Brake type Hydraulic Disc

Brakes 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.

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.
