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

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

The reviewer discusses the Magic Shine Alti 400 front light, which they state is the most commonly used front light in their collection. They mention using it for 90% of their rides due to its small size and adequate brightness for their typical riding conditions with street lighting.

"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.
