Hi, I'd like to share my experience with buying a wheelset from ZEN. I'm very happy with the purchase so far. Zara was amazing to communicate with and helped me build out the specs I was looking for. Amazing customer experience, I must say.

I ordered everything over WhatsApp, and from the time of payment (PayPal) to when I received the wheels in the Czech Republic, it took about 6 weeks.

Specs I went for:

(The specs are inspired by the No.6 52/58 wheelset.)

• Front: 50mm depth, 25mm inner, 32mm external, 350g
• Rear: 55mm depth, 24mm inner, 31mm external, 450g
• Both hooked, tubeless-ready, with drain holes
• UD glossy finish
• Load limitation: 120kg

Hub:

• ZC235RC
• 36T ratchet system
• Center Lock
• Ceramic bearings
• Black color
• 20/20 holes
• HG / XDR / N3W / MSR freehub

Carbon Spokes:

• Front: 3.25mm width
• Rear: 5.1mm width

Weight:

1173 +/- 30g
(Actual weight was 1201g, see photo.)

Overall, I'm very happy with the purchase. Although I've only done one ride on the wheelset so far, about 80km, it's too soon to say how well they will hold up. However, my first impressions are that the wheelset is very stiff, and it feels really cool and fast to ride out of the saddle. Based on this i'd recommend the ZEN wheels.

So I finally received the replacement frame. For context, a couple of pages back I posted about an issue where my bottom bracket thread became loose, and I was offered a replacement frame if I paid for paint and shipping.

The frame looks to be ok. I think they cheaped out on the paint job, and it is honestly quite shitty compared to the original frame I had, but it's close enough, I guess. It seems that at least they faced the brake mounts and BB. I put the bike together and rode 100km on it today already.

It felt maybe a bit stiffer than my previous frame, so they might have made some modifications since I got mine (February 2025).

Nonetheless, I will not be buying anything else from Tantan. Even though I had quite good customer support and they were always helpful with everything, I just had too many problems with it. The frame itself is really a great ride for the money — it feels good to ride, it's comfy and really fast for my recreational riding.
Wish all the rest of you guys more luck with yours down the line!

I meant that im not very optimistic about the frame now, i've had quite a few issues with it and it's just really annoying at this point.
As for the Tantan i hope they will honor the warranty in some way, they did do it with the fork last summer so lets see, i will definetely post update here once i get a response.

Ill use this thread to shoot a quick question, does anyone know which ryet saddle is the closes to the selle italia boost slr s3? Thanks

Thanks, job done for free  maybe you have a link for a front computer mount file to print in 3D? 

Np, looks good!
Unfortunately, there are no good free Garmin mount models for the roval rapide cockpit. You could try this one: https://makerworld.com/en/models/575072-garmin-mount-for-integrated-handlebar, but in my opinion, it's not the best. I just ended up getting the mount from the guys over at https://www.magcad-designs.com/. They have really nice designs, and the quality is fantastic.

What a read since my last visit! Looking forward to Patric's review. It would be interesting if he could get more background info from TanTan about this frame but i doubt they will share anything more.

Quick update from me. I replaced the fork and everything is working properly. It actually fits better than the old one, with a smaller gap between the top of the fork and bottom of the headset. Since I had to disconnect the hose anyway, I also swapped the headset spacers and top cap for original SL8 ones, which fit much better than TanTan's. See attached pictures.

quick response to the question in between that mayhem 

did you guys got the Di2 Rear derailleur ICR grommet with the frame?

Yes, it was in the packet with other accessories.

Hey all, I have some unfortunate news. After one of the last rides, the bike developed a rather audible click when pedaling out of the saddle. 

I inspected almost everything on the bike and decided to try the fork. Well... when I press on the left fork (where the brake hose is), I can hear a loudish click.
There are no visible cracks or anything, not even a scratch on it, so it must be something internal.

I decided to contact Tantan before posting about it here. They responded to me the next day. They did not ask any other questions and asked me to send the video to their email.

Video of the clicking sound when pressing on the fork: https://drive.google.com/file/d/1J765PYjNBo1g4itk9wbHsPzLy0kQR7P4/view?usp=drive_link

After one day, I got a response that they would arrange for the fork to be painted (10-15 days) and send it to me via DPD (another 10-15 days). I assume it will be free of charge, there was no mention of payment whatsoever. I also asked if the fork will be the same or stronger. I only got a one-word answer, "stronger" fwiw.

I wanted to share it here after I got a response from TanTan. Considering the way they responded, it's quite reasonable customer service in the end. I don't want to raise any alarms or anything else, just posting my experience.
 

The rear bolt is the main bolt for tightening, and I torque it to 5 Nm. The front bolt is used for adjustment because tightening the rear bolt pulls the rail down, which in turn tightens against the front bolt. Does that make sense?

It’s a bit fiddly to set up.

I grease all the bolts and apply carbon paste on the rails as well as on the front and back of the seatpost where I tighten the wedge clamp to 6.2 Nm.
some may however to this differently but thIs is the same as what i do on my SL8

I can also recommend the MagCad Design mounts. The one I posted about in the earlier post is really good. There are no wobbles. It has been rock solid on the past three rides
