Just plain bad
  • Juintech F1 brake calipers: I just could never get these to brake all that well. I tried different pads, rotors, preload adjustment, etc etc etc; ultimately I was descending a notoriously steep and winding local road and I nearly lost all braking power, even after stopping and letting the system cool down for almost 10 minutes. I ordered 105 hydraulic shifters and brakes the next day and they're infintely better. Don't bother with these or other cable/hydro solutions, just go hydro. https://www.aliexpress.us/item/2255799928780428.html

I'm surprised you listed the Juin Tech F1 calipers as bad. I have mine setup on my road bike and they work just fine. I do nothing but climbing and descending as well and I've been lazy to swap over Ultegra R8020 hydraulic shifters I have. Though I'm using higher tension gold brake cabling and semi-metallic finned pads that were released in the last few months. It's made a huge difference in performance.

Re: Best way to Chinertown road disc groupsets? :) If you're sticking to Shimano, Sensah now offers hydraulic Shimano compatible 11 speed shifters now. Apparently 12 speed shifters will follow soon. Also I go back and forth between my Sensah and Shimano equipped drop bar bikes no problem.  Though I only use Shimano front/rear derailleurs and chains (I don't touch aftermarket chains), but I have no problem using AliEx cranksets which I think are quite mature at this point. I do think Shimano cassettes are still better at shifting though, but I am currently using a lightweight SRoad/Spedao cassette on one of my road bikes. I'm also using Onirii disc rotors on my road bikes and Shimano Ice-Tech rotors on my gravel bike.

There's lots of room for mixing-n-matching, I actually find it more fun having a customized setup. I get bored looking at the same LBS bought bikes with no personality.

What chemical, if any, do you use to clean new chains ?

Not as intensive as PLA, but about two rounds of degreaser in the ultrasonic cleaner, a brush scrub down and dry pat down before dipping the chain into the slow cooker. My wife thinks I'm cooking something outside in the backyard! Lol

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc! Avoid the Rotor knock-off chainrings on AliExpress usually sold as Racework or Zeroing 2x chainrings. I had chain rub issues on the small chainring which required about 2mm of spacers on the drive side. I recently swapped it out for a Senicx 2x chainring. Chain line is perfect with no spacers (on par with a Shimano crankset) and smooth FD shifting. The Sensah store sells them for fairly cheap, especially during the sales. The outer chain drop pin is a bit long for many cranksets, but you can remove them by unscrewing.

Speaking of chainrings, any feedback on Pass Quest? The product pages look good, kinda pricier but quality seems better than average AliEx 'rings. In fact, I am trying to replace FSA rings on my Cannondale and these PQ rings are more expensive than FSA original. They are lighter than Cannondale's 10 arm OPI rings though.

They're definitely worth the price. I'm using a Pass Quest 1x aero chainring on my gravel bike. Today I cleaned up my chainring since I went with an immersive waxed chain and the teeth still look really good with minimal wear. These are one of those items that are worth the slight price increase for a step up in quality and durability.

On a side note the Expedition and Newbike Stores (same vendor) are also one of the better sellers on AliEx. I've ordered multiple items from them and they're quick to ship.

Re: Nich Cycling (Thailand) - Legend4 Frameset - UCI Approved Living in the biggest west coast US city with year round cycling weather, I very rarely (pretty much never), see any Chinese bike frames. I'm always looking! The Freds and Crit bros would rather pay monthly car payments for their $10k plus S-Works bike or their custom titanium frame sprinkled in pixie dust.  I don't think people want to spend several grand just to deal with overseas customer service.

Hey Everyone!

First post but I have glanced on the site for a little while.

To make a long story short - I recently suffered from loosing my bike from my bike rack (gravel bike) and then I also suffered from the shimano recall on multiple bikes.

I am a huge DIY guy and service every aspect of my bikes and I am kind of fed up with main stream stuff.  I want to try and build a chinese bike (gravel) and had some questions about a frame I found on Ali that fits every criteria I want/have.

I don't care that its a "scott" knock off - its the geo and integration that is exactly what I need.  The seller is very old and crazy responsive - is there anything else I should look for/do?

https://www.aliexpress.us/item/3256805813051230.html?pdp_npi=3%40dis%21USD%21US%20%24800.00%21US%20%24632.00%21%21%21%21%21%402101c5c216986738778255663e05d8%2112000035245936578%21im%21%21&gatewayAdapt=glo2usa4itemAdapt

Ask A LOT of questions. Get a spare derailleur hanger if possible, make sure they face the brake mounts properly and double check there are no headset issues. You'll probably run into small issues regardless. Also get one of those internal routing cable kits. Don't over torque the BB especially if you plan on using a threaded PF bottom bracket. Overall though it's extremely satisfying putting together your own bike.

Thank you for your response!

I have a couple questions to your post and appreciate your time.

1.Face the brake mount properly - these are flat mount calipers, are you saying to just add a note to ensure all face mounting is done?  I am sure I can rig something up if not (I have some machining background)

2.When you say "double check there are no headset issues" what do you mean by that? - As in are you saying to ask the seller or when you receive the bike check for bearing fitment? 

I will Endoscope the frame/fork/bars when I get it to see how the layup looks and if there are any crazy wrinkles/bubbles/delamination/resin pooling.  I also plan on using a BBinfinit PF bottom bracket (huge fan of this company), are you saying generally these Ali or Chinese frames are weaker in this area?

I have been asking lots of questions to the seller and they are stellar and quick with responses.

Thank you again for all the help.

These are just general preventative measures to ensure your bike build goes smoothly. If you plan on having the frame painted, sometimes the overspray might cause the caliper alignment issues, though that can happen with mainstream frames as well and this is something I always ask the seller so they can send me photos. There are a few posts on here regarding headset issues with internally routed frames. I would just make sure everything fits properly before going on your first test ride. I don't think the frame will have any BB problems, I have an AliEx BB86 road frame myself that's been rock solid. Lastly make sure you have all the right grease, carbon paste and a preset torque wrench as well.

I'd also ask for pictures prior to shipment just to make sure everything is in proper order.  I've had a pretty smooth track record with AliExpress, though there's always a bit of risk involved especially if you're the small percentage with defective frame issues. So it's best to mitigate any problems beforehand. Best of luck!
