The 2021 "Vapor 1*11 Python" model from Stevens is a high-quality bicycle that stands out for its well-thought-out specifications and light weight. It is available at a price of €2,099 and offers a wide range of technical features that make it an excellent choice for discerning cyclists.
The bike’s frame is made from SL 7005 TB aluminium, ensuring a robust yet lightweight construction. The maximum load capacity is 115 kg, whilst the bike itself weighs just 8 kg, contributing to its excellent handling and lightness.
For the brakes, Stevens has opted for the Shimano GRX 810 BR-RX810 model, which is renowned for its reliability and powerful braking performance. The derailleur is also from Shimano – specifically the GRX 810 RD-RX810-D model – and offers 11 speeds, enabling precise and smooth gear changes. The crankset is the Shimano GRX 810 FC-RX810-1 with 40 teeth, whilst the cassette is a Shimano CS-HG700, also with 11-speed gearing.
The fork on the Vapor 1*11 Python is made from STEVENS Full Carbon SL HMF, which contributes to further weight reduction and improved damping. The bottom bracket is a Pressfit BB86, which is valued for its stiffness and durability.
The handlebars and stem are both models from the Oxygen Scorpo series, with the handlebars being the aero version to minimise drag. The headset is a STEVENS Race Taper with dimensions of 1 1/8"–1 1/2", ensuring precise steering.
Contact with the road is provided by Schwalbe X-One Allround Performance tyres in size 33-622, fitted to a Fulcrum Racing 600 DB DRP wheelset. This combination offers an excellent balance between grip and speed. The saddle is an Oxygen Triton, which, together with the Scorpo Road seatpost, ensures comfort even on long rides.
Overall, the 2021 Stevens Vapor 1*11 Python is a well-designed and high-performance bike that is suitable for both ambitious amateur cyclists and professionals.
