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.

AI Summary

Pros

Extremely low price (approx. £62-£73)
Complete groupset includes shifters, mechs, brakes, cassette, and chain
Shift quality is spot on and reliable once dialed in
No missed shifts during testing
Campagnolo-inspired ergonomics with a long thumb lever are comfortable and accessible
Hood profiling is comfortable and provides a positive grip
Compatible with a separate gravel rear derailleur (GR7) for added versatility
Heavy-duty steel cassette is durable and unlikely to wear out quickly
All components held up well over approximately 500km of use
Good value for a winter, training, or commuter bike where weight and premium feel are not priorities

Cons

Weak rear derailleur spring leading to poor chain retention and chain slap
Not suitable for off-road use due to chain retention issues
Very heavy overall
Overall fit and finish is not premium, with rough edges and cheap-feeling materials
Shifters and mechs have a rough finish compared to premium groupsets
Does not include a crankset
More difficult to index and dial in than Shimano 105 or Di2
Shifting has a positive 'clunk' rather than a smooth, gliding feel
Brake calipers are very basic (Z race BR001)
Cassette is a heavy solid block of steel
