I bought a couple of sets of bars from Aliexpress, one 12 degree and one 25 degree flare. The wide bars were Zniino carbon 25 degree flare and 220g, the bar was too thin for my comfort and I couldn't stop the shifters from slipping down, even with carbon paste. I also got the Uno F12 bars (12 degree) Alloy bars at 290g.... I preferred the Uno but in the end I went ultra wide with some half price Ritchey Beacon bars (alloy but only 270g)... I used this site to look at options, then tried to find the cheapest offer from anywhere including Aliexpress

I also opted for 4.5mm bar tape for extra comfort, no complaints. I prefer the Alloy bar, with thick bar tape.. just more ability to tighten shifters and have confidence in the strength of the bars when rattling over rough terrain at speed.
