Stevens Tonga

The "Tonga" model from Stevens, released in 2023, is a versatile mountain bike that stands out for its solid spec and excellent value for money. Priced at 749 EUR, the Tonga offers a reliable and robust platform for a variety of rides and terrain types.

The bike’s frame is made from 6061 aluminium, which ensures a good balance between stability and weight. The maximum load capacity is 115 kg, whilst the bike itself weighs 14 kg, making it a relatively lightweight mountain bike in its price range.

The Tonga’s braking system is fully equipped with Tektro HD-T275 components, both front and rear. The brake discs are from Shimano, measuring 180 mm at the front and 160 mm at the rear, ensuring reliable braking performance. The gear system consists of an 18-speed Sunrace RDM91, operated via Shimano Acera shifters (SL-M3010 and SL-M3000). The front derailleur is a Shimano Altus FD-M2020-TS, which ensures precise gear changes.

The Tonga’s fork is an SR Suntour XCM DS with 100 mm of travel, which provides good suspension on uneven terrain. The bottom bracket is a 73 mm BSA, whilst the crankset varies depending on the wheel size: The 27.5" version features a Shimano FC-MT210-2, whilst the 29" version features an Oxygen Scorpo with 36-22 teeth. The cassette is a SunRace CSM98 with 9-speed gearing.

Comfort and control are ensured by the Oxygen Driver handlebars, which are 740 mm wide, and the matching stem. The headset is a STEVENS MTB 1 1/8". The rims are Oxygen RM-M19, both front and rear in size 19 x 584. The tyres are Schwalbe Smart Sam Active-Line, also available in sizes 27.5" (57-584) or 29" (57-622), depending on the model variant.

The hubs are a Shimano HB-TX505 at the front and a Shimano FH-TX505-8 at the rear, ensuring reliable and long-lasting performance. The saddle is an Oxygen Raceline, mounted on an Oxygen Driver seatpost, which offers additional comfort. The pedals are ATB Pro Reflex, which ensure a secure grip and safety.

In summary, the 2023 Stevens Tonga offers well-thought-out, high-quality components at a fair price and is ideal for both beginners and advanced mountain bikers alike.
