Pneumatici
So you feel safe on any terrain, and to provide traction suited to your motor, the E-ST900 mountain bike is equipped with Hutchinson Taipan Koloss 27.5+ tyres with a 2.8" cross-section. Our test riders particularly liked these tyres for their grip on the ground. Mounted on wide rims, these tyres ensure grip, traction, and comfort on any terrain.
Freni
Tipo di freno
Hydraulic Disc
Descrizione del freno
No matter the conditions you ride in (dry, muddy, wet), the Tektro TKD32 hydraulic disc brakes on the front and rear provide powerful, progressive braking. Oversized 180mm diameter discs provide even more power.
Seduta
Sella
Since your mountain bike rides will get longer and longer, it is important to sit comfortably. So our teams designed the exclusive ROCKRIDER Ergofit Pro saddle. It fits all hip sizes and has a curved shape that is particularly good for sport trail rides. The 31.6 mm aluminium seat post ensures compatibility with most adjustable and suspended seat posts on the market.
Componenti Elettrici
Motore
The BROSE T Aluminium central motor is specially designed for high altitude mountain biking: - 70 Nm torque to handle large obstacles and steep gradients - metal housing for maximum durability - belt for an ultra-quiet motor - and sealed bearings to withstand the sometimes adverse weather conditions of mountain biking
Batteria
Our Rockrider mountain bike team has designed a battery that locks in place with a simple lever. Child's play! This locking system prevents the battery vibrating when riding on rough terrain. A key lock is also installed if you want to protect your battery from theft. For example, if you park your bike in the street.
