.

Thank you for the quick reply!!
You directed me towards this frame, in the other topic, right?
Just one last question, about the size of the frame: I’m 170 cm tall, and I have an internal leg length of 80 cm, what size do you suggest? S or M?
What did you choose for yourself?
Title: Re: HongFu FM138
Post by: darkening on September 06, 2024, 11:44:01 AM

Like I am. Be safe to pick size M and with 60mm stem it's absolutelly fine.

I know I said last question, but since you’re so kind  :)
What handlebar did you mount? It looks very nice.
I saw that you’re using elite wheels, are they the pro36? How are you finding them?
I was planning to buy them as well
Title: Re: HongFu FM138
Post by: darkening on September 06, 2024, 01:04:19 PM
I do use ENT Elitewheels (6pawls), 30mm internal. They are fine. I had to replace rear hub bearings after 2nd year of use and abuse. No need for truing, they are fine.

Handlebar is from aliexpress seller "Pegasus bike Accessories Store" 780x60mm.

Hello

I wouldn´t be worried. It is for water to come out of the bottom bracket. Water goes inside the frame through cable holes and the bearings don´t like it.

Good morning, I find this frame very interesting, but I can't understand the rear travel.
On the manufacturer's website it says that you can mount a 190x40 or 45 shock absorber.
How many mm of travel does it have at the wheel with the 2 types of shock absorbers? Thanks.

good morning, I contacted hongfu via whatsapp who sent me a photo of a frame in size xl, this disappointed me, because I discovered that there is an additional crosspiece in the upper part of the shock absorber.
this makes it aesthetically ugly and will surely weigh a few grams more.

I don't know, you have to ask them, by the way I discovered it by chance because I asked to see a frame with a matte UD finish and they sent me this photo, then I asked for clarification and they explained to me that the XL size has the crosspiece, if I hadn't asked about the color I wouldn't have found out about the crosspiece.

Hi. I'm reaching out to see what brakes you've installed on your FM138. I've been discussing this with Malissa from HongFu and there seems to be an ongoing issue with Shimano brake compatibility. Specifically, the M6120, M7120, and M8120 series are not recommended. Additionally, a customer reported difficulties installing a rear XT M8100 brake. Malissa suggested exploring SRAM brakes as an alternative. While this seems unusual, I won't be able to verify the compatibility issues with Shimano brakes until I receive the frame.

Hi Darkening, I’m asking you as I know we are quite the same size (170 cm), but anyone who knows of biomechanics can help me.
I’m buying some parts for the frame, and I’m not sure of some measures. What is the length of your crankset 170 or 175? And what about the handlebar? My options are 74 or 76 cm.
Let me know what you chose for your bike.
Thank you and happy new year!!!
Title: Re: HongFu FM138
Post by: thimo on December 31, 2024, 04:21:32 PM
There"s a lot of personal preference and how you use the bike involved into what is your best size. As an example, based on my experience with my Canyon Stoic in size M, I would consider this frame in size M as well and I'm 1,80. Main thinking is that I'd prefer a more nimble bike with a shorter wheelbase. If the frame is too small, you can always raise the seat post or put on a longer stem.

760mm for handlebar is a nice starting point, you can easily cut off a few cm if needed. If you're not yet used to such a wide handlebar, it may get some time getting used to.

Measurements on my own legs, both inseam and lower leg bone, indicate to 170mm crank length, but I could do with 165 as well. The 170 on my Canyon don't cause me issues. There's a trend towards shorter cranks as it increases comfort and with that power output. Your mileage may vary.

I currently use 170mm cranks, but I’d like to switch to 165mm since I prefer that length on my gravel bike. Unfortunately, I can’t find Shimano XT8100 cranks in 165mm anywhere—they’re all out of stock. I specifically need them because my power meter is designed for Shimano’s direct-mount standard.

For my handlebars, I use a 760mm-wide setup paired with a 60mm stem. The handlebars have a significant backsweep, creating a roughly 20mm gap between an imaginary line connecting the bar ends and the stem bolt.

Malissa suggested exploring SRAM brakes as an alternative. While this seems unusual, I won't be able to verify the compatibility issues with Shimano brakes until I receive the frame.

Interesting. I ran SRAM Level 4-piston on mine (size L), and ran into issues. The outside edge of the caliper contacts the frame and prevented me from the moving the brake outward enough to center the pads on the rotor. Malissa told me it was because the frame was designed for Shimano and Magura brakes only. There's just very little room for the rear brake. I didn't want to get another set of brakes so removed some material from the caliper so it wouldn't contact the frame. An annoying solution that voids the warranty on my brake for a problem that shouldn't exist.
Title: Re: HongFu FM138
Post by: Hayek on January 01, 2025, 02:24:35 PM
I meant to post this build earlier, but better late than never, and I can add a full review as well.

I ordered the FM138 in size large and had it painted in Pantone "Red Pear" gloss clearcoat. First bike I've gotten from Hongfu (I've mostly bought LightCarbon and Carbonda), so wasn't sure what kind of quality to expect but the frame quality and paint were as good as anything I've gotten from anywhere else. Everything went together easily, including the headset cable routing (I used a Deda headset) with the exception of the rear brake caliper, like I mentioned above. I did a mix of SRAM Transmission parts and LightCarbon wheels with Conti Cross King tires. I opted for 120mm front and rear with RockShox SID and SIDluxe. At 181 cm tall, I started with a 60mm stem on the size large but ended up swapping to a 70mm and prefer the feel of that more. Came out to 10.85 kg including pedals.

The Good: I've put 1500 km so far, and it's been a great bike. My last XC bike build was the FM936. This bike climbs and covers ground noticeably easier, especially in tight and techy terrain, but feels sharper on the descents, requiring a touch more finesse. In general, it feels like a sharper bike than the 936. It's every bit as capable, but takes a little bit more attention on the descents and requires less attention on the climbs, especially tech climbs. I chose not to do a remote lockout and have not regretted it. The seated climbing manners on the bike are excellent, with the anti-squat being high enough to keep the bike very stable under pedaling, and yet it has had no issue getting into its 120mm of rear travel. All told, it's a very good XC bike, and the frame details are quite good. I've enjoyed being able to carry to two full-size bottles in the frame. I used a little plastic spacer under the top bolt of the seat tube bottle cage and that small angle adjustment has kept the bottle from contacting the frame at any point. The bike is also very quiet. No creaking as long as I keep everything clean.

The Bad: I had ordered SRAM Level 4-piston and the frame didn't leave enough room for the caliper to center on the rotor. I tried 160mm and 180mm rotors and I'd still get a small amount of pad contact on the rotor no matter what. Malissa said it was a SRAM problem as the frame was designed for Shimano brakes (sounds like whatever the brake you choose to run, they're going to say it was designed for something else), but I opted to remove some material from the caliper and that solved the issue. 1,500km later and it has been a non-issue. The seat tube could be shorter to allow for longer droppers, but I was able to fit a 150mm post with room to spare. And it's an XC bike after all. If you want to run 200mm on an XC bike you might be looking at the wrong bike.

The brake is the one issue I've had. I don't want to say it's a minor issue, because it can't be fixed and experimenting with brake calipers is extremely expensive, and machining away material from the caliper clearly voids the warranty. I've been transparent about that with friends, but those who have spent some time on mine have decided that it's a minor enough con that certainly doesn't outweigh all the pros. I've had several friends order the same frame, and even have another one on order at the moment that I'm building up for another friend. Malissa was actually very good to work with and I have no complaints outside of the brake mount.

Post by: Figo on January 02, 2025, 04:52:13 AM
Hi there. Thank you for the excellent review. You've captured the brake situation perfectly. I had the same feeling that no matter which one I chose, it wouldn't be quite right. The upside is that Malissa asked me to hold off on purchasing brakes until I received the frame. Could you also share which handlebar you chose for your bike?

Thank you for the info regarding the bio-mechanics!

I have another question: I’m using the headset provided by Hongfu, it looks good quality material, but I saw that it doesn’t have any rubber sealing caps for the cover holes, where the cables come out, so when you wash the bike there’s a chance that water can go inside the down tube towards the bottom bracket, could be that an issue? How did you manage this?
I don’t know if I made myself clear  ::)

And Darkening, what power meter do you use? Is it mounted directly on the crown?
Thank you as always!!

I had LightCarbon build the "MC932GP-XC" rims with DT hubs. Those are 27mm ID, which is in line with what I like for an XC bike, but I was also aiming for a sub-1200 gram wheelset and that was the way to get there. They're absolutely awesome wheels.

But yes, if you want wider ID, maybe check out Elite. I have two of their wheelsets (Pro33 XC and gravel) and the build quality is really impressive. Their Pro36 wheelset has a 30mm ID, and aren't overly heavy.

I'm trying to find what offset the frame geometry is designed around. I have frames that were designed for a 51 that I've put 44 forks on and it definitely changed handling characteristics for the better, but I've experienced the opposite effect putting a 51 fork on a 44 frame.

Hi All ;)
I am considering this frame but have a couple of questions.
Does the rear triangle move free without tension if the rear suspension is not installed.
I was also thinking about the TanTan Fm121 but some of the customers claim that there is too much tension on the seat stay as there is such a difference in radius of the seat stay vs the swing arm (see in the picture).
Is this the same with this frame or would anyone of you be so helpful and send me a picture like this to show if the rear triangle connects to the swingarm without tension.
Picture is taken out of the fm 121 thread.
Thanks in advance

chain stays: a thin layer of white material (the frame is wrapped with when it comes) on top of chain stay and black electrician tape (not the prittiest but it works)

I have 30mm Race Face cranks so I can´t say about Shimano width. If you have or can buy thin 24mm spacers for Shimano axle, it is easier to adjust the chainline and width when the spacers are outside of the bottom bracket cups though.
