Where it stands
Priced close to what German shops charge for this level of equipment, so it does not clear the margin we require before naming a pick.

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.
- 15.8 kg, on the heavy side for a mountain bike; the ranking's reference weight is 14.7 kg.

What bikes.de lists, and what it has today
Centimetre equivalents are the ones the shop prints beside each letter size. This brand publishes no centimetre equivalence we can verify, so the bike appears only when you pick a letter size.
