LTWOO R7 2x10s Road Rim Brake Groupset (ST-R5110, previous generation)

The reviewer purchased and tested the LTWOO R7 2x10 speed rim brake mechanical groupset from AliExpress for £62. They installed it on a Cannondale road bike and used it for several months through winter, including commutes and rides in the Peak District. They describe it as a complete groupset including shifters, derailleurs, brakes, cassette, and chain, requiring only a separate crankset. The reviewer is impressed by the extremely low price and functional shifting performance but notes significant drawbacks in weight, chain retention, build quality, and setup difficulty.
