For those asking about zero seatpost. Here's the measurements of the seatpost:
front view: 26mm
side view: 45.5mm

not a very common measurements as far as I know. But check out this Ali ad:
https://www.aliexpress.us/item/3256807058255216.html
look at the SP045 seatpost, at least one of the measurement matched, you need to confirm with the seller about the side measurement and whether it's zero offset (looks like it could be).

Wishing you luck finding one on Ali....

Hi

Has anyone find a zero offset seatpost to match this frame design ? Desperately looking for one as Tantan does not make it.
Thanks,

Hello Everyone

I wanted to update you on the riding experience after an intense weekend of riding

Friday : solo endurance ride 130KM - 1350mD+ - 206w average for 30km/h with the Tantan
Saturday : Group ride 100k - 1000mD+ 203w average for 31 km/h with my Canyon Aeroad CFR
Sunday : Group ride 130k - 1000mD+ 181w average for 31km/h with the Tantan

Overall the Tantan does not hold me back and i expect to get the same speed for the same power.

Handling, cornering, feeling at high speed: 5/5
Stiffness: 5/5
Comfort 3.5/5 The rear end feels stiffer than my Canyon. It does not filter as much. I would expect maybe more compliance from an all road set up. Definitely needs larger tires with less pressures to bring more comfort.

Overall pretty happy with the ride. Remember that my i make the comparison with a Canyon Aeorad CFR which is proven to be a fantastic bike. I am thinking about maybe changing the seatpost as a lot of the compliance on the canyon comes from the seat post. I also want to get rid of the offset

Hi, did you get all the small pieces needed with the frame? People buying the sister frame, longteng rd301-d, where missing the seatpost wedge and cover... They also had problems with rear thru axle play (to long axle) and unsecure latach mechanism for closing the downtube storage compartment. Was the sock for the compartment included?

Could you tell us where you bought the frame and how much was it? What is the frame's size by the way?

Thanks in advance for any info.

Hi. Here is what i paid. Everything was included and went fine except what i already mentioned with 105 di2 FD and chainring clearance.

The sock was included.

I will only be putting miles in at the end of the months. I will quickly know if i like it or not. Coming from a Canyon Aeroad CFR

Good looking bike! I like the white paint. It looks to have really massive tire clearance? Any estimate on what tire size it could go up to? It's a little funky that they call it a road frame but it does seem more gravely.

It is advertised as an all-road bike.

It either fits, or it doesnt. The chain is always far away from the area where the ring almost meets the frame. As long as this "almost" is more than zero by a sufficient margin to maybe allow for some flex and grit, then no problem. And sometimes you have to use a shim. I had the problem with a non shimano crankset on a velobuild gravel frame, i had to shim it a tiny bit. It just needs to clear the frame, you dont need ample space.

Well, i disagree. There needs to be a minimum gap, at least as wide as a chain width to cope with chain fall off, debris...

And in my case, my power meter does not fit. Hopefully it will with the gravel axle and 3mm worth of spacers.

Considering the price, I Choose Praxis T47 – I.B. SHIMANO.
Magene P505 is compatible with Shimano(24mm), so it will work in your case too.

If you have extra money, you can choose change the better bearing(like NTN or ZEN) or you can go Chrisking if you are rich enough.

Because there are several BB brands, find the bb with those terms and choose based on your preference : T47 internal, shimano(24mm).

Thanks for your reply.

Magene website says that T47 is not compatible with their crankset. Have you actually installed one ? Do you have pictures of your build ?
thanks,

Hi everyone

What would be the difference between Tantan and longteng on this 301 execution ? This is open mold but is the carbon layup the same as well ?

Thanks,
