The Alvar 2 Diamant model from KAYZA, released in 2023, is a versatile and well-equipped bicycle priced at 849 EUR. With a maximum load capacity of 130 kg, it features a robust design suitable for a variety of uses. The braking system consists of black PROMAX “TX123” V-brakes, fitted with 160 mm brake discs at both the front and rear, ensuring reliable braking performance. The 21-speed SHIMANO derailleur – specifically the “TX800” model – is complemented by SHIMANO “ST-EF41” shift levers and offers a wide range of gears for different terrain conditions.
The SUNTOUR “SF16-NEX-P-700C” fork, with 63 mm of travel, helps absorb shocks on uneven terrain and improves riding comfort. The VP “BC73 C” bottom bracket, with a length of 122.5 mm, and the SHIMANO crankset "FC-TY301" with 24/34/42-tooth chainrings and a length of 170 mm ensure efficient power transfer, supported by the KMC "Z7" chain. The CONTEC “Mito60” handlebars have a diameter of 31.8 mm and a width of 660 mm, enabling comfortable and stable steering. The CONTEC “MTB Straight long” grips offer additional comfort on longer rides.
The bike is fitted with KAYZA “X-ALT X2” hollow-section rims, combined with SCHWALBE “G-ONE Bite” performance tyres in size 45-622 with bronze-coloured sidewalls. These tyres offer good grip and stability on a variety of surfaces. The SHIMANO hubs – the “HB-TX500” at the front and the “FH-TY500” at the rear, both with 32 holes and finished in black – contribute to the bike’s durability.
The black CROSS “Corex” saddle and the CONTEC “Pillar” seatpost, with a diameter of 27.2 mm and a length of 400 mm, round off the comfortable specification. Overall, the Alvar 2 Diamant offers a balanced combination of comfort, functionality and style, ideal for everyday commuting as well as sporty rides.
