Radon R1 Tiagra

The "R1 Tiagra" model from the Radon brand is a high-quality racing bike that is available for a price of EUR 1299. The frame of the bike is made from the R1 model and contributes significantly to the low total weight of just 9 kg. The brakes are of the Shimano Tiagra BR-R4770 type with a modern flat-mount fixing, which ensures reliable braking performance.

The derailleur is a Shimano Tiagra RD-4700-GS with 10 gears, which, together with the Shimano Tiagra ST-4720 shifters, enables precise and smooth gear changes. The front derailleur is a Shimano 105 FD-R7000, which is mounted clamp-on. The fork of the bike is made entirely of carbon, which also contributes to the low weight and stiffness.

The bottom bracket is a Shimano BB-RS500PB with press-fit technology, and the crankset is a Shimano Tiagra FC-4700 with a gear ratio of 50/34T. The handlebars are a LEVELNINE Wing Race with a diameter of 31.8 mm, while the grips are made of RADON performance tape. The stem is also from LEVELNINE and is labelled Race, also with a diameter of 31.8 mm.

The headset is a VP IS42/IS52, and the rims are Alexrims ATD560, which are robust and lightweight. The tyres are Continental Ultra Sport 3 in size 28" x 28mm and offer a good balance between speed and comfort. The spokes are Pillar CDB1415 ED in black, which gives the wheel an elegant look.

The saddle is a Selle Italia Model X Superflow, which ensures a high level of comfort on long rides. The seat post is a LEVELNINE Race measuring 27.2 x 350 mm. It should be noted that pedals are not included, so the buyer must purchase these separately.

Overall, the Radon R1 Tiagra offers high-quality equipment at a fair price and is ideal for ambitious road cyclists.
