Looks intersting
do you have any experience with the tubolito or ride now tubes?
how do they perform against puncture?
do they hold pressure well ?
i've read mixed feedback on various forum so i havent pulled the trigger yet....

I'm running 25c tires with the RideNow TPU tubes and pump them up to around 90-100 psi. They hold air far better than latex tubes, though I still pump them before every ride just to have optimal pressure. Puncture resistance has been quite good so far. I even had a sidewall tire cut and you could see the tube inside the tire, but no puncture. I don't have any experience with Tubolitos.

Honestly I was planning to go all tubeless since I'm already tubeless on my gravel bike, but these RideNow TPU tubes have a significant weight advantage with lightweight clincher tires. I also feel the ride quality is quite decent.

I just found these on Ali:

Updated the link with better pricing:

The claimed weight is 38g, which is a tad more than RideNow TPU tubes. From the looks of it, the Cyclami TPU tubes utilize what appears to be a threaded alloy valve stem which should be more durable. RideNow TPU tubes utilize plastic valve stems and I've had issues with air leakage (I received a replacement). Anyways good to see more options coming out of AliExpress.

If they perform as well as the RideNow tubes, these should be quite good. Sometimes I feel more cutting edge than my cycling buddies who have no clue there's a whole other world of cycling options available!

I found this on AliEx. I'm curious if anyone has tried it? Is it similar to Jagwire wireless compressionless brake cable housing? I've used Risk standard cable shift/brake cable kits and find their products close to Jagwire quality for a much lower price. I'm definitely curious to try more of their stuff.


Thanks for any feedback!

So yesterday the BR-05 brakes arrived and they look like indeed a step up from the old ones. The "lever" is longer, so i guess there is more force on the cilinder. Another great thing is the construction and setup is different which make for a better fitting of the calliper in my small size 52 rear triangle. I was fearing the slightly bigger new calliper would not fit, since the ZTTo once only barely fit, but the lever of the new calliper falls on the inside of the frame so the small angle of the rear triangle is no longer a problem.

I only tried the brakes on my driveway and the front one already seems a lot better than the ZTTO one...

I managed to f*ck up the rear brake by contaminating it with oil so I can't comment on that one. I was trying to get some (...a lot) of oil in the cable housing of the rear brake because the movement between cable and housing seemed rough and I guess it must have gotten on the calliper and pads... Turns out my rear brake cable was also worn where it enters the frame in the front, so I immediately ordered a compression-less Jagwire brake-cable set (the old was not compression-less) I am going to install in the next days. I will keep you updated...

Would you say these new Z-Race brakes to be a viable option versus the Juin Tech calipers? I also have another question, is a hex wrench required to adjust pad spacing? The one thing I like about the Juin Tech calipers is they utilize a screw knob to adjust the pads. It's really handy to adjust Juin Tech brakes while on the road to fix any minor rotor rub.

My Velobuild 177 is sitting at 7.6 ish kg with everything on it. Running SRAM Red, thick 25mm ID Superteam wheels, 29mm Enve tires. I have some Farsports Kaze wheels and The One Pro handlebar on the way, so I may be able to drop a couple grams soon 

My Poseidon X gravel bike was never weighed, but she's a heavy one. A ton of mods on this one (fork, wheels, group, cockpit, etc), but it never felt any lighter.  This one is getting pieced out and sold, so the world may never know.

Are you getting a carbon gravel frameset? I also have a built up Poseidon X which comes in around 9.4kg, but that's with a hefty 2x GRX crankset and hydraulic calipers/shift levers. GRX hydraulic mechanical shifters are heavy coming in at about 600g.

I didn't build my Chinese carbon frames/bikes with particularly lightweight components, but I think they turned out pretty light in comparison to my other road bikes.

Nice collection! Building the bikes out are quite a bit of fun. Also I know weight isn't everything, but it's nice to get a baseline idea on weight since I don't really follow the road cycling scene all that much and I'm mostly a solo rider. I notice you have the same brand wheelset on all your bikes I'm presuming, just curious which brand you're using?

I'm curious what kind of final build weights people are averaging on their Chinese frames? I understand there are a number of factors such as rim brakes vs disc brakes, mechanical vs electronic, aero vs climbing frames, etc. Also I know you can throw more money at making a lightweight bike, but I do find lightweight bikes built within a reasonable budget to be more satisfying. I doubt many of us would be on here if we could all buy an Aethos S-Works with Di2!

I've gotten my latest build down to 16.22lbs. (7.35kg) with 105 mechanical drivetrain +  disc brakes and I'm pretty satisfied with that weight as my general purpose road bike (flats, climbing, group rides). My alloy gravel bike with 2x GRX + hydraulic brakes is about 21lbs. (9.5kg), but I don't have a problem riding that bike even if weighs more.

Anyways, I'm interested to hear how light or heavy your bike build is!

It looks like the same Onirii frame that's being sold for $1K+ USD, but much cheaper. For sub-$500 USD I'd totally be interested in trying this frame out, though I could imagine it's probably not all that rigid. Also looks to be the same frame from this thread: http://chinertown.com/index.php/topic,3832.msg38867.html.

For some reason I'm a sucker for these cheap frames!
