Where do you buy this?

Hi everyone, I installed some Hudud carbon crankarms with an Xcadey power meter and 40-55 chainrings. I'm having issues because the chainrings wobble laterally, and when I apply a lot of force, the chain drops off the outside of the ring. I've tried swapping the power meter and adding washers in various places, but nothing has fixed it. I'm thinking about replacing the crankarms and have been looking at the Leese Max ones; I was wondering if anyone has experienced similar problems with them.

I'm thinking about buying a new crankset to fix the wobble issue I have with my chainrings. I think a smaller chainring wouldn't make the wobble as noticeable, but since I'm running a 55-tooth ring, the oscillation at the edge is huge; the chain slips off the teeth when I put down a lot of power, so I'm worried about having an accident. I've been looking at other chainrings—Elilee and Cybrei are the easy choices, but they're a bit out of my budget. The other two options are Rpantahi and—the one that appeals to me most, even if it weighs a little more—Leese cranks. I'm not sure if anyone has experience with any other carbon cranksets they could recommend; I'm looking to spend around 200 euros.

Hi there. I've had issues with lateral wobble in the chainring whenever I install the crankset; I'm not sure if anyone else has experienced this. I've tried everything—placing spacers here and there, using a different power meter, swapping chainrings—but nothing works. The problem goes away when I install Dura-Ace cranks, so I gather the issue lies in the alignment of the crank arm with the spindle, though I'm not certain—which is why I'm asking if anyone else has run into this. I'm thinking about buying a different crankset and reusing my current chainrings and power meter. The options are: Budget: Rpantahy High-end: Cybrei or Elilee

That store is closed. Does somebody have a link to the Taiwan eisen AliExpress store?

PM

Hi, I want to add a derailleur hanger with ceramic rollers. I've seen that they have an official one from the brand that costs around 100 euros, but I want to know if there's another one that's also reliable and a bit cheaper.

Hi everyone, there might be a thread for this, but I can't find it. I need help with a 12-speed road bike chain. I've installed a Goldix 11-34 steel cassette and 55-40 Stone chainrings. The groupset is Wheeltop EDS EX 6800. According to artificial intelligence, the smartest option is a KMC X12, but I've read that they don't last very long, and I wouldn't want to break the chain and damage my teeth. Any advice or experience? I've used a KMC 11-speed without problems, but now I'm not so sure.

Li at Polar, like most sellers, claims to have the best quality frames. And they have only kits started selling that Ostro after finishing its 'development'.


A few people on the forum have bought his SL8, and the finishing looks excellent—the frame weights are also very close to the genuine version.
The frames come with a copy Darimo seatpost and bar.

I purchased the Nexum Drag copy and can say the quality is also very good. However, one issue I found was with the stem bolts: they're aluminium, and the head of one snapped during installation. Aluminium isn't great for bolts, so I swapped them for titanium. I was offered replacements but declined, and suggested they consider using steel or titanium instead.

One other point worth noting: Polar and RK Ultra—also trading under the names Mirror Carbon Fibre and First Class—are actually sourcing their frames from the same place.

So polar and RK are the same manufacturer?

Do you know if this number is still working? Seeing all your comments and being guided by BeR Sander 2177, who seem to be very knowledgeable about the subject, I've decided to buy a Polar or RK SL8. I'm waiting for both of them to reply.

Taiwan Eisen used to be considered reliable, but he was reportedly arrested last year and a lot of people were left without support after placing orders. I've been riding an X68 since last year; TanTan won't apply brand decals, but for around $795 USD it has performed well so far.

Some riders have been buying from RK and Polar. Their frames cost a bit more—around $1,000 USD—but they're offering weights comparable to high‑end models. The finishing quality is noticeably better too, and the bottom bracket and brake mounts come properly faced, much like the genuine branded frames.                         

Thank you so much, friend! This comment has been very helpful. Tantan continues to really catch my attention. If you have any links for Polar or RK, I would greatly appreciate it. I need to evaluate both, and if not, I'll join your group with Tantan x68. ❤️

The reason we're writing in this section of the forum is to share common ground, etc. It's clear that buying replicas isn't legal, but for me, paying 6k for a carbon frame isn't either. On that note, not all replica carbon frame manufacturers work with carbon fiber in the same way. I know many people who have been racing with replica frames for several years; they all get them from a guy here who has a contact with a manufacturer who's proven to be very good, but he takes a commission (as is normal). Therefore, I'd like to find a contact like that. I respect the opinion of everyone who thinks it's not legal, but I'm not asking for your opinion; I'm asking for a reliable contact. Thanks a lot, guys.

Good morning everyone. I'm interested in buying one or more SL8 replicas for myself and some friends, but I need to know of a reliable manufacturer. I contacted Tantan to see if they could make S-W handlebars and paint, but they said no. Now I have a lot of contacts on AliExpress, but I don't know which one to choose. I've also seen the Yohoo option. So I'm still undecided.
Can anyone recommend a manufacturer that does good work with carbon fiber?
Thanks a lot.

Who is the seller bro?
