I think they actually have BSAP stamped on them, my eyes aren't great. On my other wheels(Winspace) the spokes say SAPIM.

I read that they r real now. I also measured it all, looks good. my bad

Garbage.  Do not buy.  They look cool and are light.  Set up is finicky and braking power is reduced, too much flex. Waste of money.  A good set of Ultegra R8000 calipers are all you need for rim brake. 

Check our the reviews of the actual G4s on weightweenies.

I think anyone saying G4 have less stopping power have their brakes setup improperly or they have counterfeit bushings. I have textured braking surface as well but when I have the EE G4 setup correctly, they are the most powerful rim brake I've used, more powerful than my dura ace.

You have to replace the counterfeit bushings with authentic ones. I did that and got like 50% more performance lol these are powerful man, they're like disc brakes. I have to really be careful. Could easily go over the bars doing higher speeds.

What kind of affordable options do we have currently for a nice light rim brake frame with 27.2 seat post with the clamp? I have a winspace slc 2.0 RIM and like it allot.. speeder had something similar but they wouldn't sell me less than 10 and it make me want to cry.  I can pitch for 2-3 frames if anyone wants to do a group buy.

What options do we got in Chinese carbon world

Dear Enthusiasts,

I hope this message finds you well. I am coordinating a group purchase from Speeder and would like to extend an invitation for you to join us. To meet the minimum order quantity of 10 frames, we currently have six committed participants, all opting for the SC4R8V model. However, you are welcome to select a different frame model if preferred, as I believe flexibility is possible.

For clarity and convenience, I will solely facilitate the organization of this group buy. All payment, shipping, and personal details will be handled directly between you and Speeder, ensuring a seamless and secure process.

If you’re interested or have any questions, please feel free to reach out. I’m happy to assist in making this a smooth and collaborative experience.

Warm regards,
