TFSA has been rather quiet, but I just noticed they've released some new frames. I bought their older JH-06 disc frame (an SL6 clone) awhile back and had an overall good experience buying from them with solid communication, ample photos before shipping and secure packaging upon arrival. Only downsize is their shipping method is a bit slow (took over month to deliver). Also it appears they've raised prices as well.

The JH-15 is really nice, except for that super low stack: 540 in size 54. That is just too damn aggressive for the average Fred (i.e. Me). My custom titanium has 60 mm taller stack than that

I do a lot stretching and strength training (deadlifts, pull-ups, back rows) just to maintain a low riding posture. Also a back roller and massage gun help! ;D

It's pretty normal for a race frame - I wouldn't call it super low. For example, a Specialized Tarmac is only 4mm higher for the same size, and a Canyon Ultimate is 1mm lower. A 600mm stack for a size 54 would be very tall, that's 25mm higher than a Trek Domane, which is one of the tallest endurance bikes.

JH-10 looks aerodynamically sound, though probably as comfortable as a brick. The way they use the seat angle to increase the size is very weird though

Don't listen to me, I am a weirdo. But will have, finally, no spacers in my next bike ;D .
Actually it is just 1cm taller than the Canyon endurance CF7 in size M, for a similar (4mm longer) reach and similar top tube (2mm shorter). So not that crazy tall.

I actually like how the JH-10 looks for an aero frame. Also that bottom bracket area looks fat, I bet you can really put down the power. Though I think I could see my self riding the JH-15. I like the high seat stays on that frame and the weight seems decent.
-
Frame reach of 390mm with a stack height of 582mm for a size 56 JH-10 is considerably upright for being advertised as an aero frame.

Don't look only at the reach. The top tube is really long because the seat tube angle is quite slack. Actually the geometry in that bike does not make much sense. I would have expected a much more vertical seat tube to move all the weight to the front and get a much more aero position and more efficient pedaling.
-
Stem length for their cockpit maxes out at 110mm.
It’s another one of these framesets that won’t work for people taller than the average bloke. I’m 190cm with long arms. I could maybe make a size 56 work. But I’d probably have to get a 130mm stem. That’s almost impossible to get as an integrated cockpit. Cool frames, though.
-
Seller shipping method is Free, so if that is correct this could be a very cheap frame for EU. A little over 500usd.
But I highly doubt that is correct.
-
There seem to be some more new frames from TFSA. I really like the looks of this one: https://www.aliexpress.com/item/1005006306017776.html
Edit: never mind, this seems to be the SL7 inspired frame that they already had for a long time. It looks like they did change the paint/logo's
-
JH 15: The shape of the front of the headtube looks completly round in the render images. The other shapes of the down and seat tubes dont look very aero to me eiter. I doubt they ever but this frame in an wind tunnel. What do you guys think?

I think that frame takes quite a bit of "inspiration" from the Cervelo R5. If anything, Cervelo did the wind tunnel test for TFSA! ;D
My first carbon frame was from TFSA and I'm still riding that bike two years later with thousands of miles on the frame. Part of the reason I bought from them was due to excellent communication from purchase-to-shipping. I'd definitely consider buying another frame from them again. I'm actually surprised they're not as popular on this forum.
-
I wish the light frame had a round seat post. Tired of proprietary seat posts
-
Anybody have experience with the JH-10 aero frame? Thinking about building up a stiff aero bike for crits.
-
Man, TFSA always has unique colors. Their old frames also had great colorways.

The JH-10 looks absolutely sick, and advertised 950g is incredibly light for a frameset, and like others have said, it looks fast in all the right places--deep tubes, fairly narrow headset clean lines, shields the water bottles.
BUT as Patty and others have pointed out, the geometry is not great. 72.3 degree seat tube but no zero-setback option for the seat post? Not great. Narrowest bar is 380mm with a max stem length of 90mm? Not great. The 582mm stack for a 56 is wild to me--my Seka which is supposedly "endurance" geometry has a 571mm stack. I support it--it supports very new school "tall and long" bike fits that I like. But damn it's tall bike.

Yea I think the sizing is like one size off. Their 56 is almost a 58 from other places. Look at the top tube length, 575. That’s almost the same as my 58 Tarmac SL7 at 577. If you go one size down than normal, it’s not too bad, albeit short reach. I’m normally a 58 but would definitely do a 56 here.
The other frame I was looking at is the BXT aero frame, the one that looks like the previous model Madone.

Yeah I just cross referenced their geometry chart with my current aero'ish frame and it would put me on their 47cm frame. I'm not that tall, but I didn't consider myself that short either!
-
They had the perfect opportunity of labeling their sizes as per the ETT length but they didn't. Like All-City where they label their frame as size 52 and then put a sticker on top tube "length 540mm".

Seka Exceed isn't endurance geometry, it's just not a stupid long and low geometry, which suits only a small minority of riders. Also, sizes have always been inconsistent across different brands, there's no universal size M or size 54, that's why you should always go by geometry chart rather than listed frame size.
Size 52 JH-10 has 540mm stack, 385mm reach and 550mm top tube, which is quite in line with other aero bikes in most common size (M/54).
I.e. size M 2023 Giant Propel - 388mm reach, 545mm stack, 550mm effective top tube, 73° seat angle
Size 54 Trek Madone gen 7 - 386mm reach, 541mm stack, 543mm effective top tube, 73.7° seat angle.
Size 54 Teammachine R - 387mm reach, 548mm stack, 552mm effective top tube, 73.5° seat angle.
Size 54 Scott Foil RC - 389mm reach, 548mm stack, 550mm effevtive top tube, 73.6° seat angle.

Just out of curiosity: From which frame is the TFSA JH-10 a nock-off?
I saw that BXT has the same frame under code ROAD-075 only it's made with T1000 and TFSA uses T800-35T.

The BXT-075 is not the same frame, the 075 is an older design that doesn't have full internal cable routing, if you pay attention to the details of the design you'll see many differences.
The JH-10 isn't knocking-off any specific frame in particular. I guess the fork/headtube area bears some resemblance to the Scott Foil but it really seems to be an original design
-
What is 35T ?
-
I know this is an older topic. But I have a question. Does anyone happen to know how or if it is possible to order tfsa frames to Germany? The AliX store states that it is not possible to deliver to my address. Has anyone from Germany ever ordered from tfsa?

From which store do you try to order ?

I only found this one: Huzhyi-TFSA Store (https://a.aliexpress.com/_EQ75lMC)

This is weird because It can be shipped to France.

BE also no problem.

Yes, it is a problem with Germany. If I change the shipping country to Austria in the app, I get a shipping method and a price displayed. I don't understand it, too bad they don’t ship to Germany
Edit: I wrote them on AliX. They don’t accept orders from Germany:

Did they explain why ?
-
Nope, this was their answer. I didn’t ask for an explanation.
-
It's possible TFSA is an OEM for a German bike brand. That brand might have regional exclusive rights, hence TFSA doesn't ship there.
-
Wow that JH-10 looks strikingly similar to the new Winspace c5 Aero
-
TFSA seems quite popular in China. If 105 is the groupset for the people, TFSA frames are the equivalent over there. On Chinese social media there seems to be a passionate following for the brand. ;)

Yep, I think so too. I don't know where all these dealers are. All the frames I like cannot be delivered to Germany. Speeder, for example, doesn't deliver to Germany either - for the same reason.
I tried my luck at adapt and asked if they might sell to the end consumer after all. Maybe I'll be lucky
