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.

- Aluminium frame, at a price where carbon is common.
- No power meter, which many bikes at this price include.
Your size
What BikeExchange lists, and what it has today
This brand publishes no centimetre equivalence we can verify, so the bike appears only when you pick a letter size.
Where to buy
Other shops list what looks like this bike, but we cannot confirm it is the same build, because the model year or drivetrain is not settled, so we do not compare their prices.
Price so far
€3,900 at every one of our 4 checks since 16 Sept.
- BikeExchange states an RRP of €4,799 (19% off). That is the shop's claim; we rank on today's price, never on the discount.
