The "GRV 8.0 Diamant" model from Conway from 2024 presents itself as a versatile and powerful gravel bike that, with a price of EUR 1899, is an attractive offer for cyclists who want to be on the road as well as off-road. The frame of the bike is made of lightweight aluminium and has a diamond shape with a frame size of 53 cm. The permissible total weight is 130 kg, while the bike itself has a weight of 10 kg, which contributes to its agility and manageability.

The braking system of the GRV 8.0 Diamant is equipped with SHIMANO "GRX BR-RX400" disc brakes, which work with 160 mm diameter SHIMANO "SM-RT54" brake discs at both the front and rear. The brake levers are also from SHIMANO and belong to the "GRX ST-RX600" series, which guarantees reliable braking performance. The shifting system comprises a 22-speed SHIMANO "RX810" mix, which is operated with the "GRX ST-RX600" model shift levers. The front derailleur is the SHIMANO "GRX FD-RX810", while the crankset is specified as the SHIMANO "GRX FC-RX600 11" with 30/46 teeth and a length of 172.5 mm. The sprocket consists of the SHIMANO "HG700" with a gradation of 11-34 teeth, and the drive is provided by the SHIMANO "HG601".

The fork of the bike is made of carbon and designed for disc brakes, which helps to reduce the overall weight and improves the riding dynamics. The handlebar is a CONWAY "GRV Bar 440", complemented by FIZIK "Bar Tape" grips for additional comfort. The stem is the CONWAY "GRV A-Head 90" with a diameter of 31.8 mm. The headset is configured in the sizes IS42 / IS52.

The wheels are equipped with MACH1 "Gravel 19" rims, fitted with CONTINENTAL "Terra Trail" tyres in size 40-622. The hubs are from SHIMANO, with the front hub as "HB-RS470" and the rear hub as "FH-RS470", both with thru axles (12 x 100 mm front and 12 x 142 mm rear). The spokes are made of stainless steel, which provides additional stability.

The saddle is a SELLE ROYAL "1220", mounted on a CONWAY Patent seat post with a diameter of 27.2 mm and a length of 350 mm. The geometry of the bike is characterised by a stack height of 588 mm, a seat tube length of 530 mm and a top tube length of 575 mm. The seat tube angle is 74 degrees, while the head tube length is 170 mm. The chainstay length is 435 mm and the wheelbase measures a total of 1073 mm, which contributes to a balanced and stable riding style.
