The bike is fairly nice, but has some significant issues that potential buyers need to be aware of before parting with $900 of their hard-earned money.I've put 250 miles on this thing so far, with (only) one major incident. The seat post broke off right where it comes out of the frame, which is not the nicest thing in the world. Fortunately, it broke off clean so there weren't any jagged edges to worry about, and the seller sent a replacement promptly.The broken seat post shows some stress marks on the inside, and seems to be quite flimsy. It's an alloy tube with a carbon fiber coating, and both the alloy and the carbon are too thin to rely on. The replacement tube is the same type that comes with the frame so I don't trust it. I've bought an alternate seat tube from Amazon that seems a lot more sturdy.The product description is very misleading and not even consistent with itself. The title "HASA Shimano 105 Carbon Flat Bar Road Bike" makes it sound like the bike has a carbon frame, but it's aluminum, as the small print at the bottom makes clear. The description says it has a "compact 50-34 crankset and corresponding 12-25 cassette" which is also untrue. It has 3 ring crankset and a 11-28 cassette, as the small print also says.The sizing indicated in the chart (one of the pictures) is not accurate. The frame is actually smaller than the chart indicates. Instead of the top tube in the 56 cm bike running 568.2 mm as the chart says (which would be 22.37 inches,) it measures about 21.5". This is one size off and makes a big difference in the fit.The components are good quality, mostly Shimano 105, middle of the road quality level. In the Shimano road bike parts world, the hierarchy from best to worst is: Dura Ace, Ultegra, 105, Tiagra, Sora. The seller claims the bottom bracket is Dura-Ace level, but I can't confirm that from Shimano's web site. It's certainly not an expensive part. There's nothing wrong with it, as far as I can tell, but it shouldn't be the main reason you buy this bike.The hubs are made by a Taiwanese company that's not one of the big names in cycling, but they seem to work well. They're held together by aluminum collars and set screws instead of pairs of nuts, so I expect they'll need more attention than mainstream hubs. The seat post, handlebars, and front fork all also no-name Taiwanese parts, and as mentioned the seat post is garbage. The front fork and handlebars haven't broken yet.The seat and pedals are throw-aways, but that' the norm in road bikes at this price point. I already had my own favorite seat and pedals and there wasn't any issue with swapping them over from my old bike.The bike shifts well, it's quite light, it's a good climber, and it's fast. Aside from the sizing and durability issues, it's not a bad buy.

I've been very happy with this bike. The assembly was not that difficult - took maybe an hour. No adjustment was needed for shifting, and only minor adjustments were needed for the brakes. When I compared the specs listed here on Amazon to what the manufacturer has on their web site, there were some differences. However, the bike I received is exactly what was specified here. I've ridden about 500 miles so far. The only issue I've had was two spokes that broke. I'm not sure why that happened, but it was an easy fix and no problems since then.
