What a small facelift can do: Technically, the Spire frame is unchanged for the current model year, but thanks to the new graphics, the bike looks much more attractive and independent. The sporty impression it conveys thanks to the short head tube and sloping top tube is confirmed in practice. Here, the Spire turns out to be a thoroughbred racing machine: very stable with precise steering and unagitated steering geometry. The frame also offers noticeable suspension comfort thanks to the HiFlex seatpost from Syntace. A Radon wouldn't be a Radon if it wasn't opulently equipped. The high-profile wheels from Mavic are a highlight, offering clear aerodynamic advantages over wheels with flat rims and are also very suitable for everyday use. Only the saddle looks a little cheap, but is not uncomfortable.
