Road bicycle Schwinn Fastback 1 – 105 FULL groupset – $626 size 54 (seat tube)
https://www.amazon.com/gp/product/B01M4M40K4
The groupset is 105 5800 full – with cranks and brakes – unlike many other bikes that claim they have 105.
Just new 5800 groupset retailed for $400.
Frame is aluminum with carbon/alloy fork (650g – fork)
Wheels are 1800g (I measured). (Without tires, tubes, skewers, cassette, but with rim tape.) 14C.
Bike weights 9.4kg size M, without pedals.
Seller is Amazon itself. Price is very dynamic. I think it’ll go away when the first bike will be purchased at this price. (This happened to my purchase, it went to $880 for 51 frame.)
Sizes: notice that sizes are for SEAT tube, not top tube as for other bikes. Here is link to Geometry chart:
