The compromises
- Mixed groupset: not every component is Shimano XT.
- Mechanical shifting, at a price where electronic groupsets are common.
- Wheels not identified from the listing, so we scored them level with basic aluminium rather than guess.
- No power meter, which many bikes at this price include.
