Hongfu FM358 build
« on: July 11, 2025, 03:31:08 PM »
Well it’s a go, the frame is paid, just have to wait for a couple of months now.
I will be transferring most of everything from my hardtail onto this frame. Just ordered a rockshox SIDLuxe ultimate 3P in 210x50 for it and also looking for the matching SID SL 3P fork to match but I am ok to start with the SID SL I have now to start with.
The big unknown right now is the headset, need to research some more the options

Paint scheme as below, somewhat racing inspired (lotus, caterham…)

I guess its the same setup as the lastest version of the Scott Spark?

This might work:https://www.tradeinn.com/bikeinn/sv/syncros-zs56-28.6-zs56-40-mtb-styrlager/141631705/p?utm_source=google_products&utm_medium=merchant&id_producte=146073131&country=se&gad_source=1&gad_campaignid=19971358487&gbraid=0AAAAADvzHL_DZTbdKk0K5slyps_O9zgkz&gclid=Cj0KCQjwj8jDBhD1ARIsACRV2TuC0RXMzc5Qf1FFXye6feZEUoAHhtSCNACHHQe4wSwrLCBCYYiCPC0aApWmEALw_wcB&gclsrc=aw.ds

Or any brand fit to match the Scott Spark

But the headset must come with the frame.

The quote they sent me included it for $15, as did the rear axle, also for $15.

I'm looking forward to it arriving so we can see it.

No Helen messaged me, they don’t have a headset solution for it yet. Accros has one but it’s $130 so I would love to find something more cost effective. I think I found a ztto one, the question will
Be the integration with my syncros bar…

I also need to find a dropper post, light and cheap-ish

The oneup v3 dropper might fit your needs, around 540g for the 210mm version and currently about 200€ - not too bad in my opinion

Is there a big improvement over the V2? I have found the V2 at really low price on Jenson IIRC

OK for your size the raceface seams like a really good deal. You could even tune the weight by using lightweight yoke parts (mix n match from carbon seat post)

OneUp v2 is like 50g heavier thru all sizes than the v3 version btw.

Having a well-prepared frame and not having a headset designed for it doesn't give you confidence to buy.

I hope you find the headset for it, and that way you can guide other users.

The canyon it’s based on has a headset that allow for Ht angle to be adjusted, not something available yet on Chinese market but it’s on the market. I will get one of the first frame, it comes with some inconvenient, I am ok to deal with that…
They are also working on sourcing, I don’t doubt they will figure something out.

It looks like a good frame. What size did you choose?
I'm curious to see how the complete assembly turns out.

isn't headset like FSA NO. 55R as indicated in their website?
i'm also looking for this frame, but this heavily integrated cabling model is a thing that scares me a lot (carbonda fm936 happy customer here!), i'm keen to change brakes trying new ones etc etc so it's a choice i could regret, moreover i would also look for an electronic gearset to save one cable at least.
