We often associated Chinese bike parts for shoddy quality, one day life span and for low end plastic products - horns, lamps, plastic accessories. and others like seat posts, saddles, handlebars.
But it is no longer true today if you follow the e commerce platforms. They are into the mainstream of bike technology and may have overtaken the rest of the world
4 Cogs: Sunrace, Z race Sagmit, Ztto. Even lighter than the original manufacturers You can find much lighter cogs at 300 grams + only but with hefty prices
5 GS - LTWOO, Senshah. Restrospec. LTWOO was established by former head of R & D of SRAM
Even for rear lamps of Rockbros (they are now into Q5) you find advanced features as: stop light, automatic shut off at daytime, on at dusk, etc. I only have the q3
Now is the time to take advantage of low priced products while Chinese producers are trying ot build brands and market share (it means while prices are still low)
We are not pro Chinese. This post is pro savings pro more money in the pocket/bank
