Hi there,
After i built a GR029 with my boyfriend a couple of years ago, I am looking at Road Bike Frames this time.
I am wondering if any of you has experiences to share about the TT-X34, FM639 or FM619.
What is important to me?
Disc Brake
Thru Axle
Clearance for decent size of tyres (minimum 28 mm / ideally 32 mm).
Officially the TT-X34 has 30mm, maybe a 32 fits? What I don't like too much is the fully integrated Handlebar (means that you can play only with the spacers) and the specific seatpost.
From a frame design point while I like both, I have a preference for the FM639/FM619 (same geometry only a bit different weight so I don't know what is the difference...). Anyone has one of these frames?

No experiences from members with these frames yet?
The TT-X34 looks quite good to me with at least 30mm tire clearance. I personally would like to go 32mm though....

FM639 looks elegant but only 28mm tire clearance.

currently I have the x34, I will measure tomorrow. I also plan on posting a review after I put some miles on it.

Looking forward to that review Nick!
The X34 is currently on my shortlist. The geometry suits me in a 52cm. Also like the look of some of the Velobuild options so will be interesting to compare your experience with others who have built the VB frames.
Kind Regards,
Mikey.

Looking forward to hear your opinion on maximum tire width. A full build and ride experience post would be great!

That would be great! Thanks!

Nick 2000 just posted his experiences of the TT-X34 here:

OK finally a decision was made to order a TanTan FM639 frame with handlebar.
Custom paint for 1 color is now around 100 US$ 2 colors 115 US$ and 3 colors 130 US$.
Are there any FM639 users in the forum that can share their experience?
The frame will be built up with Shimano 105 Di2 and Elitewheels.

for what is worth, I have a fm009 from TanTan and the building experience has been quite bad. It had a flaw on the rear derailleur hanger bolt, I had to fix it by myself while TanTan ghosted me instead of providing me a warranty service.
-
Sorry to hear you had a problem. This is my second TanTan bike (Gr029) and I am very happy with the first one. The FM639 has thru axles so I don’t think we would have a problem. In any case we have tools to align the hanger, derailleur ….
Will let you know how it goes

I've got an FM629, the rim brake version of the FM639.
The headset included was terrible, and the frame uses a non standard bearing depth for the top bearing, so you have to custom make a suitable spacer. Apart from that, the frame is great. However, it has a very slack seatpost (73 degrees) - be aware of that when considering the reach figures in the geometry chart. You might need to push your saddle fully forward to get it into the right spot if you don't normally run an offset seatpost (even though this is a straight seat post).
In terms of bike feel, the bike climbs beautifully. The steering is not very twitchy so it feels solid and tracks well even on the biggest out of the saddle efforts. But the flip side of this is that it isn't as sharp and precise on the descents, I've found it tends up understeering unless you force it into corners.
-
Thanks a lot for the detailed feedback and the heads up with the headset. Yes I realised the Seat Tube angle is at 73, considered it on Geometry Geeks analysis. As I have long legs I wnt with a slightly bigger frame so the saddle is not out that much. Having a higher stack should add on the more relaxed position. Happy the bike is not too nervous, while I love climbing, I am not the lightest so stability in descent is appreciated.

Hey man. With my experience i think you should go with Winow FM166, which is better than TanTan. They also have FM237 for aero and FM238 look very similar with Elves Falath Pro (im check at their website and every number are the same, so magic. Maybe they OEM for elves).
-
SamSida the bike is for me, ChrisB is helping me building it. I have long legs and a shorter torso. My mobility is not extremely good neither. On top I like more classic style frames, only few aero frames are beautiful in my opinion.
Hence I have checked around and the frame that I liked the most, had decent tyre clearance and did not have a dropped seatstay was the FM639. Another point for Tantan was that they sell on Aliexpress, which was very useful a couple of times were the seller did not comply (on top of being happy with my first one the GR029).
I realised now that the same frame is available with Winow under FM219 but with Toray 800 instead of 1000.
At the end there is a limited amount of open mould and the same are probably used by many producers, this is the reason why you see a similar frame offered by different brands. But thanks a lot for your suggestions, I think it is very useful to have an idea of what kind of producers and frames are around!

Just bought the tt-x34 from OG Evkin without handlebar. The price was 447 euro including shipping, so can't really do better than that. Other forum users have reported good build quality from this brand. We'll see what happens when it hits customs in mid-May.

It took a while but here we are...
The completed bike with FM639 frame from TanTan / Seraph:
- Custom metallic colour, looks better in real life
- Shimano 105 / Di2 with 50/34 - 10-34 2x12 speed drivetrain
- Elite SLT Disc wheels 40mm deep and 29mm wide
- Schwalbe One tubeless tires 30mm wide
- Mixed 6D saddle (might be changed...)
- SPD mountain bike double sided pedals
- Weight including garmin mount, pedals and bottle cages: 8.3kg
Built up by the new owner with a little help and tips from my side.
She is very happy with how the bike rides after the first short round.

looks great, you think a Deda DCR stem would work with the frame?

Also looking for the TT-x34. 447 Euro including shipping seems like a heck of a deal. Where did you buy it? Did you recieve it yet?

I think it should work. I see that the cables need to go out on the front side, which they do and your stem has an adapter for 1 1/8 (stem is 1 1/8 - 1 1/2). The spacer look very similar as well...
If you want to order without the handlebar it will be FM619.

Updating an outdated thread. Oh well.
I just received my TanTan x34 frameset. Gloss black finish with the faint visuals of raw carbon underneath. Pics coming soon...
