This Ryet RS OSPW is actually really good because it has properly sealed bearings. I've done about 1000km often on wet and dirty roads with it now and it spins like new without any need for oiling and stuff. I didn't open or measure the bearings but they looked like some standard sealed bearings from the outside.

I've had this on my gravel bike for 2 years. No electrical tape, no additional loctite (there might've been some from the factory) and it holds perfectly. It looks clean and I can put the bike in the workstand without the radar being in the way. One of my favourite little bike accessories.

I got this jersey here. With a undershirt and a gilet been good for about -5C It’s got long arms and tight hems. Long enough for me and quite snug which I like. The color is a bit muted. I’m 193cm and 78kg with a 102 cm chest. Went with a European L as per size chart. Could’ve been an XL for looser fit.

Just to give you some peace of mind regarding the build quality: I honestly didn't run into any of those brake issues you mentioned. I consider myself a bit of a mechanical 'noob,' yet I managed to align the calipers perfectly on the first try without needing to face the mounts or use special tools. It was good to go out of the box. As for reliability, I've logged nearly 5,000km on this frame so far and taken it absolutely everywhere. It has survived various Gran Fondos and I even took it up the Colle delle Finestre—if you look up that route, you'll see it's a brutal climb with heavy unpaved/gravel sections at the top. The frame handled it without a problem. I wouldn't hesitate to buy it again. The only slight pity is the total absence of logos/branding, but performance-wise, it's been solid.

The reviewer discusses the LTWOO (referred to as 'L2' or 'L2 group set') R9 disc groupset, which they state costs 108 quid on AliExpress. They explain that while cheaper groupsets like this are rarely as good as Shimano equivalents out of the box, with specific tweaks they can come incredibly close to Shimano levels of performance. The video is dedicated to sharing tips for improving the performance of this and similar budget groupsets. The tips cover mechanical shifting, cable routing, component wear, shifter rattle, and the specific process for bleeding the hydraulic brakes, including unique features like a grub screw on the brake lever. The reviewer also mentions that newer LTWOO groupsets have a tension adjustment screw on the front derailleur.

Pros

  • Can come incredibly close to Shimano levels of performance with a few tweaks.
  • Very low cost (108 quid on AliExpress).
  • Uses mineral oil for brakes (not DOT fluid).
  • ...and 2 more

Cons

  • Out of the box, it is rarely as good as Shimano equivalents.
  • Shifting can feel vague or mushy compared to Shimano due to tolerances and return springs.
  • The rear derailleurs use a slightly older, more dated design with a standard hanger bolt (not a B-link).
  • ...and 4 more

Key Points

  • Cost: 108 quid on AliExpress.
  • Type: Mechanical shifting, hydraulic disc brake groupset.
  • Brake Fluid: Uses mineral oil.

The reviewer mentions the Sensah brand several times throughout the video, but does not specifically discuss the 'SENSAH EMPIRE HRD 2x11s Road Bike Hydraulic Disc Brake Front Derailleur Rear Derailleur Carbon Shifter Bike Parts' as a complete, named group set. They refer to Sensah group sets in general, sharing tips applicable to them and other cheaper groupsets from brands like LTwoo. Specific mentions include that Sensah shifters can rattle, that Sensah hydraulic groupsets use mineral oil, that the bleed port on Sensah shifters is recessed and at a funny angle, and that Sensah front derailleurs lack a built-in tension adjustment screw.

Cons

  • The reviewer states that Sensah shifters can rattle, a common issue with cheaper shifters.
  • They mention that the bleed port on the Sensah shifter is recessed quite far and at a funny angle, making bleeding trickier.
  • They note that Sensah front derailleurs do not have a built-in tension adjustment screw, requiring an inline barrel adjuster on the cable run.

Key Points

  • Sensah groupsets use mineral oil for hydraulic brakes, not DOT fluid.
  • The bleeding process for Sensah hydraulic groupsets is broadly the same as Shimano but may require different adapters due to thread sizing and port location.
  • Sensah rear derailleurs tend to use a slightly older design with a standard hanger bolt, requiring a larger cable loop for optimal shifting.

I've been using the Rockbros socks for about a years now. I have a pair in each colour offered. I find them very durable. I use them for running too. My first pair, in black, has probably been through the wash 20 times and is still in good shape! I had very little faith in them when I first ordered, and thought what can I lose for £2ish. I just thought they were too cheap to be any good, but I've been very pleasantly surprised.

Hi I have two in use a 27.2 and 31.6 mm several thousand miles on each , rain and rough roads. So far so good only suggestion would be at the clamping area use Teflon paste or a good grease on the carbon to carbon interface. I had a little creaking on the 27.2 the Teflon paste worked well never touched it again.

I took my R088 on our local Hollywood Sign climb route. It climbed and descended like a champ. Also the 0° setback seat post has made this bike even better with perfect saddle positioning. Seriously, I have zero complaints with this frame. For the price and configuration flexibility is there a better bang-for-buck carbon frameset? You can run electronic or mechanical, setback or no-setback seat post and integrated or non-integrated bars. Plus there's UDH, threaded BSA and standardized 52mm headset bearings.

I had huge fun replacing almost all the nuts & bolts on my bike(s) with titanium ones. I mostly stuck to the brands Taimeili, Wanyifa and XMSJ Titanium Accessories. Through spark testing I can confirm it's at least *a* type of titanium alloy (bright white sparks), and nothing failed until now, so maybe it's actually grade 5 Some of the bolts used: Limit screws (RD, B-Tension and FD support), RD pivott bolt (R8100), various Brake caliper bolts (BR-R8170), Caliper fixing screws (rear), Bleed port & flange nut (ST-R8170), Flange nut (ST-R8170, also works), FD mount, Stem bolts, Saddle Clamp (marketed as "SL7", also works with my Factor Ostro - literally identical dimensions), Chainring bolts (the 10,5mm long version works with R8100 chainrings), M6 Nuts for single pivot rim brakes (13mm long version works great for the STI clamp), Brake pad axle. These are the most 'bike specific' ones, other than that, I've ordered some regular nuts & bolts (e.g. countersunk screws, regular nuts or panhead screws) for various things like computer mounts, ahead caps and so on... Adding everything up, I was able to save around 58g on one bike through titanium bolts for ~115€ (using coins and Choice Day-/Singles Day-/Black Friday-coupons)

The reviewer has used the Winspace T1600 as his primary race and training bike for approximately seven months, covering around 6,000 kilometers. He states the bike has been completely faultless, raced in Germany, the Netherlands, and the UK, and tested in a wind tunnel. The frame is described as extremely sensitive to wheel choice, and the integrated handlebars are highlighted as a significant source of aerodynamic gains. The build quality is praised as flawless, and the bike is noted for being extremely stiff. The reviewer mentions the bike comes as a frameset including the fork, handlebars, stem, and seat post, with the rest being bolt-ons. He also discusses the bike's geometry, noting the XL size has a longer top tube than expected.

Pros

  • Completely faultless over 6,000 km of use
  • Extremely stiff frame
  • Flawless build quality
  • ...and 5 more

Cons

  • Frame geometry can be tricky, with the XL size having a longer top tube than the labeled 540 size suggests
  • The frame is extremely sensitive to wheel choice; a wide tire and wheel combination can increase drag more than the rolling resistance benefit
  • The reviewer is not totally convinced the winglets provide a significant aerodynamic benefit

Key Points

  • Used as a race and training bike for ~7 months and ~6,000 km
  • Frameset includes fork, handlebars, stem, and seat post
  • Bottom bracket is BB T47 / T47 with an 86.5mm shell

The reviewer purchased the Magene PES P515 power meter crankset from AliExpress for £225 to improve their winter training. They were greatly impressed with the results and found no downsides. The reviewer found installation straightforward as a direct replacement for their Shimano Ultegra crankset. They tested the power meter's performance against Wahoo Powrlink dual-sided pedals and found the data to be accurate, consistent, and reliable, though it read slightly higher. The crank stiffness was comparable to Ultegra, and the shifting performance of the chainrings was very good, nearly matching Shimano's gold standard. The reviewer concludes it scores really well, especially considering its significantly lower price compared to competitors.

Pros

  • Cost just £225 (significantly cheaper than competitors)
  • Greatly impressed with the results
  • Found no downsides
  • ...and 10 more

Cons

  • PES branding is quite bold and could be an issue for some people
  • Not the best branding
  • Initial concerns about the non-drive side crank arm having only one pinch bolt (vs. Shimano's two)
  • ...and 2 more

Key Points

  • Model: Magene PES P515 Power Meter
  • Spider-based power meter
  • Charge port
  • ...and 9 more

"Why risk buying cheap stuff from abroad?"

We love new bike tech and follow bike brands extensively. Riding bike can be a very price intensive thing, but it can be made more accessible by saving some money, and spend it on the parts that matter mostly for you. After a couple of thousand kilometers, most buyer can determine the quality themself. Some YouTubers already have a successful history with using cheaper parts from Aliexpress or eBay. To crowdsource those experiences, we've made this site, to seperate the wheat from the chaff. To be honest, there is also a lot of crap or mediocre stuff out there, but at the same time you can find reliable and quality stuff.
