Diamant Topas Grande Finale (Einstieg: tief)

The “Topas Grande Finale (low step-through)” model from Diamant, released in 2022, is a bicycle that impresses in terms of both design and functionality. The price of 969 EUR reflects the high-quality components and well-thought-out features. The bike’s frame is the Diamant Topas-Swan Frame with a frame size of 53 cm, ensuring a comfortable and stable ride. The maximum load capacity is 136 kg, guaranteeing a robust construction and high load-bearing capacity.

Safety and control are ensured by the Shimano T4000 V-brakes on the front and rear wheels, combined with aluminium Tektro brake levers that offer an adjustable grip width. Gear shifting is handled by the ASLC60008DXS210LA gear lever, which, in conjunction with the Shimano Nexus 8-speed hub gear system, enables precise and reliable gear selection. The rigid steel fork contributes to the bike’s stability.

To ensure good visibility on the road, the bike is fitted with a Diamant Retro LED front light and an AXA Ray Steady LED rear light with a parking light. The retro steel pedals with rubber pads provide good grip whilst riding. Power is transmitted via a KMC S1 chain drive, whilst the crankset consists of forged aluminium with 38 teeth and a Shimano 19-tooth sprocket.

The Humpert Courier handlebars, with a diameter of 25.4 mm, and the stitched Diamant Retro grips offer comfort and control. The cold-forged aluminium stem, fitted with stainless steel bolts and an 80 mm extension, ensures stable steering. The Schwalbe Fat Frank tyres, featuring KevlarGuard puncture protection and reflective strips, offer excellent traction and safety.

The wheelset comprises BONTRAGER rims, renowned for their stability and durability, supported by a Shimano C3000 hub dynamo. The Diamant Retro saddle and the Bontrager aluminium seatpost provide additional comfort whilst riding. Mudguards made from Büchel Metall Nirosta protect against dirt and water, whilst the Atran Moove kickstand ensures the bike stands securely.

The specification is rounded off by the Diamant Retro steel luggage rack, which is InterChange-compatible, offering flexibility when transporting luggage. The bike’s geometry is well thought out, with a head tube angle and seat tube angle of 70 degrees each, a seat tube length of 53 mm, a top tube length of 60 mm and a wheelbase of 114 mm, ensuring balanced riding dynamics. The packaging measures 23 mm in width, 119 mm in height and 190 mm in length. The Topas Grande Finale is therefore a successful combination of classic design and modern technology, ideal for the urban cyclist.
