Title: Hongfu FM358 XC 120mm frame
Post by: Ludo on June 14, 2025, 04:56:20 AM
Just saw this new frame while browsing on their website. Looks pretty good, still need to compare geometry to current XC frames to get an idea of what it could be like to ride.

I saw it last week.

I asked the seller for information.

Here's some pricing information they gave me:

FM358: $680
Headset: $15
Axle: $15

We will use WXY to ship to Spain; the shipping cost is $180/set. The price includes customs tax. You don't need to pay customs tax.

Total cost: $680 + $15 + $15 + $180 = $890 in UD matte or glossy black.

I think the brake caliper is flat-mount...

I was eager to try the frame, but I don't have that brake system. I'm a SRAM Level user.

I don't think many brands mount it like this.

Are there any flat-mount to post-mount adapters?

You can use some of the sram road calipers. Here's an official compatibility chart. https://www.sram.com/globalassets/document-hierarchy/compatibility-map/mtb-and-road-hydraulic-disc-brake-lever-and-caliper-compatibility.pdf (https://www.sram.com/globalassets/document-hierarchy/compatibility-map/mtb-and-road-hydraulic-disc-brake-lever-and-caliper-compatibility.pdf)

Yes, plenty of adapters.


Frame weight in M is 1910g, so no weightweenie hopefully sign of solid frame…
Still discussing with Helen, on the fence between that and the SPCycle M868. There is about $150 difference on favor of SPCycle but I visually prefer the Hongfu. As far as riding, both frames capabilities exceed my own…

I would like to ask you if this adapter is compatible with your frame and if the flat mount clamp would not touch the chainstays.

Post by: niklass on June 24, 2025, 01:59:09 AM
Looks really nice!

Regarding the storage, its the same solution as Orbea has i guess. I have a Occam SL with that Solution and it works perfectly fine!

why does this bike call for a 210x55 rear shock? thats 135mm of rear travel and yet its 120/100 travel?
Title: Re: Hongfu FM358 XC 120mm frame

XC frame with 210x55 rear shock
Let's check out XC rear shocks
You can only fit FOX Float SL 210x55
RockShox doesn't have a SIDLuxe model in that size. Max is 210x50
Title: Re: Hongfu FM358 XC 120mm frame

Deluxe ultimate available in that size I think
Title: Re: Hongfu FM358 XC 120mm frame
Post by: borysgo2 on June 24, 2025, 11:11:38 AM
Have also some more details about frame size.
210x5X shock is popular enough, there shouldn't be any problem to get it. The only thing is not so many of them with the remote.

Cable routing is only headset - I have asked that question already to sales team.
But I think there should not be a problem to DIY it Yourself.

I am waiting for You to buy it first   :D

I have lcfs918, but prapobly will sell it, so I was thinking about LCFS980 or FM358. Priority is that frame must have room for two water bottles.

Post by: federic000 on July 01, 2025, 04:46:41 AM
very nice indeed, i hope it weights under 2kg's though.
i see FM138 users are pretty happy with it, no broken frames or other issues isn't?
Title: Re: Hongfu FM358 XC 120mm frame
Post by: Ludo on July 01, 2025, 05:29:13 AM
1910g in M and no paint.

It’s not a light frame, but I would rather trade 200g for added reliability
Title: Re: Hongfu FM358 XC 120mm frame
Post by: impmonkey on July 01, 2025, 05:23:36 PM
On the verge of ordering this.
I have asked in email about the post mount adapter compatibility, shock mount type (standard or trunnion), rear cable routing route, etc.

I'll post if and when I get an update. They have been responding pretty regularly so that's nice.

Prices quotes:
Frame: 680
Headset: 20
Axle: 15
Single color paint job: 100
Slow shipping (tariffs included): 190

Title: Re: Hongfu FM358 XC 120mm frame
Post by: Ludo on July 01, 2025, 10:41:06 PM
Order in for me.
Title: Re: Hongfu FM358 XC 120mm frame
Post by: impmonkey on July 02, 2025, 09:58:04 AM
Some answers
The shock mount is standard not Trunnion.
I asked if the HA measurement was with a 100 or 120mm for but not sure they understood the question so I just got the usual: "The Fork travel:100/120mm"
Also got this answer from the flat to post mount adaptor question, again don't think they understood what I meant:
"It could not fit for a post mount brake, if need to change the disc brake mount, it will need to change the mold of this frameset."

I was told a month till the frames will be ready and 2-3 weeks to ship.
So would be a rather long wait.

Title: Re: Hongfu FM358 XC 120mm frame
Post by: Ludo on July 02, 2025, 10:07:13 AM
For me with a pretty specific paint job it’s 2 months lead time plus shipping.
Title: Re: Hongfu FM358 XC 120mm frame
Post by: RDY on July 02, 2025, 12:11:55 PM
Are we sure that's 210x55 and not 210x50.  Very limiting and very heavy shock options at 210x55 for an XC bike.
Title: Re: Hongfu FM358 XC 120mm frame

Little surprise, seems like they don’t have headset for this bike, it s 56mm ext ID bearings.
Title: Re: Hongfu FM358 XC 120mm frame
Post by: gas0fa on July 07, 2025, 06:44:39 AM
56mm outer bearings? Isn't that the standard 52mm?

That's a problem when it comes to finding the right routing for both the cable routing and the bearings.

A downside to buying this frame.
Title: Re: Hongfu FM358 XC 120mm frame
Post by: Ludo on July 07, 2025, 06:51:25 AM
You are correct  on 56 vs 52 standard. In the plus side that allow you to changing HT angle (accros) and presumably (I haven’t looked into it) more room for internal routing, gaining 2mm on the radius.
Title: Re: Hongfu FM358 XC 120mm frame
Post by: niklass on July 18, 2025, 09:11:15 AM
Found this one from Chinese Brand Quick Bikes. They have a good rep on road frames as far as I know, with Chinese UCI teams riding their stuff.

This looks fairly similar to the FM358, both looks and geo (slightly off, for instance 66 degree HA)

Might give a hint on how the FM358 looks built up :) I for one like it (apart from that they seem to like headset spacers a bit too much)

No, bearings are 52mm (outer ofcourse) top and bottom. I asked them and got this diagram
7mm high bearings and 45*45degrees :-)

I would like to try this frame, however, I'm really happy with my Carbonda 909 :-)
Just need something more xco oldschool(ish)

If your are think about the image of the Quick Bikes frame, i think the images shows a bike with Öhlins latest xc shock. The other images of frames on their website have regular looking shocks.

Hot tip for you is to visit your local LBS that sells Scott bikes (if there is any). I talked to the guys at my local one, and they have plenty of spare 56mm headset cups in the workshop. So potentially you just buy the cups and use the same headset setup from your old bike.

There are no difference it's a full copy see the other thread the guy had to make a custom ammo bushing because he can't find the real one, and he can't find it because it's a special bushing with a length that is made only for canyon

Hi. Has anyone tested the suspension at full travel? It looks like a design flaw. The suspension mounting parts touch each other at about 70% of the travel and become damaged. The frame suspension stops there. Im using SIDLuxe 210x50 shock.

Received the frame in February, and have done several rides in the meantime.
Frame is great, efficient and high quality, but also noticed mine is developing damages at exactly same spots at the suspension linkage hardware.
Surprised to see they just machined some material away, no finishing, paint or something.

Post by: Corneliz on May 24, 2026, 01:18:33 AM
Well spotted indeed  :)

It just fits, cable end cap is rubbing a bit against the frame, but should be good.

Ending up like this was also more coincidence than on purpose. Found a second hand Sidluxe A2 2P for only 80 euro. Since I wanted to use it with a 3P Squidlock (MP11) I had to rebuild, so ordered upgrade kit which always comes with In/Out remote cable hanger. Then during rebuilding I realised that I could combine the 3P hardware with the backside cable hanger that was already on the shock. So there we are, remote cable pulley and cable sit on top, nice and clean bike :)
I was surprised by flexibility and interchangeability of the Sidluxe A2 ‘platform’, there is many options, kits and servicing is pretty simple.

Rest of components is combination of Shimano XT and XTR (brakes, shifter, derailleur). Fork a second hand Rockshox Sid SL Ultimate 3P 110mm. Wheels are self-build with DT Swiss 240 hubs and 270gr 30mm inner width rims from Ali. Total weight of the bike will be somewhere just below 10,5kg.

Let me know if there’s other questions!

Do you think a RockShox SID flight attendant rear shock with the battery location will prohibit a water bottle from fitting on the downtube (size L)?  Looks like there is very little clearance on your current setup.
Title: Re: Hongfu FM358 XC 120mm frame
Post by: Corneliz on June 26, 2026, 02:22:45 PM
Might be a challenge indeed, although my frame is size M. With this setup I can fit a regular (650 ml) and large (950 ml, as in the photo). But it barely fits, especially the regular is quite difficult to get out, I’m thinking to get another holder so i can take it from the side.
With additional flight attended unit, don’t know if there is enough space for a large bidon.

Hi, what size is your frame? I'm curious if all sizes have this problem, because I don't see many complaints on other FM358 threads so I'm thinking that they may have only tested one size and just scaled the design for different sizes without actually testing.

Thanks!

Hi, my frame size is M (17.5)

Now I have another problem. When the rear suspension compresses, the brake rotor rubbing the pads. This also occurs when the bike leans into corners. I think it's a rear triangle stiffness issue. I contacted HongFu two months ago, and since then they've only asked for a photo of the brake mount on the frame.

In this video i push down my chest on saddle two times

Thanks! well seems like my theory was incorrect then, as others with M-sized frames have reported they do not have the problem with the linkage hardware bottoming out at 70% travel.

And yes, looking at your video, that looks like there is insufficient stiffness in the rear triangle.
