I m interested in buying a mtb and have recently visited decathlon to get a view of btwin bikes. Btwin 520 is the bike for which i m looking upto. But i dont want a dual Hydraulic brakes as they require lot of maintenance and i dont want to visit thier service center again and again. i will prefer a v-brake bike and my budget in 25000 t0 30000. Please suggest me a good bike in that range . Thank you!!
